摘要： In a motor, a magnetic sensor is provided on the lower surface of a substrate disposed above a magnetic sensor. On an upper surface of the substrate, a plate-shaped magnetic member is disposed at a position axially overlapping the magnetic sensor. The substrate and the magnetic member are fixed to each other at a plurality of fixing positions by axial tightening. On the upper surface of the magnetic member, a rib extending to connect the vicinity of one fixing position and the vicinity of another fixing position is provided. Flexure of the magnetic member is significantly reduced and prevented by this rib. For this reason, the direction of the magnetic flux of a magnet is concentrated on the magnetic sensor side. As a result, detection accuracy of the magnetic sensor is significantly improved.

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 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.

摘要： A bus bar secured to a stator in an electric motor in a preferred embodiment according to the invention includes four wiring boards, which are arranged perpendicularly to a center axis at intervals in a direction toward the center axis, and a resin portion for covering the surroundings of the four wiring boards by injection molding. Resin passing holes, through which a resin flows when the resin portion is molded, are formed at each of the wiring boards. When the bus bar is molded, the resin is injected into a resin molding die in a state in which the four wiring boards are supported by supporting pins disposed inside of the die. The resin flows to and fro between a space defined between the die and the wiring board and a space defined between the adjacent wiring boards.
