Description
Heavy-duty heading machines (roadheaders) working in mines with a 1140 V network require cutting-head and auxiliary drive motors for this voltage. In the catalogue almost all motors for heading machines and crushers from 13 kW upward are offered at 1100 and/or 1140 V; this item combines exactly these versions. Small 1140 V types: 3SGK 160S-4 — 13 kW, 3SGKH 200S-4 — 15 kW, 2SG4 225S-4 — 36 kW. The main part consists of water-cooled motors of 100–315 kW, many of which are produced only at 1000/1100/1140 V: SG6 570M-4A — 150 kW, SG4 562S-4 — 200 kW, SG4B 575M-4A — 280 kW, SG3V 600L-4 — 300 kW, SG3V 450L-4A — 315 kW. For driving the cutter head, two-speed 8/4-pole motors are intended, produced only at 1000/1140 V: SG9C 520M-8/4A — 75/132 kW, SG9C 660M-8/4A — 110/200 kW, SG4 720M-8/4A — 150/250 kW, SG4C 740L-8/4B — 200/260 kW (IP66), with speeds of about 738/1480 rpm and S4-60 % duty up to 60 starts per hour. Flameproof motors are rated for the heavy intermittent duty of heading machines. The item is an analogue of the 1140 V heading machine motors.
