Can high frequency inverters perform rotational induction

The high frequencies in the switching and transient spikes are also induced into the rotor and build up a voltage potential between the rotor and stator. This voltage is dissipated by arcing through the ball bearings. The inverter, also referred to as a variable frequency drive (VFD), tarts by converting an AC input, whether single. . Early inverters caused significantly higher temperature rise in the motor, and mismatched could easily burn out the motor. It is time to design motors. . The best method of speed control must therefore provide for continuous smooth variation of the synchronous speed, which in turn calls for variation of the supply frequency. A complete speed control scheme which includes tacho (speed) feedback. .  fN : Flux weakening:  ~ 1/ fs : Iron & copper losses constant; frequency limit: breakdown/rated power reaches 160%. 50 Hz to 87 Hz for constant torque.
