STATOR OF HIGH-VOLTAGE ELECTRIC MACHINE Russian patent published in 1995 - IPC

FIELD: electric machine engineering. SUBSTANCE: stator of high-voltage electric machine has core of magnetic circuit 1 in which slots rigid template coils 2 are located. Coils have insulation 4 made of dry glass-and-mica belts and outer semiconducting coat 6 impregnated and baked in epoxy compound after laying. Insulation box 5 is placed between semiconductor coat and insulation. Thickness of box is chosen from condition , where B is clear dimension of slot, mm; b is dimension of conductive part of coil over width with allowance for turn insulation, mm; 4 is parameter taking into account application of belt with 1/2 overlapping, n is number of layers of body insulation; δ_b is thickness of belt, mm; ε is summary thickness of conductive coat, mm. EFFECT: facilitated manufacture, enhanced operational characteristics. 4 dwg
