    摘要： A rotor of an embedded magnet type motor is disclosed. A rotor core of the motor includes first accommodation holes and V-shaped accommodation holes. The first accommodation holes extend in radial directions, and the V-shaped accommodation holes protrude radially outward. The rotor core has grooves at positions corresponding to the first accommodation holes on the outer periphery of the rotor core. Each groove has a width as a dimension in the circumferential direction when viewed from the axial direction. Each first magnet has a width as a dimension in the circumferential direction when viewed from the axial direction. The width of the grooves is larger than the width of the first magnets.

    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 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.
