PROBLEM TO BE SOLVED: To reduce the structural size of a motor provided with two exciting coils on a stator which generate a composited magnetic field, and facilitate the manufacturing. SOLUTION: This motor is provided with two independent exciting coils 22, 23 on a stator 19 which generate a composited magnetic field. The stator 19 has multi-arm type structure. Arms 20a, 20b; 21a, 21b which are positioned facing each other are bent in such a manner that the respective exciting coils 22, 23 between the respective arms generate magnetic force vectors which perpendicularly intersect each other.
