The power range needed in industry is very wide; sometimes a drive of a few hundred watts is required, sometimes a main motor of hundreds of kilowatts. At DRG Motor we build both high- and low-kW electric motors to the same quality line, meeting these different needs from a single point. The correct power selection directly affects both efficiency and motor life.

The Relationship Between Power and Torque

A motor's power depends on the product of the torque it produces and its speed. At the same power, a low-speed motor produces higher torque while a high-speed motor delivers lower torque. For this reason, even a low-kW motor can meet an application's torque demand when chosen at the right speed.

Low-kW Applications

Low-power motors are used on small pumps, dosing systems, fans and automation mechanisms. Compact size, quiet running and energy efficiency are the priorities in this segment. An aluminium frame, light and with good cooling, is often preferred.

High-kW Applications

High-power motors come into play on compressors, large pumps and heavy machine drives. Here mechanical strength, high torque and efficiency under sustained full load are what matter. A cast iron frame provides reliability under vibration and temperature.

Selecting the Right Power

An oversized motor runs inefficiently at light load, while an undersized one overheats. Izmir-based DRG Motor identifies the model best matched to the power and speed of your application across the 0.55-355 kW range and provides a current quotation.
