FIELD: electromechanical engineering. SUBSTANCE: cooling system has cooling loops in the form of single-pass helical ducts disposed in electrical machine stator frame and connected with aid of flexible high-pressure hoses to hermetically sealed end-shield cavities. Air bypass ducts communicating through ports with inner space of stator frame are rigidly fixed over frame perimeter. Stator frame, bearing unit, and cooling air circulating over closed circuit inside electrical machine are effectively cooled down. EFFECT: enhanced efficiency of cooling system. 2 dwg |
