ROTOR, METHOD OF MANUFACTURING ROTOR, AND MOTOR |
摘要 |
The method includes the step of: a) defining a base of the rotor cover; b) defining support regions each having a cross section in a shape of a minor arc, and arranged to project radially outward to match the convex surface of a separate one of the magnets; c) arranged the magnets on the outer circumferential surface of the rotor core, and fitting the rotor core with the magnets arranged thereon to the base, and d) deforming a portion of the base which surrounds an opening of the base to define a collar portion projecting radially inward. In step b), each support region is defined such that an inner surface thereof is arranged to have a radius of curvature smaller than that of the convex surface.
