    摘要: A rotary electrical device includes a rotor configured to be rotatable; and a stator disposed in a radial direction of the rotor to surround a rotation axis of the rotor. The stator includes a plurality of stator units that are stacked in an axial direction of the rotor. Each of the stator units includes a winding, a stator core that surrounds the winding, and one or more claw magnetic poles that protrude radially toward the rotor from each of two end portions in an axial direction of the stator core. The rotor includes a magnet that radially faces at least a portion of any of claw magnetic poles of the stator at a predetermined rotation position. At least one of magnet end portions in an axial direction of the magnet protrudes further in the axial direction than all of the claw magnetic poles of the stator.

    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 brushless motor includes a first rotor core, a second rotor core, and a field magnet member. 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 with a first rotor core, a second rotor core, a field magnet, and an interpole magnet is provided. The first rotor core has a first core base and a plurality of first nail-shaped magnetic pole parts that extend in the axis direction from the outer circumference section of the first core base. The second rotor core has a second core base and a plurality of second nail-shaped magnetic pole parts that extend in the axis direction from the outer circumference section of the second core base. The field magnet is magnetized along the axis direction and makes the first nail-shaped magnetic parts function as first magnetic poles and the second nail-shaped magnetic parts function as second magnetic poles. The interpole magnet is arranged between the first nail-shaped magnetic parts and the second nail-shaped magnetic parts. The interpole magnet has the same polarity as the first and second nail-shaped magnetic pole parts, in the sections where same face the first and second nail-shaped magnetic pole parts.
