Claims
- 1. A brush-less rotary electric machine comprising:
a frame having a first and second walls and a pair of bearings respectively fixed to said first and second walls; a stator core having a plurality of slots, said stator core being fixed to said frame; an armature coil formed of a plurality conductor segments disposed in said plurality of slots, said conductor segments having a first coil end at an axial end of said stator core and connection ends connected to one another to form a second coil end at the other end of said stator core; a rotor shaft rotatably supported by said frame via a pair of bearings fixed to said frame: a generally cylindrical stationary yoke; a rotary yoke disposed opposite the inner periphery of said stationary yoke and fixed to said rotor shaft; a plurality of first claw pole members extending from an end of said rotary yoke to be disposed opposite the inner periphery of said stator core; a plurality of second claw pole members each of which is disposed between said first claw pole members opposite the outer periphery of said stationary yoke, said second claw poles being fixed to said first claw pole members by a support member; and a field coil fixed to said stationary yoke and wound around said rotary yoke, wherein said armature coil has a plurality of radial air passages at said second coil end, and each of said plurality of second claw pole members has a projection portion disposed close to said second wall.
- 2. The brush-less rotary electric machine as claimed in claim 1, wherein
said connection ends are disposed opposite said plurality of second claw pole members.
- 3. The brush-less rotary electric machine as claimed in claim 1, wherein
said projection portion is tapered.
- 4. The brush-less rotary electric machine as claimed in claim 1, wherein
said plurality of second claw pole members is supported by an annular magnetic member spaced apart from said plurality of first claw pole members.
- 5. The brush-less rotary electric machine as claimed in claim 1, wherein said stationary yoke is fixed to said second wall.
- 6. The brush-less rotary electric machine as claimed in claim 1, wherein said stationary yoke is disposed to abut said bearing fixed to said second wall.
