The high-kW electric motor is the core drive element of heavy industry, large-scale production lines and facilities with intensive energy demand. In this power class, DRG Motor supplies motors that combine durability and efficiency, running effortlessly under continuous load.

Design Priorities in the High-kW Class

As power increases, so do the mechanical stresses and thermal load on the motor. DRG's high-kW motors use a cast iron frame, reinforced bearing housings and balanced rotor assembly. This keeps vibration low and extends bearing life at outputs such as 90, 132 and 200 kW.

Efficiency Class and Operating Cost

In high-power motors the efficiency gap translates into a significant annual energy bill. Under IEC 60034-30-1, the IE3 Premium and IE4 Super Premium classes substantially cut losses compared with IE1. On a continuously running 160 kW motor, this difference means savings many times the purchase price of the motor.

Mounting and Connection Options

DRG high-kW motors are supplied in foot-mounted B3, flange-mounted B5 or combined B35 forms. Built for 400 V / 50 Hz supply with Class F insulation and IP55 protection, they integrate easily into gearbox, pulley or direct-coupling applications.

Choosing the Right High-kW Motor

Power demand must be assessed not only at the operating point but also under starting and continuous-load conditions. Across its 0.55 kW to 355 kW range, DRG Motor defines the suitable pole-speed and frame combination with you. Reach out to the DRG Motor team for a detailed quotation.
