Disclosed is a double-casing frame of an electric machine that is cooled by a fluid circulating in the fluid circulation space () inside the double casing, said double-casing frame comprising: an inner casing () on which an end flange () is mounted at the rear of the machine; and an outer casing () that fits over the inner casing () and can be separated from the inner casing () without removing the end flange ().

Double-casing frame of an electric machine

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.

Rotating electric machine

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.

Electric motor with combined liquid and air cooling

The present invention provides an electric machine with forced ventilation, the machine comprising:
