Abstract: The present disclosure relates to a motor assembly and a method for controlling the motor assembly. The motor assembly is characterized by comprising: a stator having a plurality of slots; a first coil and a second coil isolated from the first coil, the first and second coils being wound on each of the plurality of slots such that three-phase alternating currents are applied thereto; a rotor rotated by rotation magnetic fields generated by the first coil and the second coil; a first inverter unit for controlling the three-phase alternating current which is applied to the first coil in order to generate the rotation magnetic field; and a second inverter unit for controlling the three-phase alternating current which is applied to the second coil in order to generate the 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.
