WebThere are several different methods useful for causing an AC induction motor to brake, or slow down: DC injection. Dynamic braking. Regenerative braking. Plugging. DC injection uses the technique of energizing the stator windings with low-current DC instead of high-current AC as is the case when the motor runs. WebAug 8, 2015 · Myth No. 4: You can run a motor at any speed with a VFD. The beauty of using VFDs is that they can vary both their output voltage and output frequency. Their ability to run the motor slower and faster than its nameplate-rated speed is part of why they are specified so often. Take the motor out of the equation, and this myth is actually true.
