An inverter having MxN arms is connected to a first motor having N groups of M phase coils and a second motor having M groups of N phase coils. At least one of the first motor and the second motor has as many teeth as the number of phases of the motor multiplied by an integer, and the MxN coils of the motor are wound around the teeth by equal to or more than two coils for each of the teeth. Drive points of the MxN coils of the first motor are connected to output points of the corresponding arms of the inverter. Drive points of the NxM coils of the second motor are connected to output points of the arms of the inverter, so that each of the N phase windings in each of the M groups of the second motor is connected to each of the N drive points of the first motor, the N drive points having the same phase. A controller feeds MxN pulse width modulation control signals to the inverter for the first motor and the second motor in a time-division manner, so that the first and the second motors are driven individually with the single inverter.
