摘要: 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.

摘要: A rotor comprises a rotor core, a plurality of magnetic poles arranged in a circumferential direction of the rotor core, a plurality of salient poles and a plurality of auxiliary magnets each of which is disposed between the magnetic pole and the salient pole is provided. Each magnet pole has a field magnet pole that serves as a first magnetic pole, wherein the field magnet is a main magnet. Each salient pole is integrally formed with the rotor core between the two adjacent magnetic poles. Each salient pole serves as a second magnetic pole. The pole of the second magnetic pole is opposite from that of the first magnetic pole. The auxiliary magnet generates magnetic flux in a circumferential direction of the rotor core so that the magnetic pole and an opposing pole of the auxiliary magnet have the same polarity and the salient pole and another opposing pole of the auxiliary magnet have the same polarity.

摘要: A rotor includes first and second rotor cores, a field magnet, interpole magnets and holding members. The first and second rotor cores each have claw-like magnetic poles arranged in the circumferential direction in an outer periphery of a core base at even intervals and formed to protrude radially outward. The field magnet is placed between the core bases in the axial direction of the rotor and magnetized in the axial direction to cause the magnetic poles of the first and second rotor cores to function as first and second magnetic poles, respectively. The interpole magnets are each arranged between a circumferentially adjacent pair of the magnetic poles and magnetized in the circumferential direction so as to have the same polarity as the magnetic poles, which are opposed thereto in the circumferential direction. The holding members hold the interpole magnets to restrict radially outward movement of the interpole magnets.

摘要: A rotor includes a field member arranged between a first core base of a first rotor core and a second core base of a second rotor core in the axial direction. When magnetized in the axial direction, the field member causes primary claw-shaped magnetic poles to function as primary magnetic poles and secondary claw-shaped magnetic poles to function as secondary magnetic poles. The field member is formed by placing a plurality of members one over another in the axial direction.
