    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 motor includes a housing having a substantially cylindrical shape accommodating therein a stator portion and a rotor portion. The housing includes a housing body having an opening at an upper side thereof, and a lid portion arranged between an armature and a sensor so as to close the opening of the housing body. Since the lid portion is made of a magnetic material and is arranged between the armature and the sensor, a magnetic effect on the sensor caused by a magnetic force generated at the armature is minimized. By virtue of such configuration in which the lid portion of the housing functions as a magnetic shield, the motor can be smaller in the axial direction compared with a configuration in which an extra layer of magnetic shield is arranged.

    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: 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.
