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 () comprising a body () and poles () that are formed by permanent magnets (), characterized in that —two successive polar angles, each corresponding to a circumferential extent of a pole (), or —two successive dual polar angles (A-A), each corresponding to a circumferential extent of two adjacent poles (), —exhibit an angular difference in relation to one another that is dependent on an angular offset parameter () related to a stator pitch.

Rotary electrical machine with a rotor configuration which reduces the torque ripples

The invention predominantly relates to a rotating electrical machine for a motor vehicle, comprising: a rotor having an even number of pole pairs Np; and a stator () comprising a body provided with slots and a three-phase winding () inserted into the slots in the stator body. The three-phase winding () comprises: at least a first group (G) of portions of phases (U, V, W) and a second group (G) of portions of phases (U, V, W) which are associated with a first set of at least three bridge arms (); and at least a third group (G) of portions of phases (U, V, W) and a fourth group (G) of portions of phases (U, V, W) which are associated with a second set of at least three bridge arms ().
