US 2010/0141075 A1 · AXIAL GAP MOTOR

Abstract

An axial gap motor, including: a rotor having permanent magnet pieces; and a pair of stators that are oppositely arranged so as to sandwich the rotor in a rotation axis direction thereof, wherein: the rotor includes magnetic material pieces that are arranged along a circumferential direction thereof in a manner alternating with the permanent magnet pieces; the permanent magnet pieces have a magnetization direction in parallel with the rotation axis direction, with N poles thereof opposed to the stator on one side in the rotation axis direction, and with S poles thereof opposed to the stator on the other side in the rotation axis direction; and each of the magnetic material pieces includes magnetic material piece penetration portions that penetrate in a direction parallel to the rotation axis direction.
