    The operation of the device is 35 as follows.
    The blades of the axial fan 2 create and accelerate the main air stream. 11, blown through the radiator 1. Centrifugal blades 7 absorb 40 stream 1.4 of air cooling the electric motor 3.
    The air stream 14 enters through the intake holes 12, blows around the inside of the electric motor 3 and enters the space enclosed 4 between the engine 3 and the end wall of the hollow rotor 5. The cooling air stream is pumped into the zone 15 through. the holes 16 and then is picked up by the blades of the axial fan 2. The air entering through the holes 12 and the cooling motor 3 is drawn from the main air stream 11, sucked by the blades of the axial fan 2 and moves in the direction of the stream 17 before entering the concave parts of the legs 9. However, to get into the concave part 10 of the legs 9 stream 17 should change direction by 180 °. With this change in direction, the air is freed from droplets · of water 18, which it carries with it and which tend to continue its movement in the previous direction of flow 11. Thus, the ingress of water along with the air flow to the working parts of the electric motor 3 is excluded.
    The implementation of the foot in the U-shape also contributes to the same effect.
