Abstract: A rotating electric machine comprising at least one end flange carrying a bearing, and a housing onto which the end flange is attached, said housing being cooled by a liquid cooling circuit and having at least two connectors communicating with the cooling circuit. The two connectors allow the supply and return of cooling liquid to and from the flange when the flange is configured to be cooled by a flow of the cooling liquid.

Abstract: Electric motor includes a housing provided with an opening equipped with a membrane forming a barrier to liquid water between the inside and the outside of the housing but permeable to water vapor, the stator being liquid cooled and the motor having an internal fan to generate a forced circulation of air inside the motor, the membrane being situated in a region in which the forced circulation of air exposes it on the inside to a pressure higher than atmospheric pressure.

Abstract: This motor (10) comprises a main casing (12), a brush holder (18) positioned in the main casing (12) and an electrical power supply device (20) secured to the holder (18), comprising an electronic control board. The board has at least one connector (78, 44) for electrical connection to the brush holder (18). The motor (10) comprises an auxiliary casing (22) positioned on the outside of the main casing (12). The auxiliary casing (22) defines a liquid-tight interior volume housing the electronic board. The auxiliary casing (22) is mechanically connected to the brush holder (18) by the electrical connection connector (78, 44) through a passage opening (38) formed in the main casing (12).
