High-capacity electric motors form the backbone of mechanical work in production lines, pumping stations and power facilities that demand significant output. These motors are built to deliver high torque and stable operation under continuous load, and are typically manufactured with a cast iron frame in power ratings above 55 kW.

What Does High Capacity Mean?

Capacity describes the rated power (kW) of the motor together with its ability to deliver torque and handle starting current. Motors running at 75, 110, 160 or 250 kW comfortably drive high-inertia loads such as conveyors, crushers and fans. DRG Motor supplies this class up to 355 kW.

Frame and Cooling Design

At higher outputs, heat management becomes decisive. The cast iron frame offers strong resistance to both mechanical impact and vibration, while IC411 surface cooling fins dissipate heat. Class F insulation and IP55 protection allow continuous duty (S1) in dusty and humid environments.

Speed and Torque Balance

The pole count is chosen according to the application: 4-pole motors at 1500 rpm suit general-purpose drives, while 6-pole models at 1000 rpm are preferred in crushing and screening lines that demand high torque. Matching pole count to speed correctly directly affects both energy use and mechanical service life.
