The difference between PWM and general motors
Frequency conversion motor adopts "special inverter induction motor + frequency converter" way of ac speed regulation, make the mechanical automation degree and greatly improved the efficiency of production equipment miniaturization, increase comfort, is to replace the traditional mechanical control and dc speed control scheme.
PWM motor is frequency conversion motor, that is, the inverter output waveform is not filtering after PWM wave, ordinary motor generally as a standard, usually sinusoidal waveform, if use frequency converter drive, also need to add after the inverter output filter circuit, or general motors can not stand, fever is serious, but also is frequency conversion motor PWM motor is ok.
