250 KW 1000 RPM ELECTRIC MOTOR

CONTACT: +90 542 666 11 11

The 250 kW 1000 RPM electric motor, developed by DRG Motor, is an industrial-grade power unit specifically engineered for heavy-duty applications requiring high torque and continuous reliability. This motor is designed to meet the performance expectations of industries operating under extreme mechanical stress and prolonged work cycles. With its optimized structure, energy efficiency, and robust construction, it stands as a reliable solution for enterprises looking to maximize productivity while minimizing operational and maintenance costs.

With a power output of 250 kW and a low rotational speed of 1000 RPM, the motor provides exceptionally high torque at startup and maintains consistent performance under heavy loads. Its low-speed operation reduces wear and vibration, leading to longer equipment life and reduced need for maintenance. It is ideally suited for applications such as cement factories, crushers, conveyors, mixers, high-power fans, water pumping stations, mining equipment, and heavy lifting systems.

The housing is made from high-strength GG25 grade cast iron and designed to resist mechanical shock, environmental conditions, and vibration over years of operation. It is offered with IP55 protection as standard, and higher protection ratings like IP65 are available upon request. Inside the motor, high-purity copper windings, optimized stator and rotor structures, and low-loss magnetic materials ensure high operational efficiency. With insulation classes F or H, the motor remains stable and safe even under elevated thermal conditions.

In terms of energy efficiency, the motor complies with the IE3 efficiency class, with IE4 versions available for energy-critical projects. This enhanced efficiency is especially important in high-power motors like this, significantly reducing annual energy consumption and operational costs, while also supporting sustainable energy practices.

The motor offers flexible mounting configurations such as B3 (foot-mounted), B5 (flange-mounted), and B35 (combined). Custom options are available for shaft diameter, flange dimensions, and terminal box orientation. It is fully compatible with frequency inverters (VFDs), allowing for precise control of speed and torque—an essential requirement for modern automated industrial systems.

A variety of optional features can be integrated, including PTC thermistors, PT100 sensors, encoders, and electromagnetic brakes. Furthermore, ATEX-certified explosion-proof versions are available for operations in hazardous environments, ensuring compliance with international safety regulations.

As with all DRG Motor products, ease of maintenance is a key design feature. The motor includes a spacious terminal box for convenient wiring, high-grade bearing systems, dynamically balanced rotors for smooth operation, and long greasing intervals. It can also be equipped with automatic lubrication systems, which minimize unplanned downtime and improve overall reliability.

In conclusion, the 250 kW 1000 RPM electric motor is more than a power device—it is an industrial powerhouse built with precision engineering, durability, and performance at its core. It represents DRG Motor’s commitment to quality, efficiency, and long-term value.
