PROBLEM TO BE SOLVED: To provide a motor that assures easy wiring between a coil and commutator piece, even when the slit position of the commutator piece is shifted at changing of the wiring system to the Y-wiring system from the delta-wiring system. SOLUTION: The position of a slit 15 of the commutator piece 9a in a Y- wiring system is shifted by 30 degrees with respect to the center line L1 of teeth 12, namely by 30 degrees from the position of slit 15 of the commutator piece 9a in the delta-wiring system. In this case, a riser 9c extended from the commutator piece 9a is formed, resulting in the bias to the commutator piece body in matching with a center position L4 of a slot 13.
