PROBLEM TO BE SOLVED: To provide a small and highly efficient motor by optimizing a yoke, teeth, and a core height in the axial direction of a portion where the teeth face the rotor, in a stator core of a motor. SOLUTION: In the stator core, heights in the axial direction of the teeth 2a is configured to be lower than the height of the yoke 1a and the portion 3a where the teeth face the rotor. By reducing heights of coils wound on the teeth and of an insulator, miniaturization and high efficiency can be achieved. COPYRIGHT: (C)2005,JPO&NCIPI
