ROTARY ELECTRIC MACHINE HAVING A ROTOR CONFIGURATION THAT DECREASES TORQUE RIPPLE

摘要

The invention pertains primarily to a rotary electric machine, in particular for a motor vehicle, including: - a stator comprising a body provided with teeth delimiting slots and a winding that is housed in the slots of the stator body; - a rotor (12) comprising a body (21) and poles (22) that are formed by permanent magnets (23), characterized in that - two successive polar angles, each corresponding to a circumferential extent of a pole (22), or - two successive dual polar angles (A0-A4), each corresponding to a circumferential extent of two adjacent poles (22), - exhibit an angular difference in relation to one another that is dependent on an angular offset parameter (δ) related to a stator pitch.
