The cast iron frame is the key element that determines the durability and quietness of electric motors working in heavy industrial conditions. DRG Motor's next-generation cast iron-framed models combine high mechanical strength with low vibration and noise.

The Advantage of a Cast Iron Frame

Cast iron has greater mass and damping capacity than an aluminium frame. As a result, the motor vibrates less and runs quieter under high torque and sudden load changes. In heavy-duty applications it resists impact and mechanical stress.

Heat Management and Service Life

The surface area and fin structure of the cast frame ease heat dissipation. Combined with Class F insulation and IP55 protection, the winding temperature is kept under control, extending bearing and winding life. It runs safely at full load under an S1 continuous-duty cycle.

Efficiency Classes and Power Range

Next-generation cast iron-framed motors are produced in IE3 Premium and higher efficiency classes, combining high strength with low energy consumption. Speed ranges of 3000, 1500 and 1000 rpm are offered with 2-, 4- and 6-pole options.

The Right Frame for Heavy Industry

In dusty, vibrating and continuously operating environments, the cast iron frame is the safest choice. The İzmir-based supplier DRG Motor supplies cast iron-framed motors with B3/B5/B14 mounting in the 0.55-355 kW range according to the application.
