FIELD: electrical engineering. SUBSTANCE: stator has frame 1, laminated core 2 whose slots accommodate bar winding 7 fixing with banding rings 10, 11, 12. Bars 9 and banding rings 10, 11, 12 are fixed with insulating brackets 17 whose bevel surfaces have slots. Brackets 17 are secured on stator frame 1 so that they are supported by hold-down strips 3. slot and steps are provided in bottom supporting member to prevent axial displacement. Each bracket 17 rests through its slot on locking plate having threaded hole to receive bolt. EFFECT: improved reliability due to elimination of short circuit through end windings and banding rings. 3 cl, 8 dwg |
