  • Patent number: 11159070
    Abstract: The invention proposes a stator for a rotating electric machine, in particular for a motor vehicle, the stator (15) including: —a body (27) including notches (37) that are opened radially into an internal wall (40) of said body, —at least one winding (43) forming a phase of the stator, the winding formed from turns (54) includes a first half-phase (49) and a second half-phase (50) that are superposed radially in the notch (37), each turn including a series of axial strands (44) that are received in a series of associated notches and connecting strands (45, 46) that connect the successive axial strands (44) by extending alternatively to protrude with respect to the body (27). A length of wire of each turn of one of the half-phases is larger than the length of wire of each turn of the other half-phase. Furthermore, one of the half-phases has a number of turns higher than that of the other half-phase.

  • Publication number: 20200067363
    Abstract: 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 modulating 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.

  • Patent number: 10447122
    Abstract: Rotating electric machine provided with an axis X. The machine comprises a front part and a rear part. The machine comprises a rotor of axis X comprising two axial end surfaces, each provided with fan blades. The axial surfaces located on the side of the front part and on the side of the rear part. A stator comprises a stator body having slots. The stator comprises a winding installed in the slots and forming a front winding head and a rear winding head. The rotor and the stator are placed in a casing. The front winding head completely masks the blades of the axial surface located on the front side of the machine, along a direction perpendicular to axis X.
