THREE-DIMENSIONAL AXIAL GAP TYPE ROTATING ELECTRIC MACHINE

摘要

An axial gap type rotating electric machine including a stator that includes m salient poles that protrude from a discoid magnetic material in a rotating shaft direction and are arranged in a circumferential direction. A winding wire is wound around an outer periphery of each of the salient poles. The rotor includes n permanent magnet poles and n rotor magnetic materials that are alternately arranged in the circumferential direction. The permanent magnet poles each include a magnet pole piece and a permanent magnet that are fixedly attached to each other and arranged in an axial direction, the magnet pole piece being made of a magnetic material. A plurality of teeth are formed in a concentric arc-like manner in an opposing part between: the magnet pole pieces and the rotor magnetic materials; and the stator so as to engage with each other with the intermediation of the air gap.

1. An axial gap type rotating electric machine comprising:
a stator and a rotor that are opposed to each other with an intermediation of an air gap; and a winding wire axis and a rotating shaft parallel to each other, wherein the stator includes m salient-pole parts that protrude from a discoid magnetic material in a rotating shaft direction and are arranged in a circumferential direction, a winding wire is wound around an outer periphery of each of the salient-pole parts, the rotor includes n permanent magnet poles and n rotor magnetic materials that are alternately arranged in the circumferential direction, the permanent magnet poles each include a magnet pole piece and a permanent magnet that are fixedly attached to each other and arranged in an axial direction, the magnet pole piece being made of a magnetic material, polarities of the permanent magnet poles are alternately arranged in the circumferential direction such that the permanent magnet poles are magnetized into opposite polarities in the axial direction, a plurality of teeth are formed in a concentric arc-like manner in an opposing part between: the magnet pole pieces and the rotor magnetic materials; and the stator so as to engage with each other with the intermediation of the air gap, m is a positive integer, and n is a positive even number.
