ができることを確認した。As described above, according to this embodiment, the number of commutator pieces is an integral multiple of the number of slots in the rotating iron core, and the coils wound around the pair of slots in the rotating iron core and the commutator pieces including the coils wound in the pair of slots in the rotating iron core are arranged. Since the armature coil is made up of an IR winding made up of a coil wound around a pair of slots, rectification is improved, the black bar phenomenon is suppressed, and the life of the brush can be improved. . As a result, the life of the rib will also be improved. As a result of examining a 500W class AC commutator motor, it was confirmed that the brush life could be extended by 1.3 times.
