ASYNCHRONOUS TRACTION ELECTRIC MOTORS, EXPLOSION-PROOF THREE-SPEED DATV (M)-270
Asynchronous traction motors, three-speed, explosion-proof, three-phase alternating current with a short-closed copper-soldered rotor DATV(M) type)-270 are designed for operation on AC 50 Hz with a rated voltage 660 V or 1140 V with repeated short-term operation mode S4 in underground workings of coal, potash and shale mines, dangerous for gas and dust, at an ambient temperature of 35° C and a relative humidity of 97 %.
The engines are components for driving the course of self-propelled wagons with a load capacity of 15 t and 30t, as well as for use as part of hoppers-reloaders.
