摘要： A miniature motor includes: a plurality of magnets serving as stator poles and attached to an inner surface of a motor casing having a closed-bottomed cylindrical shape; a salient-pole rotor having a core mounted on a rotor shaft and windings placed on the core; and a commutator mounted on the rotor shaft. The core includes a center portion having a hole formed therein at the center for engagement with the rotor shaft, a plurality of leg portions extending integrally and radially from the center portion in equal number with the salient poles, and a plurality of wing portions, each extending integrally and symmetrically from an end of each of the leg portions. The core includes core laminations blanked from sheet steel and assembled together and is formed through deformation of the entire wing portions such that the radius of a circumcircle of the core coincides with a designed final radius of curvature of outer circumferential surfaces of the salient poles of the rotor.
