Industrial electronic repair services offer repair for a variety of components, drives, welding controls, robotics, etc. from multiple manufacturers. When trying to find a repair service, you might come across the phrase “electronic repairs to OEM specifications.” The term OEM means “original equipment manufacturer” and is used to refer to the company that originally made the product. The product is then retailed under the purchasing company’s brand name.

With repairs, OEM specifications are often used to repair products and/or build new parts. So although the product is not being repaired by the actual OEM, the repair service does use OEM specs to match the manufacturer’s quality and materials. One example of this type of service Carotron, Inc., a company that now offers electronic repair service for a variety of brands such as Yaskawa, Siemens, Vacon, Danfoss, Baldor, Ambitech, Reliance, and even Carotron’s own products. The products that can be repaired include printed circuit boards, ac/dc motors and drives, programmable logic controls, robotics, power supplies, temperature controllers, terminals/displays and others. When ordering electronic repair service, be sure to ask about OEM specifications as well as warranties and a free cost evaluation. Doing so will ensure you’re getting the most reliable repair service available.

Human Machine Interface (HMI) is utilized a great deal in manufacturing, including the process control system. HMI devices are graphics-based products that provide a means of visible monitoring by machine operators, floor managers and workers, and others. The devices are usually installed in an office-based Windows computer. This computer communicates with a special computer in the plant. Feedback is given to the operator or floor manager so the operator can make the appropriate operating decisions.

Any Human Machine Interface should be designed to produce a system that makes it easy, safe and enjoyable to operate machinery. HMI also helps to ensure improved productivity for the work place. Companies such as Red Lion continue to produce reliable HMI products for industrial needs. In fact, Red Lion’s popular G3 Series provides complete HMI functionality for motor drives, PLCs, and other communications devices.

If you need to set up a Human Machine Interface for your work place, contact a distributor to discuss your needs. Carotron, for example, sells Red Lion HMI products along with its own brand of motor controls and system interface cards. It’s easy to see how the right HMI setup can help your operation run more smoothly, thus saving time and money for your company.

Advanced frequency inverter AC drives such as the SMVector NEMA 1 AC drive by Lenze-ACTech can provide a number of benefits in the ceramics industry. These drives are utilized in applications which feature AC motors to operate heavy duty machinery and other equipment. In the ceramics industry and other similar industries, possible uses (whether directly or indirectly) for a frequency inverter AC drive include water supply system, fans for cement and/or air cooling, speed regulation for air conditioning, sewage handling, steel and metallurgy, petrol supply, metal packaging and hydraulic machinery.

Frequency inverter AC drives provide several advantages, including automatic regulation of voltage, tracing and restarting the rotational speed (smoother starts for the motor), non-stop operation during a momentary power outage, and easy operation with digital control panels. Also, frequency inverter AC drives are compact so they don’t take up much space in your facility.

Companies such as Carotron, Inc. provide an extensive line of AC drives to meet your needs. Carotron offers drives from Lenze-ACTech, KB Electronics, Yaskawa, Teco Westinghouse and others. So call to speak with a qualified technician about your AC drive needs so your ceramics facility or plant can start realizing the tremendous savings!

DC injection brakes can be used to slow an AC motor in many different industrial applications. Why is this type of AC motor braking needful? AC motors feature a rotor that spins freely until it is eventually stopped by friction. With larger AC motors that are often used for very large loads, the rotor may spin for quite a while when relying solely on friction to slow it down. This can cause a significant amount of downtime in production operations, when employees must wait on the motor to stop completely before continuing with the next process or step. Also, DC injection brakes provide a way to stop and/or slow the AC motor in case of an emergency.

How does it work? DC voltage is injected into the AC motor’s winding after the motor’s Ac voltage has been disconnected. Doing so provides braking action to the rotor. DC injection brakes can not only help reduce production downtime and address safety issues by providing emergency braking capabilities, but these are also less costly to use. Since they do not have moving components, little or no maintenance is required. Unlike friction brakes that wear out quickly, the Dc injection brakes can be installed easily and left alone to do their job without regular maintenance. This saves money in the long run too. If you’re looking for a reliable AC motor braking solution, consider products such as SAF OP-STOP DC injection brakes. These are designed specifically for industrial uses and can be found through SAF distributors like Carotron, Inc.

If you’re in the market for an AC Tech VFD (variable frequency drive) in the AC Tech MC Series, then first take note that there are four NEMA enclosure offerings with this particular motor control series. There are also two models, MC1000 and MC3000.

