FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, in particular to cellular closed ventilation cooling devices for electrical machines. It is achieved by the fact that axial ventilation holes are uniformly distributed in circumferential direction, at that, the above holes are located at the distance from the motor stator winding. A round tube of stainless steel passes through the axial vent hole, two ends of the axial ventilation tube and the disk are permanently connected, and the ventilation opening opens above the disk on the housing.
EFFECT: technical result consists in providing effective improvement of cooling effect of stator yoke core and in providing safe and stable operation of engine.
