The DRG Motor 220 kW 1500 rpm industrial electric motor is a 4-pole asynchronous machine built for heavy-duty applications on a 400 V / 50 Hz supply that demand high torque. Manufactured in Izmir, DRG combines durability and efficiency at this power rating.

The 220 kW Frame and Mechanical Build

At this power level the frame is made of cast iron, which damps operating vibration and carries heat to the outer surface, extending bearing life. The IP55 protection rating shields the windings against dust and water jets. The standard mounting is foot-mounted B3, with a B5 flange option for pump and fan duties.

1500 rpm Speed and Torque Behaviour

The 4-pole winding produces a synchronous speed of 1500 rpm on a 50 Hz supply; under load the actual speed runs slightly below this due to slip. Pairing 220 kW with 1500 rpm yields roughly 1400 Nm of rated torque, the balanced speed-torque profile sought in crushers, extruders, compressors and large fan drives.

Efficiency Class and Insulation

The motor is built to the IE3 Premium efficiency class under IEC 60034-30-1; Class F insulation withstands a winding temperature of 155 °C and operates continuously under full load in the S1 duty cycle. At this rating, high efficiency makes a clear difference in annual energy consumption.

Sourcing the 220 kW Motor from DRG
