1. A control device for a rotating electric machine, the control device being configured to control an inverter configured to apply a voltage to each phase winding of a rotating electric machine, to thereby control, for the each phase winding, a current to be supplied to the each phase winding, the control device comprising:
control circuitry configured to calculate a voltage command value to be applied to the each phase winding so that a phase difference between harmonic components of the same order in a radial magnetic flux density and a circumferential magnetic flux density of an air gap portion between a stator core and a rotor core of the rotating electric machine becomes a phase difference target value determined in advance, and to control the inverter in accordance with the calculated voltage command value.
