The invention relates to an inverter comprising a casing, a circuit board (), a power module, a connector guide () which is configured to keep male connectors of the power module in a given orientation, and a busbar system () connected to the power module () and comprising a ferromagnetic element () that is suitable for interacting with a current sensor () that is rigidly connected to the circuit board (). The inverter () comprises two elongate centering elements such as centering fingers or pins () which extend in parallel and are arranged at a distance from one another, and are rigidly connected to a reference part of the inverter. In this instance, the two elongate centering elements pass through the circuit board (), the connector guide () and the busbar system (), with the casing () or part of the casing () forming the reference part. This ensures that the circuit board (), the connector guide () and the busbar system () are correctly aligned with one another.

Inverter comprising a device for the mutual alignment of three components

The invention relates to a rotating electrical machine () comprising a housing () including two bearings (), a rotor shaft () mounted to rotate freely in the housing via the bearings, a rotor () clamped to the rotor shaft so as to rotate the rotor shaft and comprising first () and second () axial end faces, and a cooling circuit comprising a coolant supply duct () arranged coaxially in the rotor shaft, and a radially oriented feed duct () arranged in the rotor shaft and in fluid communication with the supply duct and the rotor, characterized in that the cooling circuit further comprises a cooling chamber () in fluid communication with the feed duct, extending axially between the rotor and the rotor shaft, opening onto the first and second axial end faces and delimited radially by an angular portion of an external surface () of the rotor shaft and an angular portion () of an internal surface of the rotor, the two portions extending opposite and at a distance from one another.

Rotating electrical machine having a circuit for cooling magnets by the shaft

The rotating electric machine () having a housing comprising first () and second () clamp members and an inner face, a stator comprising a stator body () clamped between the first and second clamp members and having an outer face extending opposite the inner face together defining an annular cooling chamber () surrounding the stator body, the stator body comprising a longitudinal stack of stator sheets (), each stator pack of which comprises an annular core having an outer circumference and at least two radially centrifugal protuberances projecting from the outer circumference of the annular core, in the annular cooling chamber, and diametrically opposite one another, the stator sheets of the longitudinal stack being identical and two adjacent stator sheet of the longitudinal stack being angularly offset from each other such that the respective protuberances thereof do not extend opposite one another.
