Each of the teeth includes a first branch portion and a second branch portion. Each of segments in the commutator has a riser. A start end and a terminal end of the concentrated winding wire are pulled out separately in a direction getting closer to the commutator and in a direction away from the commutator. The conductor between the concentrated winding wires is hooked by the riser by which the conductor between the other concentrated winding wires is not hooked. A start end and a terminal end of the distributed winding wire are pulled out separately in a direction getting closer to the commutator and in a direction away from the commutator. The conductor between the distributed winding wires is hooked by the riser by which at least one of the conductor between the concentrated winding wires and the conductor between the other distributed winding wires is not hooked.

摘要： A double-stator motor of an example embodiment includes: an annular rotor connected to a rotary shaft and integrally rotates with the rotary shaft, an inner stator arranged radially inward of the rotor, and an outer stator arranged radially outward of the rotor. The rotor includes a plurality of segments annularly arranged in the circumferential direction, spaced apart from each other by a predetermined distance, and a plurality of permanent magnets each interposed between circumferentially adjacent segments, the permanent magnets being alternately magnetized in the circumferentially opposite direction. The rotor, the inner stator and the outer stator have the same number of poles. The inner and outer stator windings of the inner and outer stators, respectively, are connected so that their phases are reversed to each other. Thus, the magnetic fields generated by the magnetomotive forces of the inner and outer stators are applied to specific segments in parallel.
