Abstract

A motor assembly may include a stator; a first inverter unit for controlling a three-phase alternating current which is applied to a first coil in order to generate a rotation magnetic field; and a second inverter unit for controlling a three-phase alternating current which is applied to a second coil in order to generate a rotation magnetic field. Control signals for turning on and off the three-phase alternating currents applied to the first coil and the second coil are generated so as to be left-right symmetric by the first inverter unit and the second inverter unit during a preset switching cycle.
