摘要： A miniature motor having a plurality of commutator segments with commutator terminals which are connected to rotor windings. The commutator terminals are disposed on an insulating cylinder which is fixedly fitted to a motor rotating shaft, and a spark-quenching resistor connects each of the commutator segments. This resistor is a disc-shaped electrically conductive rubber ring which is fitted to the insulating cylinder so that the end face of the disc-shaped ring comes in contact with the commutator segment and commutator terminals and is brought into intimate contact with the commutator terminals by heating.

摘要： A bearing device for miniature motors comprising a stator formed by fitting an end plate to an open end of a housing formed into a bottomed hollow cylindrical shape. A rotor rotatably supported by bearings is provided on the housing and the end plate. A bearing retaining body is provided formed of a resin material into a basket shape. The bearing retaining body has such a construction that a flange and a bottom member, both formed into a ring shape, are connected by a plurality of axially extending and circumferentially disposed connecting members. A plurality of axially extending support columns are disposed in the circumferential direction on the inner edge surface of the bottom member. The bearing retaining body is fitted to a retaining part provided on the housing and/or the end plate, and a ball bearing is supported via the supporting claims.
