Description
Medium-voltage SG series motors for shearer loaders and face crushers are intended for powerful mechanised complexes, where supplying the shearer at 3.3 kV (and in some cases 4.16 or 6 kV) makes it possible to reduce currents, cable cross-sections and voltage losses on long longwalls. The motors are squirrel-cage induction motors with water-cooled frames, in a flameproof version for underground workings. The range is from 100 to 1000 kW. Most types are produced at 3300 V; some at 3300 and 4160 V (SG8 555X-4, 2SG3W 760Y-4A) or 3300 and 6000 V (3SG4W 562Y-4). The motors are four-pole with a rotational speed of about 1465–1486 rpm; the 2SG3W versions are rated for 50 and 60 Hz (1482/1782 rpm). Degree of protection IP55 or IP66. Duty types are S1, S4-60 % with 40 starts per hour, S6-50/60 % and S2 60 min, according to the cutting-head cycle. Examples of types: SG3 535X-4A — 100 kW; SG8 555X-4 — 110–175 kW (3300/4160 V); SG4W 562X-4 — 250 kW; SG8W 562Y-4B — 400–450 kW; SG3W 760Y-4 — 500 kW; 2SG3W 760Y-4A — 580–630 kW; SG6W 598X-4A — 630–650 kW; SG6B 764Y-4 — 750 kW; SG6B 874X-4 — 850 kW; SG6B 874X-4A — 1000 kW. The item is an analogue of the powerful 3.3 kV shearer loader motors used at mines in Ukraine and Poland.
