What is Regenerative Energy? When a motor turns faster than the commanded speed as set by its AC variable speed drive, the motor in effect acts as a generator. An example of this would be the control of an elevator car as it descends. With the help of gravity, the load will readily lower. In fact...

Special algorithms make ac induction motors respond like variable-speed dc motors for fast PID control. The rotating speed of ac induction motors is determined by the frequency of ac applied to the stator, not the applied voltage. However, stator voltage must also drop to prevent excessive current...
