CONTROL DEVICE AND CONTROL METHOD FOR ROTATING ELECTRIC MACHINE

An object of the present invention is to control driving force and braking force of a motor while considering an SOC of a battery. A control device controlling a rotating electric machine including windings of a plurality of independent system. The rotating electric machine is controlled in: a first mode in which an AC current is energized to the windings of the plurality of systems to generate torque such that a combined magnetic field generated in the windings is greater than or equal to a predetermined value; and a second mode in which the AC current having a phase difference different from that in the first mode is energized to the windings of the plurality of systems, the combined magnetic field generated in the windings is made smaller than the predetermined value, and current greater than or equal to that in the first mode flows.
