A 37 kW asynchronous motor corresponds to roughly 50 horsepower and is a power class frequently met in medium-to-large industrial applications. On pump, compressor and conveyor drives, this rating sits at a balanced point between capacity and durability.

Where the 37 kW Class Is Used

This power class drives medium-flow centrifugal pumps, screw compressors, large ventilation fans and heavy conveyor lines. At 37 kW, a motor is strong enough to drive a single line yet sized to stay efficient without being oversized.

Speed and Pole Options

A 37 kW motor can be specified as 2-pole 3000 rpm, 4-pole 1500 rpm or 6-pole 1000 rpm depending on the application. Higher speed suits pumps and compressors, while lower speed is preferred for conveyors and mixers that need high torque.

Construction and Protection Features

37 kW asynchronous motors are typically built with a cast iron frame, IP55 protection and Class F insulation, in B3 foot-mounted or B5 flange-mounted form. The IE3 Premium efficiency class clearly affects energy cost on a motor of this size running continuously.

Making the Right 37 kW Choice

DRG Motor supplies 37 kW asynchronous motors in various pole and frame options, configured for a 400 V / 50 Hz supply. We determine the most suitable configuration together, based on your application's load and speed profile.
