Description
Two-speed water-cooled medium-voltage motors are intended for drives of powerful face scraper conveyors and transfer units. Two independent stator windings — with 12/4 or 8/4 poles — provide starting of a heavily loaded conveyor at low speed with increased torque and subsequent operation at rated speed; the starting currents and dynamic loads on the chain and gearbox are thereby reduced. The range covers powers from 85/250 to 400/800 kW at a voltage of 3300 V. Rotational speeds are about 492–494/1485–1493 rpm for the 12/4 versions and about 736–743/1485–1493 rpm for the 8/4 versions. Degree of protection — IP55, and IP66 or IP67 for some types. Duty types — S1 and S4-60 % with 40 to 150 starts per hour, which reflects the heavy duty of a face conveyor. Examples of types: SG3 450X-12/4 — 85/250 kW; SG3 400X-8/4 — 100/200 kW; SG1(2,3) 450Y-12/4 — 135/400 kW; SG1(2,3) 450Y-8/4 — 200/400 kW; SG3 500X-12/4A — 210/630 kW; SG1(2,3) 450Y-8/4A — 260/520 kW; SG3 560X-12/4A(f) — 265/800 kW; SG3 500X-8/4B — 350/700 kW; SG3 560X-8/4A(f) — 400/800 kW. The motors are made in a flameproof version for underground workings. The item is an analogue of two-speed face conveyor motors at 3.3 kV.
