ROTATING ELECTRIC MACHINE DRIVE SYSTEM

WIPO Patent Application WO/2019/012915

A1

This rotating electric machine drive system is provided with: a rotating electric machine (10) equipped with a rotor (12) in which each magnetic pole is constituted by a plurality of permanent magnets (22) and in which a salient pole portion (23) magnetically salient in the radial direction is disposed at the pole central portion lying between the plurality of permanent magnets in the magnetic pole, and with a stator (13) having a multi-phase stator winding (36) wound therearound; an inverter (41, 42) for supplying power to the stator winding; and a control unit (50) for controlling an energization current for the inverter. The control unit performs energization control for the stator winding in which a fundamental wave current having a fundamental frequency synchronized with the rotational speed of the rotor and a harmonic current having the third harmonic of the fundamental frequency flow through the stator winding, so that a stator magnetic field having a predetermined phase lead or phase lag with respect to the third magnetic field of the rotor is generated by the energization of the harmonic current.
