Abstract
A switched reluctance motor system includes a switched reluctance motor, a rotor including a plurality of salient poles, a stator including a plurality of salient poles, coils of three phases wound around the salient poles of the stator, and an electronic control unit. The electronic control unit is configured to drive the switched reluctance motor in a pole configuration pattern of NSNSNS in which the salient poles of the stator that have different polarities are alternately arranged. The electronic control unit is configured to perform current waveform control when an excitation sound frequency of a given order coincides with a resonance frequency of the switched reluctance motor.
