Patent ID: 7345387

Claim:
A dynamoelectric machine comprising: a case having a suction aperture for sucking in air and a discharge aperture for discharging said air; a rotor including: a rotor coil disposed so as to be fixed to a shaft inside said case, said rotor coil generating magnetic flux on passage of electric current; and a Lundell pole core disposed so as to cover said rotor coil, said pole core having a plurality of claw-shaped magnetic poles that are magnetized by said magnetic flux; a stator including: a stator core disposed so as to surround said rotor; and a stator coil formed by winding a conducting wire into slots extending axially on said stator core; a fan rotating together with said rotor, said fan directing said air from said suction aperture into said case, blowing said air centrifugally, and discharging said air externally through said discharge aperture, said pole core being constituted by a first pole core body and a second pole core body in which said claw-shaped magnetic poles intermesh with each other alternately, wherein: said fan has a blade including an interposed portion extending axially from an end surface of said pole core between an adjacent pair of said claw-shaped magnetic poles wherein the interposed portion is bent at a bent portion so as to have an angular shape.
