  • Patent number: 9912204
    Abstract: In conventional rotors having a shape in which permanent magnets are skewed, a configuration in which, for example, the thicknesses of both ends of each magnet are increased is used in order to make the rotors symmetric between the forward and reverse directions, thereby causing excessive increase in the thicknesses. In a rotor 2 in which permanent magnets form magnet poles and the permanent magnets are skewed with respect to the axial direction, the thickness of each permanent magnet is increased at a portion that is most likely to be demagnetized, that is, a positive side portion F in a rotor part 2A skewed in the positive direction and a negative side portion F in a rotor part 2B skewed in the negative direction, whereby a demagnetization resistance strengthened portion is formed.
