Abstract
The invention relates to a closed rotary electrical machine incorporating a cooling system comprising two internal fans secured on the shaft of the rotor, at the two ends of the rotor. Each fan faces the inner face of a flange comprising fins orient the flow of air created by the internal fans and can capture the heat from operation of the machine. A casing which contains the rotor and the stator of the electrical machine is sealed by two flanges. The cooling system also comprises external cooling for cooling the casing and flanges, comprising air or liquid.
