ELECTRICAL MACHINE STATOR Russian patent published in 1995 - IPC

FIELD: electromechanical engineering. SUBSTANCE: stator core 1 is fitted in frame 2 and has middle stacks 3 and extreme stacks 4 axially compressed by pressure members 5 with hold-down pins 6 and hold-down plates 7. Core slots accommodate winding 8 held in position by metal wedges 9 threaded at cylindrical ends 10. Wedge ends carry straps 11, washers 12, and nuts 13. Flexible member may be fitted under washer 12. Bracing studs 18 mount springs 19 supported by external surface of plate 7. Elastic members 17 fitted on studs 15 are installed on its periphery. EFFECT: improved reliability due to steady pressure of core compression during its expansion and contraction. 4 cl, 5 dwg
