Abstract
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 (10) comprising a body provided with slots and a three-phase winding (14) inserted into the slots in the stator body. The three-phase winding (14) comprises: at least a first group (G1) of portions of phases (U, V, W) and a second group (G2) of portions of phases (U, V, W) which are associated with a first set of at least three bridge arms (21.1); and at least a third group (G3) of portions of phases (U, V, W) and a fourth group (G4) of portions of phases (U, V, W) which are associated with a second set of at least three bridge arms (21.1).
