    摘要： In an embedded magnet motor, radial magnets and first inclined magnets form north poles. The radial magnets and second inclined magnets form south poles. Core sheets each include preformed radial accommodating slots the number of which is expressed by P/2. Some of the preformed radial accommodating slots are short slots and the rest are long slots. The short slots are located at some parts of each radial accommodating slot along the axial direction. Radially inner ends of the short slots restrict the radial magnets from moving radially inward.

    摘要： An embedded magnet type motor is disclosed. The rotor core of the motor has radially extending first accommodation holes and V-shaped accommodation holes. Each V-shaped accommodation hole includes a second accommodation hole and a third accommodation hole. A first gap is formed in each first accommodation hole. The first gap is not occupied by the corresponding first magnet. A second gap is formed in each second accommodation hole. The second gap is not occupied by the corresponding second magnet. A third gap is formed in each third accommodation hole at a radially outer portion. The third gap is not occupied by the corresponding third magnet. Each second gap and the adjacent third gap form one V-shaped gap. The angular width θa of each first gap and the angular width θb of each V-shaped gap are determined to satisfy the expression: 0.60

    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.

    摘要： A first armature winding and a second armature winding each include a tubular member, a first conductor arranged in a radially inner side of the tubular member, and a second conductor arranged in a radially outer side of the tubular member. The first conductor includes a first coated portion, which is coated by a coating formed from an insulator, and a first wire connection portion, which is free from the insulator. The second conductor includes a second coated portion, which is coated by a coating formed from an insulator, and a second wire connection portion, which is free from the insulator. The first wire connection portion and the second wire connection portion are electrically connected to each other. A large output is obtained from a slotless motor including the first armature winding and the second armature winding.
