摘要： Magnetic poles are arranged such that the N pole and the S pole alternate in a circumferential direction. Two N poles face each other with an interval of 180° therebetween, and two S poles face each other with an interval of 180° therebetween. Each of the magnetization center of a North magnetic pole and the magnetization center of a South magnetic pole is positionally shifted from the center position between the magnetization centers of two magnetic poles of the other polarity located on opposite sides of the North or South magnetic pole. The magnetization centers of the magnetic poles are disposed in such a manner as to be positionally shifted from geometric centerlines. Brushes are disposed along the respective geometric centerlines. The magnetization centers of two adjacent magnetic poles are positionally shifted toward or away from each other by the same shift angle α with respect to the respective geometric centerlines.

摘要： A motor comprises a stator, a rotor being arranged in and facing said stator, an urging member which urges a center rotation shaft of the rotor in an axial direction, and a bearing which rotatably holds the rotor at a predetermined position while receiving an urging force by the urging member. The stator is provided with a resin coil bobbin made by insert molding and integratedly assembled with a metal stator core. The stator core is arranged in and faces the rotor and forms a magnetic circuit therewith. The coil bobbin is arranged at the end side of the rotor. A holding portion is integratedly formed, the holding portion holds the urging member so as to urge the rotor to the bearing side. A curling base is fitted in. The curling base is formed such that a flat plate-shaped metal plate is rounded from outside of a winding wound by the electric coil bobbin in the circumference direction of the stator.
