FIELD: electricity.
SUBSTANCE: electrical machine cooling device comprises a stator with axial cooling channels, Peltier's module, the junctures of which are electrically isolated from the electrical machine structure. Cold junctures of Peltier's module are interfaced to the external surface of the stator package, and hot ones are interfaced to the internal surface of the electrical machine housing. Peltier's module is heat isolated by its 1/5 of the section from hot junctures. Peltier's module is connected by electric terminals to DC power supply - the thermocouple battery, the hot juncture of which is located in the combustion chamber of the aviation engine, and the cold juncture - on the housing of the input part of the aviation engine interfaced to the air inlet.
EFFECT: use of thermal energy of aviation engine for power supply of active cooling system.
