Abstract To provide a stator for electric motors that interacts with a rotor magnetically. A first yoke having a plurality of circumferential wall members that are arranged in a circumferential shape to receive a rotor, and a radius wall member that projects radially from the outer-periphery surface of the circumferential wall members; a cylindrical second yoke that is provided separately from the first yoke and is arranged so that it surrounds the first yoke, and has an inner-periphery surface in that the terminal of the radius wall member of the first yoke touches; and a plurality of excitation coils that are wound around the radius wall members of the first yoke; are included. As a result, a coil is easily wound around the first yoke of a stator, thus improving working efficiency, reducing torque change being generated when an electric motor is operated, and hence reducing vibration and noise and improving the performance of the electric motor.