The four NEMA enclosures are as follows:

1. NEMA 1: This AC Tech MC Series enclosure is the most common and may be used for general purposes. It should be installed where the environment remains fairly clean throughout the work process. NEMA 1 enclosure helps prevent overheating by allowing for free air exchange.

2. NEMA 12: The NEMA 12 enclosure for MC Series drives is gasketed for protection of the drive hardware/electronics. It may be installed for use in environments where there might be airborne contaminants such as dust or oil. If you need a smaller power size for this same duty, consider the NEMA 4 (described below).

3. NEMA 4: Designed for washdown duty, the NEMA 4 enclosure can protect the electronics from water, keeps the equipment clean and without the need for cooling fans.

4. NEMA 4X: This enclosure is also watertight (like the NEMA 4) but can also protect the electronics from caustic agents. It is made with anodized heat sinks and stainless steel to provide long-lasting use.

Variable frequency drives (VFD) in the AC Tech MC Series provide a number of features to fit a wide variety of applications. Companies that sell AC drives (such as Carotron, Inc.) can provide you with assistance to find the drive that best fits with your operation.

A web guiding system is used to properly guide a web of material through the manufacturing process. Webs may be made of various materials such as thick metal strips, wide or narrow webs, or even thin plastic material. Edge guiding is needed because the web material must remain perfectly aligned to avoid loss of material. If the web gets out of alignment, it may become torn or distorted. This produces unnecessary waste as well as time and money loss for the company.

Three products are used in a web guiding system – linear actuator, sensor and controller. These work in harmony to detect and send signals, which control the web’s movement and alignment. If you’re not sure what type of web guiding system to implement for your operation, then speak with a sales engineer to discuss possible solutions and edge guiding products. For the long term your facility can enjoy faster production and maximized profits with the right type of web guiding system in place.

The vector drive is a type of AC variable frequency drive used as a reliable frequency inverter for a number of tough applications. These offer the best of both DC and AC drives in a single drive. And the good news is these drives are not as complex in design as they once were, which helps reduce the cost as well as complexity of operation. Modern vector drives are now often used in applications where brushless or Dc drives were previously required.

Why are they called vector drives? The term “vector” is used to describe these due to the sophisticated electronic regulator, which controls the direction and magnitude of the AC motor’s magnetic flux through the use of independent control loops. In layman’s terms, this controls the speed and strength of the motor.

Several manufacturers are promoting vector drives today, such as the SMVector NEMA 1 and NEMA 4X drives by Lenze-ACTech. Check the specifications, instructions, features to compare or speak directly with a helpful engineer to find out if this type of drive will work for your application. These frequency inverters can be advantageous and cost-efficient in a number of applications.

Regenerative energy occurs when a heavy-duty motor turns faster than the determined speed of its AC drive. With regenerative energy being used, the motor begins to act as a generator, thus saving energy and helping it operate more efficiently. The energy that’s produced is sent back to the DC bus (where DC power is kept for use by the inverter area). Regenerative AC drives can be used in a variety of applications. Just a few include ramped stopping or slowing of a fast moving load (i.e. mechanical arm or flywheel), industrial saws, drilling operations, packaging and material handling lines, unwinding operation processes in which the drive is used to hold tension against a downstream operation, and many others.

Basically, these types of AC drives can work in most applications that require the driven load to move slower than the load. If your facility or plant needs to replace an AC drive or install a new AC motor, drive and inverter, check around and compare the various drives that are available. Ask to speak with an engineer if you need help with installation or troubleshooting for your older AC motor and drive. AC drives provide a great solution for many types of operations!

In plants and other facilities that operate using heavy duty DC motors, DC drives help the motor to work smoothly at various speeds to reduce energy as well as unnecessary loss of material. The motor drive converts incoming AC volts (single or three phase) to DC voltage. This conversion process enables the safe regulation of torque, speed, voltage and current for the motor. DC drives and motors are used in a variety of industrial processes, including but not limited to paper machines, tube mills, mixers, and many others.

Whether you manage a facility that uses DC drives and motors or are a distributor for industrial controls, find a manufacturer that offers reliable service and quality drives. Also, keep in mind that it’s not always the best choice to replace a DC motor with an AC motor; sometimes replacing the drive is the more affordable option. Some manufacturers offer DC drive retrofit solutions if you or your customer need to replace an obsolete drive.

