    Abstract: There is provided a motor including a rotor and a stator arranged outside the rotor in the radial direction. The rotor includes a rotor core, a plurality of magnets arranged at equal intervals in the circumferential direction of the rotor core and functioning as one magnetic pole, and salient poles integrated with the rotor core, each arranged between adjacent magnets and at a distance from the magnets. The salient poles function as the other magnetic pole. A stator has a stator core having a plurality of teeth extending in the radial direction of the stator and arranged at equal intervals in the circumferential direction, and multi-phase coils attached to the teeth. The plurality of salient poles are arranged to have center portions arranged at equal intervals in the circumferential direction, and each have an outer surface extending in the circumferential direction in a range of a predetermined opening angle having an axis of the rotor as a center. A first opening angle serving as an opening angle of an outer surface of a first salient pole is different from a second opening angle serving as an opening angle of an outer surface of a second salient pole.

    Abstract: A controller for use with a motor including a stator, around which three-phase coils are wound, and a rotor, which includes a magnet functioning as a first magnetic pole and a salient pole of a core functioning as a second magnetic pole. The controller supplies the three-phase coils with excitation currents having a predetermined phase difference from one another to drive and rotate the rotor. The controller includes a current adjustment unit that adjusts a fundamental wave current using high-order currents for third order and ninth order components in a q-axis to reduce torque ripple. The excitation current is generated based on the fundamental wave current adjusted by the current adjustment unit.
