Abstract

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.

First claim

The invention claimed is:

1. An axial gap-type power generator, comprising:
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,
wherein the stator is configured by arraying, in a peripheral direction, a plurality of coils 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 the connector fittings is formed of a metal plate, and is held on the housing, wherein the winding end is inserted and clamped into a clamp of the connector fitting;
the stator has a first stator and a second stator that are disposed flanking the rotor in a rotation axial direction;
the housing is configured by combining a first member for holding the first stator and a second member for holding the second stator; and
an electric circuit provided on the side of the first member and an electric circuit provided on the side of the second member are wired to each other by way of a connector that is formed integrally with a joint of the first member and the second member.

2. The axial gap-type power generator according to claim 1 , wherein the coils are connected to each other through insertion of a winding end of one coil into one clamp of each connector fitting that has clamps at both ends, and through insertion of a winding end of another coil to another clamp.

3. The axial gap-type power generator according to claim 1 , wherein the connector fittings are fitted in recesses that are respectively formed in an inner face side and an outer face side of the housing.

4. An axial gap-type power generator, comprising:
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,
wherein the stator is configured by arraying, in a peripheral direction, a plurality of coils 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 the connector fittings is formed of a metal plate, and is held on the housing, wherein the winding end is inserted and clamped into a clamp of the connector fitting; and
the connector fittings are fitted in recesses that are respectively formed in an inner face side and an outer face side of the housing.

5. The axial gap-type power generator according to claim 3 , wherein the coils are connected to each other through insertion of a winding end of one coil into one clamp of each connector fitting that has clamps at both ends, and through insertion of a winding end of another coil to another clamp.

6. The axial gap-type power generator according to claim 4 , wherein the coils are connected to each other through insertion of a winding end of one coil into one clamp of each connector fitting that has clamps at both ends, and through insertion of a winding end of another coil to another clamp.
