Abstract (en)
[origin: WO2018193012A1] The invention relates mainly to a rotating electrical machine (10) for a motor vehicle, comprising: - a rotor; - a stator (11) extending along an axis, said stator (11) comprising a body (24) provided with a plurality of stator teeth (28) defining slots (30, 30'), - the stator (11) comprising a winding with conductors (35) housed in the slots (30, 30'); - in a plane (P) orthogonal to the axis along which the stator (11) extends, - a first slot (30) has a first width (L1) measured in an orthoradial direction, radially in the middle of the first slot (30), and - a second slot (30'), separate from the first slot (30), has a second width (L2) measured along an orthoradial direction, radially in the middle of the second slot (30'); characterised in that the first slot width (L1) is different from the second slot width (L2).
