  • Patent number: 10014746
    Abstract: In a rotary electric machine, wound wires are connected to a first terminal and a second terminal. Circuit terminals that are configured from a conductive metal other than aluminum, and the first terminal and the second terminal that are configured from a metal with a principal component of aluminum are joined together inside a circuit chamber that has high water resistant properties. Corrosion is accordingly suppressed at join sites of the circuit terminals with the first terminal and the second terminal. There is therefore no need to coat the join sites with for example a sealing material in order to suppress corrosion at the join sites. Good electrical continuity is accordingly enabled between the circuit terminals and the wound wires while suppressing an increase in costs, even when the wound wire is configured from a metal with a principal component of aluminum.

  • Patent number: 9882439
    Abstract: A rotor includes magnetic pole portions and first and second ferric core portions. The first and second ferric core portions are each located between magnetic pole portions in the circumferential direction of a rotor. A first gap is formed between the first or second ferric core portion and a magnetic pole portion at a first circumferential side. A second gap is formed between the first or second ferric core portion and the magnetic pole portion at a second circumferential side. The first gap has a smaller width than the second gap at the first ferric core portion. The first ferric core portion is inclined toward the first circumferential side. The first gap is larger than the second gap at the second ferric core portion. The second ferric core portion is inclined toward the second circumferential side.

  • Patent number: 8232703
    Abstract: 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.

    Abstract: 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.

    Abstract: 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 ?a of each first gap and the angular width ?b of each V-shaped gap are determined to satisfy the expression: 0.60<?a/?b<1.60.

  • Patent number: 7705504
    Abstract: 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.
