Reply to "Williams Can Motor Heat"

Motors don't run at a constant voltage with command control.  AAMOF, the voltage the motor sees with command or conventional at the same speed should be pretty much the same voltage, think about it.   I seriously doubt the waveform has that much to do with how hot the motor gets.  The motor is a pretty large inductance and swamps out most issue with the non-sinusoidal waveform.  The analysis I've seen attributes at most a few percent energy loss over pure DC with a PWM drive.
