摘要： A motor includes a motor case, and a rotor and a stator, which are disposed in the case. The case has a tubular portion, a front cover mounted to an axial end of the portion, and a rear cover mounted to the other axial end of the portion. The rotor has a rotary shaft and the stator includes a plurality of teeth, which extend toward a central axis of the shaft and are circumferentially disposed at equal intervals. Between each circumferentially adjacent pair of the teeth, a slot extending toward the axis is formed. In each slot, a U-shaped segment is inserted in parallel with the axis. The distal ends of the segments projecting out from the slots are electrically interconnected, thereby forming an SC coil including the segments disposed circumferentially. The SC coil includes a receiving terminal, and the terminal includes leads extending in parallel to the axis.

摘要： A rotor of an embedded magnet type motor has a plurality of magnets forming magnetic poles, the number of which is represented by P. A rotor core includes first accommodation holes, the number of which is represented by P/2, extending in a radial direction, and V-shaped accommodation holes, the number of which is represented by P/2, having a V shape protruding outward in a radial direction. The first accommodation holes and the V-shaped accommodation holes are alternately arranged in a circumferential direction. The V-shaped accommodation holes include a second accommodation hole and a third accommodation hole corresponding to two straight lines forming the V shape. The first accommodation hole is adjacent to the second accommodation hole at one side in the circumferential direction, and is adjacent to the third accommodation hole at the other side. A plurality of magnets include a first magnet arranged in the first accommodation hole, a second magnet arranged in the second accommodation hole, and a third magnet arranged in the third accommodation hole. The first magnet and the second magnet form one magnetic pole. The first magnet and the third magnet form another magnet pole. Accordingly, it is possible to achieve a high torque while suppressing an increase of the number of parts of the embedded magnet type motor.
