The motor rate can be differed from absolutely no rpm with to typically % of its complete rated rate whilst as much as 150% rated torque can be accomplished at lowered rate. Due to the high-speed changing frequencies utilized in PWM inverters, all variable regularity drives generate shaft existing in AC electric motors. The changing frequencies of insulated-gate bipolar transistors (IGBT) used in these drives create voltages on the motor shaft during normal procedure via electromagnetic induction.