Buying DC drives is now easier than ever with so many manufacturers offering their services online. You can easily pull up a website and view brochures, instruction manuals, features, etc. without having to request this information by mail. Carotron, Inc., for example, provides .pdf versions of brochures and manuals that can be printed directly from their website. The company does this for all its DC drives including the Elite Pro Series as well as other controllers and accessories.

Having a high quality DC drive with a reliable motor can drastically improve operations at your facility and help reduce production costs!

Proximity sensors can be used in a wide array of industrial applications to detect the presence of items without using any physical contact. These are often referred to as non-contact sensors or dancers. A great example is the Non-Contact Dancer by Carotron that features two models, NCD01-000 without limit switches and NCD02-000 with limit switches. These particular analog proximity sensors can sense cam position giving a 1 to 9VDC output that’s proportional to the angular position of the shaft. They feature a stainless steel, faced shaft for durability and easier installation. If your application uses machinery for which long equipment life is crucial to your operation, then non-contact proximity sensors are recommended.

Non-contact sensor benefits include (but are not limited to) reduced wear and tear, no moving parts or mechanical contact parts, reduced risk of contamination, lightweight, easy to use and embed for moving parts, and many more. As a plant manager or facility owner, your focus is likely to keep a cost effective operation while producing high quality products. Keeping your equipment in top working condition can help you reach these goals! When shopping for proximity sensors, look for non-contact products of high quality and with the features you need. Browse the manufacturer’s website to view brochures, photos, etc. and to save time and money.

Operating a cotton gin at your mill or facility? The ginning process requires preciseness during the short period of time its used each year. Those few months are critical to maximize profits. Unfortunately, ginning machines can wear down in a hurry due to harsh, high-voltage startups. An SAF Solid State Starter (or soft starter) can eliminate or at least minimize this problem. With a soft starter, the cotton gin is started with reduced voltage that is gradually increased. This reduces across-the-line impact loading on drive components, including belts. It lowers demand loading and the cost-per-KWH each month due to the minimization of the AC line inrush current. There are a number of other benefits as well. Loss of production in cotton gin operations always means a loss of profits! Replacement Solid State Starters are available for various designs, including vintage solid state, autotransformer and wye-delta. Ginning machinery can operate more smoothly and efficiently by simply installing a soft starter. So don’t underestimate its amazing potential for your cotton gin operation! If you’re a distributor, be sure to emphasize the many benefits of a soft starter to your cotton gin mill customers.

What are the basic functions and benefits of DC drives? For almost a century now, DC motors have been the “tried and true” motors used in heavy duty industrial applications. These are used to power large machinery such as extruders, web handling machines and many others. And while AC motors have become quite popular in use for fixed speed requirements, DC motors and their accompanying dc drives are often used for more complex needs, such as applications that require wide speed range, ease of control, lightweight and compact motor size, reliable speed regulation, straightforward design and installation, and of course, low cost.

How is control achieved? The speed of a DC motor is controlled by the applied armature voltage. The torque, however, is controlled by armature current. Where does the DC drive fit in the operation? It controls/regulates the conversion of AC power to DC power and controls the DC output voltage and amperage based on feedback signals.

If you’re a distributor offering AC drives, it can be beneficial for your business to also sell DC drives. Some manufacturers (such as Carotron) are still making new innovative DC drives that have advanced, modern features, but also have the same simplistic, rugged design that industrial facilities have grown to know and appreciate. Even if you own or manage a plant or similar facility, determine if you would benefit from replacing just the DC drive instead of the entire DC motor with an AC motor. Doing so might be more cost effective in the long run. DC drives still play an important role in industrial settings when used appropriately in those tough or heavy-duty applications.

Are you in need of an industrial voltage multiplier for your plant or facility? A DC voltage multiplier can be used in applications that require the multiplication of DC signals. For example, Carotron now manufactures a din-rail mountable module that features two inputs, called X and Y. Each of these inputs can be calibrated for the minimum/maximum input levels using the “Teach” terminal. The basic function of this DC voltage multiplier is to multiple Input X by Input Y to find the “output.” There are also special features for dancer trim as well as applications for torque takeup and letoff. Voltage multipliers are typically used to convert electrical power (AC voltage) from a low voltage to higher voltage (DC power). The model MUL270-000 (Carotron’s mentioned above) can work in applications for Generic Trim Potentiometer, Dancer Trim and Torque Takeup/Letoff. Diagrams and drawings, descriptions, connections, dimensions, specs, ect. are available at the manufacturers website for more details.

