FIELD: electromechanical engineering; stator winding ventilation systems. SUBSTANCE: ventilation system includes stator core with winding placed in slots closed by slot wedges, radial ducts of adjacent teeth formed by spacers, tangential through ducts disposed under slot wedges and used to provide intercommunication between ducts of adjacent teeth thereby forming radial-tangential duct with cooling air inlet and outlet on stator back end. EFFECT: augmented cooling of slot and tooth area of stator. 1 cl, 2 dwg |
