    • 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.
