In production facilities, conveyors, crushers, large pumps and air systems are usually driven by medium and high-power electric motors. Because the choice of these motors directly affects downtime, energy cost and maintenance load, the decisions on power, speed and frame material should be made correctly from the start.

Power Range for Plant Loads

Light conveyor and fan duties are covered by a few kW, while crushing and screening, large water pumps and air-handling units can climb into the 30–355 kW band. DRG Motor covers this wide range with three-phase asynchronous motors suited to a 400 V / 50 Hz supply, so even the toughest load on the line can be sized from a standard product at the right power and speed.

A Build Made for Continuous Duty

Plant motors mostly run on the S1 continuous duty cycle, turning without stopping throughout a shift. For this, a cast iron housing, IP55 protection and Class F insulation are essential: cast iron provides a stable structure against both mechanical impact and constant heat, while IP55 protects the windings from dust and splashing water.

Speed Choice and Energy Cost

On pumps and fans, choosing between 2-pole (3000 rpm) and 4-pole (1500 rpm) sets both the flow and the energy use. On heavily loaded lines, stepping up from IE3 to the IE4 efficiency class brings visible savings in the electricity the motor consumes over its life, so the decision should rest on total operating cost rather than the label price alone.

Picking the Right Motor for Your Facility

DRG Motor supplies motors from 0.55 to 355 kW with B3/B5/B14 mounting options for the pumps, fans, compressors and handling systems on plant lines. Once you share the load character, running hours and mounting type, we determine the most suitable power and efficiency class for your line together.
