摘要： In a predetermined operating state of an electric motor 3 of an axial air-gap type, control is carried out as follows. A phase difference between an electric current supplied to an armature winding 13a of one of the stators 12a and an electric current supplied to an armature winding 13b of the other stator 12a is set so as to suppress a variation in an output torque of the electric motor 3, and electric currents having the phase difference are supplied to the armature windings 13a, 13b of the stators 12a, 12b. In an operating state other than the predetermined operating state, an electric current supplied to the armature winding 13a of the one of the stators 12a and an electric current supplied to the armature winding 13b of the other stator 12b are in a same phase. With this configuration, a variation in output torque can be suppressed only in an operating state where the variation in output torque of the electric motor is to be suppressed, and the output torque and the energy efficiency of the electric motor 3 can be enhanced sufficiently in the other operating states.
