PROBLEM TO BE SOLVED: To provide a stator core which enhances torque characteristics of a motor by restraining a rotating field generated by teeth of a stator effectively, thereby reducing iron loss, and to provide a motor having the stator core. SOLUTION: The stator core 10 comprises an annular yoke 2 and a plurality of teeth 1, ... protruding radially inward from the yoke 2 and formed to have a predetermined height. In the teeth 1, slits 3, ... are formed to extend radially from the boundary between the yoke 2 and the teeth 1, i.e., the root of the teeth. COPYRIGHT: (C)2009,JPO&INPIT
