YTM, YHP and YMPS series high voltage 3-phase induction motors for coal mills are one new series products designed and developed by our company according to JB/T7128 Industry Standard of the Ministry of machinery. This series motors have the characteristics of large locked rotor torque and large heat capacity. The enclosure protection degree is IP54, the rated voltage is 6kV, and it can also be made into 3KV. The cooling method is IC511, IC611 or IC81W. In recent years, it has been proved by many users all over the country that this series motors work normally, safe and reliable.

Technical information:

H355-710, Power:220-4500kW, Protection Degree: IP44、IP54、IP55, Insulation Class: F, Cooling method: CodeIC511, IC611，IC81W, Ambient Temperature of -15℃~+40℃, Altitude not exceeding 1000m above sea level。Performance parameters and installation dimensions of this series motor is the same as YKK series with the same voltage level. 

Main Feature and standards compliance: 

 YTM, YHP and YMPS series motors adopt box structure. The frame is welded with steel plate, light weight and good rigidity. A closed cooler is installed on the top of the motor, which is convenient for disassembly and repair.YTM series motor adopts advanced and reliable cast aluminum rotor structure to ensure the reliability of motor operation. YHP and YMPS series motors adopt copper bar rotor structure to ensure high starting torque.

Application range and operating environment:

 YTM, YHP and YMPS series motors are specially used for various coal mills in power station, mining, metallurgy and other industries, and can also be used for other mechanical equipment with similar driving performance.
