Abstract

The invention provides a rotating electric machine enabling a user to accurately set a clearance between a field magnet of a rotor and a stator with simple work. The rotating electric machine (20) includes the rotor (21) which is mounted to a flywheel (56) so as to be unrotatable around the axis relative to the flywheel (56) rotatable around the axis of a crankshaft (51), and the stator (30) arranged oppositely to the rotor (21) and mounted to a case cover (19) so as to be unrotatable around the axis relative to the case cover (19). Either of the rotor (21) and the stator (30) is mounted to the flywheel (56) or the case cover (19), to which either of the rotor (21) and the stator (30) is mounted so as to be axially unmovable. Either the other of the rotor (21) and the stator (30) is mounted to the flywheel (56) or the case cover (19) so as to be axially movable. The stator (30) is provided with a support for supporting the rotor (21) so as to make the clearance between the stator (30)and the rotor (21) constant.

Description

technical field [0001] The present invention relates to a rotating electric machine, an engine equipped with the rotating electric machine, and a vehicle equipped with the rotating electric machine; engines and vehicles. Background technique [0002] Conventionally, some straddle-type vehicles such as motorcycles have been developed to include a rotary electric machine that can assist engine power or drive the vehicle by its own power (see Patent Document 1, for example). One of such rotating electric machines used for straddle-type vehicles is an axial gap type rotating electric machine, that is, a rotating electric machine in which a rotor and a stator are spaced apart from each other in the axial direction. The axial gap type rotating electric machine includes a disc-shaped rotor joined with magnets generating a magnetic field, and a stator wound with coils that opposes the rotor in the axial direction of the rotary shaft. Generally, the rotor is mounted directly to the...
