PURPOSE: A stator for a motor is provided to easily wind a coil on a salient pole of a stator, and reduce a variation in magnetic flux density generated during an operation of a motor. CONSTITUTION: The first yoke part is shaped like a loop and accommodates a rotor. The first yoke member is integrally formed on the first yoke part and has a plurality of salient poles in a radial direction thereon. The second yoke member(50) is arranged coaxially with the first yoke member and takes a ring shape which has an inside surface being contacted with free end parts of the salient poles. An engaging groove is formed along a shaft line on the inside of the second yoke member(50). A protrusion is protruded on the salient pole and engaged with the engaging groove(51). A depressed groove(53) is formed on an outside surface of the first yoke part and depressed along a shaft line between adjacent salient poles at equiangular intervals.