In industrial edge guiding, it’s important to implement web guiding systems that work smoothly and cost effectively. Web guiding controllers are used to achieve accurate alignment of an edge of film by controlling the position of the web. By implementing a reliable web guiding system, your facility can save money and increase production time. Loss of material is reduced, thus reducing the overall costs of operation. To create a sufficient system for edge guide control, you’ll need to install three basic products – an actuator, controller and sensor. These work together to detect and send signals for controlling the alignment of the web. There are several types of controllers, including pneumo hydraulic, analog and digital. There are also several types of actuators and sensors, which should be chosen based on the application, facility and type of web material being guided.

Web guiding systems are a must for accurate alignment, whether guiding thick metal strips, very thin plastics or even wide/narrow webs. Carotron, Inc. manufactures the Edge Guider Model EG1000-000. This Edge Guider can handle up to 1/2-horsepower 90 VDC armature P.M. motors and 1-horsepower 180 VDC P.M. motors. If you need to develop a web guiding system that works seamlessly with your edge guiding application, Carotron’s engineers are always available to help you determine the right products and how to go about installing them.

When buying a motorized potentiometer, it’s important to select one that features the INCREASE and DECREASE buttons that make it easy to slowly rotate the motor in either direction. These potentiometers have multiple buttons that can be wired in parallel, thus allowing an adjustment in multiple areas for increase or decrease.

Today, you can purchase motorized potentiometers that are easy to mount on the motor thanks to “Din-rail mountable” enclosures. Din-rail mountable potentiometers cut down on installation time and costs while providing an easy-to-use module with upgraded features. One example is the MOP250-000 (Electronic Motor Operated Potentiometer Module) by Carotron, Inc. It has dedicated INCREASE and DECREASE pushbuttons that can be pushed simultaneously to reset the potentiometer. The operator can open or close the enable input to force the unit to ramp down or back up. There’s also an EXTERNAL REF input to scale an external signal if necessary.

Carotron makes multiturn MOPs as well to adjust the settings for ACCEL, DECEL, BIAS and GAIN. Speak with a skilled engineer if you’re unsure of the type of motorized potentiometer you’ll need. These are great units for a variety of industrial operations, and they are affordable and reliable.

In a fast-paced plant or facility, installing industrial motor components and controllers can cause real headaches. Motor controls often come in a manufacturer’s kit that might include various tools, accessories, screws, circuit boards, etc. to use for installation. Most facility managers don’t want to take time out of the production schedule to install such units, so the task might get put on the back burner for months!

Thankfully, manufacturers like Carotron, Inc. are creating din-rail mountable controllers that can be installed in no time. These are circuit cards or boards that are already assembled on a piece of hardware, or a mount, that’s ready to be installed onto your motor or equipment. The mounts are usually standardized, but some manufacturers can customize your product if needed. With din-rail mountable controls, the manufacturer has taken an extra step to structure an all-in-one package so you can get it connected quickly.

Some product examples (from Carotron) include din-rail mountable Electronic Relay Modules, Frequency to Voltage Modules, Voltage to Frequency Modules, and others. Check with a skilled engineer to get help in making your selection for motor control products. You’ll find that din-rail mountable devices are real time and money savers!

If you’re trying to increase productivity in your converting facility while maintaining a high web material quality, consider implementing web tension control processes to measure and control tension. As a web of film, foil, paper, plastic or other material leaves one roller and is pulled by another, tension forms on either one end of the web or the other. If this tension is not somehow controlled, whether digitally or manually, the material will become damaged or distorted. Thankfully, there are a number of tension controllers on the market to help with this process. Digital controllers measure the tension and convert it to a signal so the machinery can be adjusted to the initial set point or reference, which is usually set by the machine’s operator prior to starting a run. This keeps the material tension at an even level during the entire process, thus reducing loss of material during a run.

If your facility has machinery that uses an older DC motor, there are manufacturers that still produce innovative microcontrollers to help with web tension control needs. Look for new digital microcontrollers that can be used for multiple applications. Carotron, Inc. manufactures these types of controllers and many other control products. You can speak with an engineer directly to determine the best web tension control product for your application. From Din-Rail mountable controls to full-feature DC and AC drives, it’s easier than ever to promote smooth operation throughout your web handling facility!

If you own or manage a company that operates film/web processing machinery, then you probably understand the importance of having high quality linear actuator controllers. These can be used to control and guide all types of material, from very thin plastic film to very thick metal strips. They can control webs that are wide or narrow. The types of applications that can benefit from edge guiding control include blown film processes, gravure printing, slitting, extruders, flexo printing, etc. With a linear actuator controller, loss of material can be reduced to a minimum, and the product can be processed using the highest standards. This equals cost and time savings for all involved!

