ABSTRACT:
A motor controller for an axial-gap motor permits a reduced size of the entire system of including a drive circuit and a power source of the motor, reduced cost, and higher reliability to be achieved by controlling the energization mode of the motor. The motor controller has a torque command determiner which inputs a first DC voltage to a first inverter at least either when a rotor is at a halt or when the number of revolutions of the rotor is a predetermined number of revolutions or less, supplies a field axis current for changing the magnetic flux of a field of the rotor to a first stator from the first inverter such that the amount of energization is temporally changed, converts an induced voltage developed in a second stator by the supplied field axis current into a second DC voltage by a second inverter, and outputs the second DC voltage, thereby charging a second battery.
