Abstract: A rotor having an axial direction includes at least a pair of rotor cores arranged in the axial direction, and a field magnet located between the rotor cores and magnetized in the axial direction. Each of the rotor cores includes a plurality of claw poles extending in the axial direction. Each of the rotor cores includes a magnetic flux controlling section, which appropriately causes a magnetic flux to flow to the claw poles.

Abstract: A rotor includes first and second rotor cores, a field magnet, and an annular magnet. The first and second rotor cores each include a core base and core magnetic poles. The core magnetic poles are provided on an outer peripheral portion of the core base at equal intervals. The core bases are faced with each other. The core magnetic poles are alternately arranged in a peripheral direction. The annular magnet is a resin molding product including a magnetic pole magnet portion and an inter-pole magnet portion. The annular magnet has a non-contact portion not in contact with the first and second rotor cores. A gate mark portion in injection molding of the annular magnet is arranged in the non-contact portion.

Abstract: A motor includes a stator, a rotor, and a case. The stator includes a stator core and windings. The rotor is provided inside the stator. The rotor includes first and second rotor cores and a field magnet. The first and second rotor cores each includes a core base and claw-shaped magnetic poles. The core bases are opposed to each other and the claw-shaped magnetic poles of the first and second rotor cores are alternately disposed in a circumferential direction. The field magnet is disposed between the core bases in the axial direction. The field magnet is magnetized in the axial direction so as to cause the claw-shaped magnetic poles of the first rotor core and the second rotor core to function respectively as first magnetic poles and second magnetic poles. At least part of an end part of the case in the axial direction is made of a non-magnetic body.