The controller works by calculating the difference for the given position, and then controls the actuator accordingly. The actuator is the component that actually guides web or film material back to the proper position. This makes it possible to control the film as it goes through various stages, while changing its shape and size. If you’re not sure what type of linear actuator controller you’ll need, contact a manufacturer to speak with a representative about your needs. Carotron, Inc., a motor control manufacturer, offers one-on-one consultations with qualified engineers to guide you through the edge guiding and control process.

Industrial facilities that handle production processes such as coating, printing, slitting, winding and unwinding, and other similar functions use tension load cells to get an accurate weight on loads. Tension is measured by the tension load cells and then converted to a proportional electrical signal. Once a signal has been created it is sent to a load cell amplifier or signal conditioner. The signal conditioner then converts the signal into torque or speed for the motor drive or brake, so the operation will maintain accuracy throughout the operation.

Without tension load cells, constant changes in temperature, material tension, material shape and consistency and other factors would affect the overall process and put strain on the machinery or motor being used. When ordering tension load cells, it’s important to make sure they can withstand extremely high overloads without damage. Carotron, a manufacturer of motor control products, makes LVDT Tension Load Cells (LCS01), which can handle 100-to-1 overloads without risking failure to the structure. Check out brochures, manuals and other data about the tension load cells you’re considering, or contact the manufacturer directly to speak with a sales engineer about your facility’s tension and signal conditioning needs.

AC solid state starters provide a “soft start” for heavy duty AC motors that are often used in factories, printing facilities, food and product distribution centers, and similar environments. And though all soft starters offer a number of benefits, there’s one type in particular that goes a step further. AC solid state starters with a built-in or integrated bypass contactor provide space savings as well.

How does it save space? Because of the built-in contactor, a smaller enclosure can be used for the starter (such as NEMA 12 enclosures). This feature also simplifies installation when trying to install the motor starter in a tight space. The starters have an easy-to-implement prewired design, so companies can enjoy time and money savings as well! Of course, there are still the usual benefits of a soft starter, such as emergency starting across the line, less wear and tear on motors, and the option to be used in custom starter applications.

Industrial components and motor control products that require Master/Slave (client and server) communication between two or more devices often use Modbus (R) protocols. The Modbus (R) RTU (RS-232 or RS-485) is the most widely accepted protocol in industrial facilities because it is reliable and easy to implement and use. Another benefit is Modbus (R) protocols can be implemented in mutliple settings, whether between sensors, with multiple devices, between instruments, or even for monitoring purposes.

One feature that makes Modbus (R) RTU protocols so diverse and popular is that they have a simple design for transmitting messages between server and client. These use the basic command and response system to ensure that machinery and computers can work efficiently without error. Compare Modbus (R) protocols with other newer client/server protocols on the market to learn of the differences. You’ll find that in many cases, the simplicity of the RTU modules is all you’ll need!

When your industrial operation depends on daily production for profits, you can’t afford to have unnecessary downtime due to faulty equipment or older motors and drives that are working poorly. Developing a regular preventive maintenance schedule on heavy duty motors and equipment can cut downtime by a great percentage. Motors, motor drives and other equipment are continuously being exposed to debris and dust particles and sometimes liquids, oil, steam, etc. If you don’t maintain and clean this equipment on a regular basis, it will eventually stop performing at its maximum capacity.

Develop a preventive maintenance program that involves qualified personnel as well as those employees who operate the equipment most often. This can help prevent future losses in profit and time by ensuring that the equipment is well taken care of. It’s a fact that all motors and industrial motor control products will eventually wear out or break beyond repair…but why speed this process along by ignoring preventive maintenance? You can easily view PDF manuals online and/or contact a qualified engineer to find out the best way to maintain your facility’s heavy duty DC or AC motors and equipment.

When searching for motor control products, look for motor control PDF files that contain brochures, instructions manuals, etc. to help you find the best product. Industrial motor control usually consists of trying to find the right products at an affordable price. But one thing you don’t want is to order a DC or AC motor drive that doesn’t fit properly or that doesn’t have all the features you need. You’ll waste time and money in doing so. You can also face compatibility issues if your plant or store has machinery that uses older DC motors. With these motors, you don’t necessarily have to replace the actual motor (unless is it irrepairable). You do, however, need to make sure the DC drive will fit properly with the settings, sizing, etc. Retrofit DC drives are available through some manufacturers (such as Carotron, Inc.) that can be fitted to older DC motors.

