Motors for roadheaders, continuous miners, shuttle cars and plows, up to 11 kV, up to 2000 kW

Description

This position combines special flameproof motors for mining roadheaders and other auxiliary mining equipment: roadheaders (road headers), continuous miners, bolter miners, shuttle cars and plows. For continuous miners and shuttle cars the manufacturer produces drives for travel, conveyors, cutting, hydraulics and loading arms. The motors are designed for the maximum possible power within a given frame, because the space in the driven machines is limited, and are made to the customer's exact mounting dimensions. Plow motors are designed for one of the most severe duty cycles in mining equipment: a high frequency of repeated starts and reversals requires an especially strong rotor, so water-cooled frames, end shields and, on request, the rotor are used, and the Barlok rotor design prevents bar breakage by letting the bars expand freely and avoiding stress concentration. General parameters of the mining range: power up to 2000 kW, voltage up to 11 kV, 2, 4, 6 and 8 poles, air cooling, water jacket or forced ventilation, foot-mounted and/or flanged design, direct-on-line or VFD operation with insulated bearings. In addition, the manufacturer supplies motors for bucket loaders, tunnel boring machines, mining locomotives and monorail systems.
