Product Description

YTM, YHP, YMPS series large squirrel cage motors are high-voltage squirrel-cage motors specially designed for driving coal mills. These series of motors are box-type structures. The bases are welded by steel plates, which are light in weight and good in rigidity. The closed cooler is installed on the top of the motor, which is convenient to disassemble and facilitate the maintenance and repair of the motor.
YTM, YHP, YMPS series large squirrel cage motor stator windings use Class F insulation, reliable fixed binding at the end, and adopts the introduction of Germany's advanced vacuum pressure impregnation solventless paint process (VPI). Therefore, the motor has excellent insulation performance. Reliable, good mechanical strength and good moisture resistance.
YTM, YHP, YMPS series large squirrel cage motors adopt advanced and reliable cast aluminum rotor structure to ensure the reliability of motor operation. YHP, YMPS series motors use a copper bar rotor structure to ensure the high starting torque of the motor.
YTM, YHP, YMPS series large squirrel cage motors are suitable for various coal mills in power stations, mines, metallurgy and other industries, and can also be used to drag other mechanical equipment with similar characteristics.
