摘要： A stator unit including a coil in which a distance between an m−1-th turn and an m-th turn is wider than each distance in a first turn to the m−1-th turn. The m+1-th turn is disposed between the m−1-th turn and the m-th turn. Further, in a cross-section perpendicular to a central axis and passing a tooth, an angle between a line segment connecting respective centers of the m+1-th turn and the m−1-th turn and a line segment connecting respective centers of the m+1-th turn and the m-th turn is about 120° or more. With this structure, bulging in a circumferential direction of the coil adjacent to an inner peripheral portion of the tooth can be suppressed and a clearance can be secured between adjacent coils such that the number of turns of the coil can be increased.

摘要： A motor having a busbar unit which is accommodated in a housing along with an armature includes a relay wherein the connection between the armature and the relay is secured. By virtue of such a configuration, reliability of the connection between the armature and the relay is improved. In the busbar unit, a plurality of first busbars and a plurality of second busbars each having a substantially arcuate shape are arranged so as to be circumferentially spaced apart from one another. The first busbars do not overlap with the second busbars in the axial and radial directions thereby reducing the dimensions of the motor in the axial and radial directions.

摘要： A rotor unit includes a rotor core made of laminated steel sheets that are vertically laminated, and a holder made of resin. The rotor core and the holder are fixed together through insert molding. For this reason, the process of manufacturing the rotor core and the holder is shortened. Additionally, in the outer peripheral surface of the rotor core, a portion of resin that defines the holder is present between the plurality of steel sheets that defines the rotor core. For this reason, the fixing strength of the rotor core and the holder improves. Additionally, since a separation between the rotor core and the holder is prevented, magnets can be easily press-fitted.

摘要： A motor includes a sensor which magnetically detects an angular position centered about a central axis of a rotor core with respect to an armature. The sensor preferably includes a yoke which has a substantially annular shape, is made of a magnetic material, is arranged substantially perpendicularly to the central axis and is affixed to a shaft, a sensor magnet affixed at the yoke, a magnet cover which covers a surface of the sensor magnet other than a portion in contact with the yoke, a first Hall element and a second Hall element both of which are arranged facing in an axial direction a surface of the sensor magnet opposite from a surface thereof at which the yoke is arranged. Since the sensor magnet is covered by the yoke and the magnet cover, even when the sensor magnet is damaged, the damaged sensor magnet is prevented from damaging other components of the motor. By virtue of such configuration, the reliability of the motor is improved.
