摘要 |
An axial gap type electric rotating machine includes a rotor arranged to rotate about an axis of rotation, and a stator arranged so as to face the rotor with a predetermined gap in an axial direction of the axis of rotation. The rotor includes a back yoke and an annular rare earth bonded magnet made of a circumferentially continuous member fixed to the back yoke. The magnet is magnetized so that an N-pole and an S-pole of magnetic poles are arranged alternately in a circumferential direction, and includes cutout portions formed between adjacent magnetic poles. The stator includes a plurality of tooth portions arranged along a circumferential direction so as to face the magnet and a winding wound on the tooth portions. Each tooth portion has a pair of side protruded portions each formed at a tip end portion facing the magnet so as to extend in the circumferential direction. |
