FIELD: electromechanical engineering. SUBSTANCE: electrical machine has wound stator with core provided with radial cooling ducts. Stator frame accommodates gas coolers and is closed with end shields. End windings 10 of rotor are held in position by means of binding rings. Rotor barrel is covered with shell and has longitudinal partitions 13. Barrel has large teeth 19 and slot wedges 20 built integral with partitions 13 that have extended portions. Slots made at joints of extended portions accommodate shims 25. Wedges are provided with holes 27 communicating with axial ducts 28; holes 30 are made in partitions 13 between ports 23. EFFECT: improved cooling efficiency of rotor winding at high efficiency; reduced manufacturing cost of machine. 4 cl, 6 dwg |
