ELECTRIC MOTOR WITH COMBINED LIQUID AND AIR COOLING

摘要

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 vapour, 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.
