An industrial electric motor is a three-phase asynchronous motor that, unlike workshop or light-duty motors, is built with a reinforced housing, insulation and bearing arrangement to run under continuous load in harsh conditions. The uninterrupted running of production lines depends on the durability of these motors.

What Sets the Industrial Type Apart

Industrial motors are typically built with a cast iron housing, which gives higher resistance to vibration and mechanical impact. Class F insulation leaves a safety margin against high winding temperature, and IP55 protection guards against dust and splashing water.

Suitability for Continuous Running

The S1 continuous duty rating defines a thermal design under which the motor can run indefinitely at rated load. For a motor working all day in shift-based production, this rating together with proper cooling determines its life.

Choosing Power, Speed and Efficiency

On a 50 Hz supply, 2 poles give 3000 rpm, 4 poles 1500 rpm and 6 poles 1000 rpm of synchronous speed. IE3 Premium and higher efficiency classes cut the electricity cost of a continuously running industrial motor and lower its total cost.

Choosing the Right Industrial Motor

DRG Motor supplies industrial asynchronous motors from 0.55 to 355 kW with B3 foot and B5 flange mounting and cast iron housing options. Send us your application's load and speed profile, and we will set the right motor and a current quote together.
