  • Patent number: 9385581
    Abstract: The present invention is intended to provide a magnetic gear structure that realizes a magnetic gear that transmits a torque efficiently by reducing eddy currents generated in the interior of magnets. In order to solve the subject described above, in the magnetic gear structure, a structure in which magnets are arranged in the interior of an iron core in an inner rotor portion. Bonded magnets formed by molding, for example, NdFeB powder may be used as the magnets. Since the influence of the eddy current on the side of an outer rotor having a larger pole number is large, a structure in which the magnets are arranged in the interior only of an outer rotor portion having a larger pole number is also applicable. In addition, the magnets to be embedded may be divided into a plurality of pieces. The finer the division of the magnets, the less eddy currents are generated, so that a method of further fining down and assembling the same is also effective.

  • Patent number: 9350206
    Abstract: An axial-gap rotating electrical machine in which the distance of the air gap between a rotor and a stator can be accurately controlled is provided. A large diameter portion and a small diameter portion are formed on a rotating shaft and a stepped portion is formed therebetween. A rotor yoke is secured thereon and the position of the rotor is determined. The position of a bearing secured in a housing for rotatably supporting the rotating shaft is determined by a boss portion of the rotor yoke. The position of the housing is determined by the position of the bearing and the securing position of the stator is determined by a stepped portion formed on the inner circumference of the housing. Thus the position of the housing relative to the rotating shaft can be determined from the position of the rotor and the securing position of the stator can be determined.
