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.

摘要： A rotor includes a first rotor core, a second rotor core, a permanent magnet and a resin layer. The first rotor core includes a first core base and first claw-shaped magnetic poles arranged at equal intervals on a peripheral portion of the first core base. The second rotor core includes a second core base and second claw-shaped magnetic poles arranged at equal intervals on a peripheral portion of the second core base. The first rotor core and the second rotor core are combined with each other so that the first and second core bases are opposed to each other and the first and second claw-shaped magnetic poles are alternately arranged in the circumferential direction of the rotor. The permanent magnet includes at least a main field magnet. The main field magnet is located between the first and second core bases in the axial direction, and is magnetized in the axial direction. The main field magnet causes the first claw-shaped magnetic poles to function as first magnetic poles, and causes the second claw-shaped magnetic poles to function as second magnetic poles. The resin layer covers at least a portion of a surface of the permanent magnet.

摘要： A rotor of a motor includes first and second rotor cores, a field magnet, and a commutator magnet. The first and second rotor cores each include a core base and a plurality of claw poles. The claw poles of the first rotor core and the claw poles of the second rotor core are alternately arranged in a circumferential direction. The field magnet is located between the core bases. The field magnet is magnetized in an axial direction so that the claw poles of the first rotor core and the claw poles of the second rotor core function as different magnetic poles in the circumferential direction. The commutator magnet is located on an outer circumference of the field magnet around the claw poles. The commutator magnet is magnetized so that surfaces having the same polarity face each other between the claw poles and the commutator magnet.
