Explosion-proof electro-motors

TYPE dS(K,L)g

Three-phase explosion-proof electro-motors with a short-circuit armature, type dS(K,L)g are determined to drive machines and devices, e.g. fans, pumps, grinders, hydraulic sets, conveyors etc. in gassy mines in areas with high explosion hazard of methane and coal dust. These motors can be used as a direct drive or in a configuration with a gear-box. The motor can be be started with a direct switch-on or via soft-start. Concerning design, the motor are manufactured in three versions: butt-mounted, flange-mounted or butt-mounted with a flange. In the standard version the motors are delivered for voltage of 500V or 1000V, however on request the manufacturer also delivers motors for the voltage of 660V, eventually 1140V. As standard, the motors are equipped with thermal sensors in the winding and in bearings and on request they may be fitted with bimetallic or thermistor sensors, eventually with thermocouples. The connecting boxes are fitted with an end-component for monitoring of the ground-conductor integrity. The motors of the stated type are manufactured in the the power line from 4kW up to 160kW, namely as 2-poles up to 8-poles.

The stated electro-motors have got the ES Certificate of ATEX Type test and they are approved by the state mining authority for use in gassy mines, in areas with high explosion hazard of methane and coal-dust.
