发明名称 PERMANENT MAGNET TYPE ROTARY ELECTRIC MACHINE
摘要 For providing a permanent magnet type rotary electric machine that can reduce magnetic fluxes concentrated to one side in rotating direction on a magnetic pole circumferential face that causes torque ripple as well as ensure the mechanical strength, in the present invention, an outer circumference of respective magnetic poles is formed in a circular arc having a same curvature as well as the magnetic pole center axes of the respective magnetic poles are displaced with respect to the rotation center of a rotor so that an air gap between a stator and the respective magnetic pole outer circumferences at one side in the rotating direction is widened in comparison with the air gap at the other side.
