Intro to setting up, tuning a PM motor with a VFDMar 02, 2022
- Consider induction motors versus permanent-magnet motors.
- Examine VFD selection, programming, tuning for PM motor applications.
- Learn how to verify PM motor operation after VFD setup and auto tuning.
Induction motor (IM) and permanent magnet (PM) motor designs differ, including their use of variable frequency drives (VFDs). IM motors are designed to be able to run using across the line power to run at a constant speed. A PM motor is not designed to run across the line. A PM motor requires a VFD to provide the correct output to effectively operate the PM motor.
