Patent ID: 7368841

Claim:
A dynamoelectric rotor comprising: a rotor coil for generating a magnetic flux; first and second pole core bodies disposed so as to cover said rotor coil, each comprising a plurality of claw-shaped magnetic poles projecting so as to alternately intermesh with each other; a plurality of magnets disposed near two side surfaces of said claw-shaped magnetic poles to reduce leakage of magnetic flux between said side surfaces of adjacent claw-shaped magnetic poles; a plurality of reinforcing bodies each comprising a base portion and a pair of wing portions formed on two sides of said base portions, said reinforcing bodies each being disposed such that said base portion comes into contact with an inner peripheral surface of said claw-shaped magnetic poles and said pair of wing portions faces said two side surfaces of said claw-shaped magnetic poles, said magnets being supported by said wing portions; a ring-shaped restraining member for supporting said reinforcing bodies by pressing said base portion of each of said reinforcing bodies onto said inner peripheral surface of said claw-shaped magnetic poles from an inner peripheral side; and a retainer for preventing said reinforcing bodies from dislodging toward a tip of said claw-shaped magnetic poles, wherein said retainer is disposed on said base portion of said reinforcing bodies, and wherein said retainer is a step portion comprising a deformed portion of said base portion and having a circumferential segment and an axial segment, and said restraining member being is engaged by said step portion, whereby said restraining member fits between said axial segments and said restraining member fits in contact relation with said circumferential segment and said rotor coil, regulating axial movement and radial movement.
