  • Patent number: 12477679
    Abstract: An electronic unit for a voltage converter of a rotating electric machine includes a first busbar including a first plate, a first connection portion projecting from the first plate, on a first side of the first plate. A first connection surface is able to be welded to a second connection surface of a third busbar of a power electronics module by a first laser weld using a first laser beam. A second busbar separate includes a second plate parallel to and located on a second side of the first plate, opposite the first side. The first or second busbar includes a first extension extending in line with the first connection surface, the first extension being able to block the first laser beam. A voltage converter can include the electronic unit, and the electrical assembly can include the voltage converter and a rotating electric machine.

  • Publication number: 20250212369
    Abstract: A thermal coupling device for a common mode inductor, configured to transfer heat to a heat sink. The device includes an annular prismatic ferrite core configured to be passed through by at least one electrical connector of an electronic component. A stand is secured to the heat sink, the ferrite core being in contact with the stand and the stand being configured to transfer the heat generated by the ferrite core to the heat sink. The thermal coupling device includes a clamping member configured to hold the ferrite core and the stand secured together, the ferrite core, the stand and the clamping member extending orthogonally with respect to the longitudinal reference plane of the electrical connector.

  • Patent number: 12212205
    Abstract: A stator for a rotary electric machine includes a stator body having an axis (X), and a winding including at least one overhang projecting axially from the stator body and winding ends extending axially beyond the overhang from the stator body. Also included is an interconnector mounted on the overhang of the winding, including an insulating body and at least one track having track ends. At least two winding ends are each assembled with one of the corresponding track ends, and the track ends are symmetrical relative to a plane containing the axis and relative to a plane transverse to the axis.

  • Patent number: 12212202
    Abstract: The invention relates to a rotary electric machine, in particular for a motor vehicle, including: a stator (100) comprising a stator body (110) and an electrical coil, said electrical coil including a plurality of phase windings (120) forming a bundle (125) that protrudes from an axial end face of the stator body, each phase winding including an end forming a coil connection point (122); and at least one electrical connection member (150) positioned in continuation of the stator (100) and comprising at least one electrically conductive element (155) which is overmolded with an electrically insulating material (126) and extends radially out of the electrically insulating material to form at least two connection outputs (153, 154) to which the connection points are connected.
