The high kW electric motor is the core drive source for large-scale industrial facilities, energy-intensive machines and heavy-duty applications. It delivers reliable performance in applications requiring high torque and uninterrupted operation, such as crushers, mills, large pumps, compressors and fan systems. DRG Motor builds this segment across a wide range from 30 kW up to 355 kW.

Mechanical Strength at High Power

High kW motors produce high torque and vibration; a cast iron frame is preferred to carry this load. Cast iron provides mechanical strength and vibration damping for long life in heavy industrial conditions. IP55 protection and Class F insulation allow safe operation in dusty, humid and hot environments.

Speed Choice and Application

The pole count is determined by the torque and speed the application requires: crushers and mills favour 4-pole 1500 rpm or 6-pole 1000 rpm, while centrifugal compressors use 2-pole 3000 rpm. The correct pole choice keeps the motor running at its rated efficiency with low vibration.

The Importance of the Efficiency Class

At high power, the saving created by the efficiency class grows. IE3 Premium and IE4 Super Premium motors run with lower losses under IEC 60034-30-1 and save thousands of kWh per year in continuously operating plants. For this reason, in high kW applications the high efficiency class determines the total cost.

DRG Motor in High kW Motors

In heavy industry, the motor is the most critical component determining production continuity. DRG Motor builds cast iron motors in IE2/IE3/IE4 classes from 30 to 355 kW for S1 continuous duty and supplies them from Izmir. Contact us for power and speed matching.
