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).
Claims16
A rotary electrical machine for a motor vehicle, comprising:
- a rotor with an even number of pairs of poles;
- a stator comprising a body provided with notches;
- and
- a three-phase winding inserted in the notches of the stator body,
- the three-phase winding comprising:
- at least one first group of portions of phases and one second group of portions of phases associated with a first assembly of at least three bridge arms, and
- at least one third group of portions of phases and one fourth group of portions of phases associated with a second assembly of at least three bridge arms,
- wherein, around a circumference of the stator, there is alternation between a group of portions of phases of the first assembly of bridge arms and a group of portions of phases of the second assembly of bridge arms.
