The first rotor core includes primary projecting pieces arranged along a circumferential direction at equal intervals. The second rotor core has the same shape as the first rotor core, and includes secondary projecting pieces arranged along the circumferential direction at equal intervals. The secondary projecting pieces are positioned between the primary projecting pieces that are adjacent to one another in the circumferential direction. The field magnet member is arranged between the first rotor core and the second rotor core. The field magnet member is magnetized along an axial direction to generate primary magnetic poles in the primary projecting pieces, and generate secondary magnetic poles in the secondary projecting pieces. A rotor includes the first rotor core, the second rotor core, and the field magnet member.

摘要： A rotor is provided with a first rotation member having a plurality of first claw poles in a circumferential direction and a second rotation member having a plurality of second claw poles in a circumferential direction. By of fitting each second claw pole in a cutout portion between first claw poles and by fitting each first claw pole in a cutout portion between second claw poles, the first rotation member and the second rotation member are assembled to each other. At least either one of the first rotation member and the second rotation member is formed of a magnet. Based on a magnetic field generated by the magnet, the first claw poles and the second claw poles have alternating north poles and south poles in the circumferential 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： An axial gap motor rotor opposes a stator in an axial direction. The axial gap motor rotor includes a rotor core and a magnet. The magnet is arranged on the rotor core. The magnet is configured so that one axial end includes magnetic poles that alternately change in a circumferential direction. The rotor core includes a base, which is located at a center in a radial direction, and radial extensions, which are extended from the base outward in the radial direction and arranged in the circumferential direction. The magnet is configured to at least partially overlap the radial extensions in the axial direction. The radial extensions are located to include a boundary of adjacent ones of the magnetic poles in the circumferential direction.

摘要： A motor including a stator and a rotor. The stator includes teeth and windings. Each tooth has a distal portion defined by a radially inward side of the stator. The rotor, which is arranged inward in the radial direction from the stator, includes a rotor core, magnets, and salient poles. Each salient pole is separated by a void from the magnet that is adjacent in the circumferential direction. The distal portion of each tooth is longer than a radially outward side of each 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.
