The 355 kW 1000 RPM electric motor, engineered by DRG Motor, is a high-performance industrial motor tailored for demanding applications that require high torque, continuous operation, and exceptional reliability. Designed for longevity and built to withstand harsh operational environments, this motor stands as a powerful solution for facilities seeking efficient, stable, and low-maintenance power systems. It combines engineering precision with robust construction and energy efficiency—making it ideal for modern industrial setups.

Operating at 355 kilowatts of power and 1000 revolutions per minute, this motor is optimized for heavy-load applications where low speed and high torque are required. These include cement plants, heavy-duty crushers, large industrial mixers, mining machinery, press systems, massive ventilation fans, and pumping systems. Its ability to deliver strong torque at startup ensures a smoother launch of connected machinery, reducing stress on mechanical components and improving operational safety.

The motor’s frame is manufactured from high-strength GG25 cast iron, which offers excellent resistance to mechanical stress, temperature variations, and environmental conditions. It comes with IP55 protection as standard and can be upgraded to IP65 for dusty, humid, or water-exposed environments. Internally, the motor is equipped with high-purity copper windings, low-loss laminated cores, and insulation in Class F or H, ensuring optimal performance even at elevated temperatures and under heavy load conditions.

From an energy efficiency perspective, the motor meets IE3 efficiency standards, with optional availability in IE4 high-efficiency class. Especially at 355 kW, this efficiency translates into significant annual energy savings and lower operational costs. It also aligns perfectly with sustainability and carbon reduction targets for large-scale industrial facilities.

Installation options include B3 (foot-mounted), B5 (flange-mounted), and B35 (foot + flange combination) types. Custom configurations can be provided for shaft diameter, flange dimensions, terminal box orientation, and other critical parameters—allowing the motor to be tailored to your exact requirements. It is fully compatible with VFDs (Variable Frequency Drives), enabling precise speed and torque control and further enhancing process efficiency.

Optional features include PTC thermistors, PT100 sensors, encoders, electromagnetic brakes, and automatic lubrication systems. For hazardous environments, ATEX-certified explosion-proof models are available, offering safe operation in areas with flammable gases or dust and full compliance with international safety standards.

Maintenance has been a key consideration in the motor’s design. With a spacious terminal box, high-quality bearings, dynamically balanced rotor construction, and support for automatic greasing, the motor is built to run for extended periods without unplanned downtime. It reduces the frequency of maintenance intervals and ensures stable performance throughout its lifecycle.

In summary, the 355 kW 1000 RPM electric motor by DRG Motor offers more than just power—it provides a strategic industrial advantage through durability, adaptability, and efficiency. It is a smart, long-term investment for companies aiming for uninterrupted productivity and sustainable operation in high-demand environments.