Whatever your choice in moving forward with your motor control needs, reading the motor control PDF files from the manufacturer’s website can be of great assistance. The files may contain brochures and manuals featuring photos, application examples, dimensions and connections, model ratings, special features and more. Get accurate measurements and voltage requirements. View diagrams/drawings of the installation methods and more. Motor control PDF files are downloadable through your browser and can be viewed by simply clicking a link with most computers. So use this valuable resource to narrow your search for industrial control products.

DC motors are utilized in many industrial settings that require variable speed and torque applications. Because of the simplistic design and ease of control with DC motors, many companies choose to order control products for their DC motor rather than replace it with a newer type motor (AC motors). DC motors use a permanent magnet field, which is produced either using permanent magnets or electro-magnetic windings. A common problem experienced with DC motors is “loss of field.” This can cause the motor to accelerate to its fastest speed (based on loading speed), but can permanently damage the motor, especially if this happens with a lightweight load.

Motor control manufacturers such as Carotron, Inc. can provide Field Economy Options (field supply assembly) for motor field current reduction. The reduction occurs after an adjustable time delay. This reduces excessive heating that can occur in the motor windings when the motor remains idle for an extended period of time. The benefits? Motor field current reduction minimizes the build up of moisture, speed drift, and any problems that can occur during a cold start-up. This particular Field Economy OPtion can be used with a 3 phase input DC motor control product.

Do you need a product that provides accel/decel functions without isolation? Check with motor control manufacturers such as Carotron, Inc. for high precision cards that can handle a variety of industrial applications for harsh environments. One example is the Accel Card (accel/decel) and Power Supply Card, Model C11698-000. It can handle various applications for industrial motor control. Acceptable sources for this accel card are inputs up to 10VDC maximum. This supply allows the input signal to be sourced from a 1,000 to 10,000 ohm potentiometer. This accel/decel card comes with a contact closure, which enables the card’s circuit and allows the reference to accelerate to a level that is set by the input voltage or potentiometer. If you need an accel card for accel/decel applications and power supply card for industrial applications, you can view the instruction manual, dimensions/connections, specs, application examples and more free of charge at the manufacturers website, Carotron, Inc.

The right AC and DC motor drives can provide the precision control necessary to keep certain industrial machinery and other motor-driven products working smoothly. Carotron, Inc., a manufacturer of DC and AC motor drives, provides a free motor control tutorial at the company’s website to give insight into subjects such as torque control, velocity control, tachometer feedback, armature feedback, V/F control, V/F with encoder or tachometer feedback, open loop and closed loop, and regeneration. With their extensive Applications Guide, Carotron provides motor control basics and the most popular applications for their motor drives.

In industrial motor control applications, isolation issues can wreak havoc for DC and AC drives that are not isolated. The problem occurs when high fault currents go through circuitry that is not designed to handle them, and there are noticeable results. There might be blown fuses, smoke, burnt components, loud noises, printed circuit copper foil traces, etc. One way to eliminate driver isolation issues is to install a motor drive that isolates the voltage by design. Carotron, Inc. manufacturers a number of motor drives with this feature, such as the Elite, Elite Pro, Choice and Blazer Series. The company also offers a free motor isolation guide at its website for end users as well as distributors that are trying to help their clients solve machine isolation issues.

With retrofit DC drives such as the Elite Pro by Carotron, Inc., an obsolete drive replacement can save the day and drastically reduce downtime! For example, Elite Pro dc drives are the perfect retrofit products for brands such as Reliance Electric, Fincor, Saftronics and Emerson. Carotron works closely with its distributors and gives personalized customer service to all clients. So retrofit dc drives for these brands are available with just a phone call.

Some DC motor drives can deliver variable or adjustable speed control. The drives are used as an interface between a motor and its controller. Drives must be designed to match the power and voltage levels (control signals) as well as the digital or analog signal types. DC drives are used for amplification and power conversion. They also produce sequencing for waveform signals. Typical applications for these types of drives may include speed and torque control, tension control, web tension, wire drawing, extruder, paper converting, textile applications and more. A company that manufactures DC motor drives called Carotron serves motor control distributors around the world with innovative products such as Blazer Series, ADP100 Series, Elite and Elite Pro, Choice Series 5, Trooper Series and others.
