Abstract: Leakage of a magnetic flux from inside diameter face of claw magnetic poles is reduced to improve output, and deformation and vibration of the claw magnetic poles are reduced. A rotor includes: a rotor coil for generating magnetic flux; a pole core comprised of a first pole core body and a second pole core body that are arranged so as to cover the rotor coil, each being provided with protruding claw magnetic poles 21, 22 engaging with each other; a magnet 31 for reducing leakage of magnetic flux leaking from inside diameter side of the claw magnetic poles 21, 22; and a magnet-holding member 32 for supporting the magnet 31 on the claw magnetic poles 21, 22.

Abstract: A rotor of a dynamo-electric machine according to the present invention including a pole core provided so as to cover a rotor coil generating a magnetic flux and being made up of a first pole core body and a second pole core body having respectively tooth-shaped magnetic poles projecting so as to mesh alternately with each other, includes magnet ASSYs as the magnetic element having magnets disposed on the both side surfaces of the tooth-shaped magnetic poles for reducing magnetic flux leakage from between the side surfaces of the adjacent tooth-shaped magnetic poles, and magnet retaining members for supporting the magnets on the tooth-shaped magnetic poles, and resin members filled between the magnet ASSYs at the position between the opposing surfaces thereof.

Abstract: In an electric rotating machine, a rotor can be manufactured relatively easily at reasonable cost without high working accuracy for pole cores, and a permanent magnet can be assembled without impairing cooling efficiency of the rotor. A magnet-holding member 7 is separately fixed to a claw-shaped magnetic pole 21 of at least one of a pair of pole cores 2, 3; each magnet-holding member 7 is provided with a magnet mounting part 72 on which a permanent magnet 5 is mounted on two sides of the claw-shaped magnetic pole 21 in circumferential direction; and each magnet mounting part 72 is formed so as to be located between the claw-shaped magnetic poles 21, 31 engaged with each other.
