Frequency Inverters – Vector Drives
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.
