DRG motors rated at 250 kW and 3000 rpm are built for heavy-duty applications that demand both high speed and high power. Thanks to their 2-pole design, these motors deliver a speed close to synchronous on a 50 Hz supply, enabling direct drive of compressor, pump and fan sets.

The 2-Pole High-Speed Design

On a 50 Hz supply, the synchronous speed of a 2-pole motor is 3000 rpm; with slip, it settles around 2950 rpm under load. The high speed allows rotating equipment to be driven with fewer gear stages, reducing mechanical losses. At the 250 kW level this delivers a meaningful efficiency advantage.

Cooling and Mechanical Strength

Heat management is decisive at high speed. DRG's 250 kW motors are produced with Class F insulation and IP55 protection; the cast iron frame damps high-speed vibration and protects bearing life. They are dimensioned to run continuously at full load under an S1 duty cycle.

Typical Applications

250 kW 3000 rpm motors are favoured in centrifugal pumps, screw compressors, high-flow fans and granulation lines. Because these applications benefit directly from high speed, the need for an intermediate gearbox is reduced.

Matching the Motor to the Application

A 250 kW 3000 rpm motor is not right for every job, but it is the correct choice for heavy loads that require high speed. The İzmir-based supplier DRG Motor determines pole count and mounting type by application across the 0.55-355 kW range to offer the most suitable solution.
