PROBLEM TO BE SOLVED: To prevent the inductance mismatch of each phase while simplifying the constitution of a stator. SOLUTION: Stator rings 11, 12 and 13 are arranged concentrically with an axial line P and connected so as to be overlapped with one another along the axial line, claw-shaped induction poles 22, 24 and 26 are set so as to sequentially be disposed along the circumferential direction, and anα-phase ring-shaped winding 14 is fixed so as to be sandwiched from both sides in the axial direction by base ends of the claw-shaped induction poles 22, 24 axially arranged at a prescribed interval, when the axial end face of an A-phase back yoke 21 and the other axial end face of a B-phase back yoke 23 abut on each other. Aβ-phase ring-shaped winding 15 is fixed so as to be sandwiched from both the sides in the axial direction by base ends of the claw-shaped induction poles 24, 26 axially arranged at a prescribed interval, when the other axial end face of the B-phase back yoke 23 and the end face of a D-phase back yoke 25 abut on each other.
