摘要： A commutator main body has a cylindrical insulating body, and a plurality of segments arranged in an outer circumference of the insulating body. A short-circuit member is arranged in an end in an axial direction of the insulating body. The short-circuit member has a plurality of first short-circuit pieces and a plurality of second short-circuit pieces. A tabular insulating portion covers first coupling portions of the first short-circuit pieces, and second coupling portions of the second short-circuit pieces. The insulating portion has a restriction recess, and the end in the axial direction has a restriction projection. The restriction projection is engaged with the restriction recess, whereby the movement of the short-circuit member in the circumferential direction with respect to the commutator main body is restricted. Accordingly, the assembly of the short-circuit member in the commutator main body is facilitated.

摘要： Ferromagnetic bodies, the number of which is n (n is an integer greater than or equal to two), are secured to an inner circumferential surface of a cylindrical yoke. A first gap S1 is provided between ferromagnetic bodies that are adjacent to each other in the circumferential direction. Active magnetic poles, the number of which is m (m is an integer greater than or equal to two), apply magnetic fields to each ferromagnetic body from radially inside. As a result, each magnet has magnetic pole portions the number of which is m. A third gap is provided between each pair of the active magnetic poles that correspond to a common ferromagnetic body. The angular width of the third gap is set greater than a first angular width of the first gap. As a result, all magnetic pole centers are easily arranged at equal angular intervals.

摘要： 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.

The magnetic poles are arranged at a predetermined pitch along a circumferential direction of the yoke. The number of the magnetic poles is represented by the expression: 2×P (P is an integer not less than 2). The commutator has segments that are arranged in a circumferential direction of the commutator. The number of the segments is represented by the expression: P×N (N is an odd number not less than 3). The armature core is rotatable integrally with the commutator and includes teeth provided by the number represented by the expression: 2×P×N. A coil is wound around the teeth by distributed winding. Each one of the brushes is pressed against and contacts the segments. Two of the segments that are electrically short-circuited by one of the brushes are connected to each other by at least two coils that are arranged at an interval corresponding to an integral multiple of the pitch (360°/(2×P)) of the magnetic poles.
