Axial gap-type power generator
View Patent ↗An axial gap-type power generator has: a rotor fixed to a crankshaft of an engine; a stator fixed to a crankcase of the engine and opposing the rotor across a spacing in an axial direction; and a housing to house the rotor and the stator and to fix the stator. The stator is configured by arraying, in a peripheral direction, a plurality of coils C each configured through winding of a winding about a stator core. The housing is formed of a resin-based material. Winding ends of the coils are wired using connector fittings each of which is formed of a metal plate, is held on the housing, and has a clamp into which the winding end is inserted and clamped.
