<p>PROBLEM TO BE SOLVED: To provide a stator of SR motor formed by compressing soft magnetic material powder that can be molded by low pressure press while preventing non-uniform density distribution from occurring internally, and to provide an SR motor including this stator.SOLUTION: The stators 30, 30A of SR motors 10, 10A include stator bodies 32, 32A surrounding a rotor 20 in the direction of rotation, and a plurality of magnetic poles 341, 341A extending radially inward from the stator bodies 32, 32A toward the rotor 20, and arranged in the direction of rotation. At least the magnetic poles 341, 341A are formed by solidifying soft magnetic powder coated with an electric insulation film. The stators 30, 30A are constituted of more than one part separable between the magnetic poles 341, 341A adjacent in the direction of rotation, and a predetermined part out of the more than one part has a shape to be fitted in the remaining parts.</p> |
