The invention relates to a busbar () arranged so as to electrically connect at least one power electronic module () from at least one electrical conductor () to which the busbar () can be connected. The busbar () comprises a plurality of coaxial sleeves (). Each of the sleeves () comprises a plurality of arms () that are distributed peripherally and radially around an axis (A) of the sleeves (). The arms () extend longitudinally in parallel to the axis (A) and each include at least one conductive track () forming one of the buses of the busbar (). The invention also relates to a power electronic module incorporating a busbar in accordance with the invention, and to a vehicle fitted with said module.

Busbar including a plurality of coaxial sleeves provided with arms endowed with electrical tracks

The invention relates to a sleeve () providing a mechanical connection between a shaft of an electrical machine and a rotational bearing of the electrical machine () comprising: &#x2014;a first portion () arranged to co-operate with the electrical machine shaft, &#x2014;a second portion () arranged to co-operate with the rotational bearing, characterized in that the first portion () defines at least one internal chamber () and comprises at least one means of communication () between an environment surrounding the sleeve () and the internal chamber (). Said invention is applicable to motor vehicles.

Sleeve and shaft for an electrical machine

The invention relates to an assembly () comprising an electrical machine () comprising: a stator () having windings forming coils (), a rotor (), a shaft () rotating the rotor (), and an impeller () for cooling the electrical machine, said cooling impeller () comprising at least two crowns (), including a first crown () and a second crown (), each crown () comprising blades (), the blades () of the first crown () of the cooling impeller () being arranged so as to generate the circulation of a cooling fluid flow in a first direction (F), and the blades () of the second crown () being arranged so as to generate the circulation of the cooling fluid flow in a second direction (F), the second direction (F) opposing the first direction (F). Said invention is applicable to motor vehicles.
