The DRG Motor 11 kW 3000 rpm electric motor is a high-speed three-phase induction motor with a 2-pole construction. On a 400 V / 50 Hz supply, this class has a synchronous speed of 3000 rpm and stands out in pump, compressor and high-speed fan applications. At 11 kW, it sits in a common power band for mid-sized loads.

Technical Specifications and Speed Structure

The 2-pole winding produces a synchronous speed of 3000 rpm on a 50 Hz supply; the actual speed under load is slightly below this value because of slip. The high speed delivers efficient power transfer in loads that demand high flow and pressure, such as centrifugal pumps and compressors. The motor is built with IP55 protection and Class F insulation, suited to S1 continuous duty.

Cast Iron Frame and Durability

The cast iron frame damps the vibration generated at high speed and protects the service life of the bearing arrangement. Since balance quality and bearing selection are critical at speeds as high as 3000 rpm, the motor is supplied with a balanced rotor and suitably preloaded bearings, keeping noise and wear low.

Where Is It Used?

The 11 kW 3000 rpm motor is used in pressurisation pumps, vacuum pumps, small-to-medium air compressors and high-speed radial fans. Depending on the mounting need, B3 foot, B5 flange or B14 face versions can be chosen, making the motor directly compatible with different machine housings.
