Abstract (en)
[origin: WO2018130771A1] The present invention provides a stator for a rotating electrical machine, in particular for a motor vehicle, the stator (15) comprising: - a body (27) having notches (37) which open axially into front (38) and rear (39) axial end walls of the body (27) and which are radially open in an inner wall (40) of the body (27), - at least two windings (43), each forming a phase of the stator (15), each winding comprising undulating wire turns which comprise a series of axial strands (44) received in a series of associated notches (37) and connecting strands (45, 46) which connect the successive axial strands (44) and extend alternately beyond the front axial end wall (38) and beyond the rear axial end wall (39). One winding has a shorter wire length than the other winding.
