摘要： This motor includes a two-layer rotor, a two-layer stator and a control unit. An A-phase rotor includes a pair of rotor cores and a field magnet. A B-phase rotor includes a pair of rotor cores and a field magnet. An A-phase stator includes a pair of stator cores and an A-phase winding. A B-phase stator includes a pair of stator cores and a B-phase winding. The control unit controls an A-phase input voltage applied to the A-phase winding, and a B-phase input voltage applied to the B-phase winding. The relative arrangement angle of the A-phase stator and the A-phase rotor relative to the B-phase stator and the B-phase rotor is set to an electrical angle of 90 degrees. The control unit applies a leading phase angle to the basic voltage waveforms of the A-phase input voltage and the B-phase input voltage, to set the energization width to at most 180 degrees.

摘要： A rotor with four axially stacked rotor cores, and a plurality of field magnets interposed between them. Each rotor core includes a rotor-side claw-shaped magnetic pole. Each rotor-side claw-shaped magnetic poles are respectively extending from and formed on each rotor core at equal angle intervals. Tip end surfaces of the first and third rotor-side claw-shaped magnetic pole abut against or are closely opposed to each other axially. Tip end surfaces of the second and fourth rotor-side claw-shaped magnetic poles abut against or are closely opposed to each other in the axial direction. The plurality of field magnets are magnetized in the axial direction such that the field magnets causes the first and third rotor-side claw-shaped magnetic poles to function as first magnetic poles, and cause the second and fourth rotor-side claw-shaped magnetic poles to function as second magnetic poles.

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.

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.
