ELECTRIC MOTOR WITH GAS-LIQUID AEROSOL COOLING Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: device has stator 1, rotor 2, gas coolers which are located in housing 3 with end walls 4, bandage rings 5, fans 6 which are mounted on rotor shaft, supply cases which are designed as whirl chambers 7 and serve as mixing heat exchange units because end of cylinder 9 has ring shoulder on side of end wall and enters into cone 10 so that ring space 11 is provided between it and surface of cone 10. Cylinders 12 are mounted in coaxial with shaft between cones 10 and fans 6. Drain pipes 13 are provided in bottom of cylinders 12. Nozzles 14 at end walls 4 are mounted at acute angle to cylinders 12 and in circle around axis of rotor shaft so that liquid flows which are ejected from them shape flux which is turned around shaft axis. Part of nozzles with supply pipes are located in space between stator and rotor where cold liquid is spread and cools gas-liquid mix and heated members. Lower part of housing 3 contains drain pipe 18. EFFECT: increased reliability, increased efficiency, decreased usage metal. 4 dwg
