Abstract:
An axial gap type rotating electric machine, having a stator with first tooth parts protruding in an axial direction and formed in a concentric arc-like manner, and a rotor with magnetic poles arranged in a distributed manner in the circumferential direction, and the magnetic poles include second tooth parts that protrude in the axial direction and are formed in a concentric arc-like manner, the second tooth parts being opposedly arranged so as to respectively engage with the first tooth parts with the intermediation of the air gap. The rotor is incorporated in the rotating member so as to be movable in the axial direction and so as not to be rotatable with respect to the rotating member. The rotating electric machine further includes an urging device that makes the air gap between the rotor and the stator adjustable.
