  • Rotor and motor
    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.

  • Embedded magnet type rotating electric machine
    Patent number: 7772735
    Abstract: A plurality of magnets are arranged in accommodating holes each extending in a radial direction. A rotor core is provided with an extension portion in a circumferential direction extending further outward in the circumferential direction with respect to the magnet from at least one of a radially outer end and a radially inner end in the accommodating hole, and a radial regulating portion regulating a movement of the magnet in the radial direction. The radial regulating portion extends in the radial direction so as to correspond to a center in the circumferential direction of the accommodating hole. The dimension in the circumferential direction of a portion of the radial regulating portion that is brought into contact with the magnet is smaller than the dimension in the circumferential direction of the magnet.
