Abstract

A system includes a three phase AC or brushless DC motor, an inverter and a controller. The inverter is electrically coupled to the motor. The controller is -electrically coupled to the inverter. The controller is configured to control the inverter to deliver a three phase pulse width modulated voltage to the AC motor, wherein the three phase pulse width modulation comprises a repeating two-cycle pattern.
