ABSTRACT:
A stator core is formed into a cylindrical shape, 3n teeth are disposed at a predetermined pitch in a circumferential direction where n is a positive integer, and slots are formed between adjacent pairs of the teeth so as to open onto an inner circumferential side. A stator coil is installed as a concentrated winding in the stator core. A rotor is rotatably disposed inside the stator and 2n permanent magnets are disposed at a predetermined pitch in a circumferential direction on an outer peripheral portion of a shaft. The stator core is constructed such that a slot opening (d) and a slot pitch (p) at an inner circumferential surface of the stator core satisfy an expression 0.1≦d/p≦0.3.
