Abstract
Coils are provided on a plurality of tooth sections of a core. The coils are formed by successively winding a conductor on the tooth sections with at least one tooth section between each successive windings, such that each portion of the conductor extending between two tooth sections located with at least one tooth section therebetween forms a jumper wire extending in the circumferential direction of the core. A commutator has a plurality of claw portions projecting to the outside of the commutator. Each of the claw portions electrically connects one of a plurality of segments to one of the jumper wires. When the core and the commutator are attached to a rotary shaft, each claw portion is arranged at a position corresponding to one of the jumper wires as viewed in the axial direction of the rotary shaft.
