PROBLEM TO BE SOLVED: To provide a motor having high output density by selecting the relation between the total number of magnetic poles of a rotor of a rotary electric machine in which a stator magnetic pole is divided in a circumferential direction and the total number of magnetic poles of a stator thereof in order to solve the problem that a coupled core external circumferential portion of a stator magnetic pole causes magnetic interference in each of phases and a control constant of a controller to be driven is influenced by another phase, resulting in less controllability in a conventional technique. SOLUTION: The rotary electric machine has a stator in which a three-phase stator magnetic pole and a stator winding are provided, the three-phase stator magnetic pole is disposed in a circumferential direction, the stator winding is wound around the stator magnetic pole composed of two columns centered at the circumferential direction for each phase, and the three-phase stator magnetic pole is magnetically divided. In this rotary electric machine, the number of stator magnetic poles is a multiple of 6. COPYRIGHT: (C)2009,JPO&INPIT
