DRG MOTOR 355 kW 1000 rpm NEXT GENERATION ELECTRIC MOTOR

Contact: +90 (542) 666 11 11

The DRG Motor 355 kW 1000 rpm Next Generation Electric Motor is a high-performance motor series that combines maximum power, high torque capacity, and long-lasting operational standards required by heavy-duty industrial facilities. This model is specially optimized for crushing and screening plants, high-capacity conveyor lines, industrial mixers, large-volume pumps, gearbox-driven systems, and all types of heavy industrial applications that require continuous operation.

The 1000 rpm low-speed structure provides stable and efficient power transmission in machines that require high torque under heavy load. Thanks to its low-speed – high-torque balance, the motor operates extremely stable both during startup and during sudden load changes. Its energy efficiency is designed in accordance with IE3 and IE4 classes, providing significant long-term energy savings for industrial plants.

Structural Design and Durability Features

The 355 kW 1000 rpm model of DRG Motor is designed to withstand heavy impacts, intense vibration, and challenging environmental conditions thanks to its cast-iron body (GG20/GG25) and reinforced carrier structure. The cooling fins on the body create an optimized airflow that keeps the motor temperature balanced even during continuous operation.

The windings are manufactured from 100% pure electrolytic copper, and vacuum impregnation provides long-lasting insulation against heat and humidity. The rotor cage structure consists of special alloy bars, offering high torque transmission, low losses, and low vibration performance.

SKF / C&U bearings are lubricated with high-temperature resistant grease to ensure reliable performance during long-term duty cycles. Double-lip seals provide strong protection against dust, mud, and moisture. The paint coating is an electrostatic powder paint resistant to chemicals and abrasion.

Thanks to its IP55 protection class, the motor can be safely used in dusty, humid, muddy, and harsh environmental conditions.

Performance, Torque, and Energy Efficiency

The 355 kW 1000 rpm motor provides safe startup even under heavy loading thanks to its high starting torque. It delivers stable performance without drawing excessive current during stop-start duty cycles frequently encountered in industrial facilities.

Its low-speed structure meets the torque requirements of gearbox-driven systems with minimal loss. The rotor balance is made according to G 2.5 standard, with a vibration level of ISO 10816 ≤1.8 mm/s. This minimizes fatigue on bearings, end shields, and mechanical components.

Thermal performance is at a high level:

Maximum thermal rise: <75K
Maximum winding temperature: 110°C
Maximum bearing temperature: 80°C

If requested, PTC / PT100 temperature sensors can be integrated to enable advanced thermal monitoring.

Testing Stages and Quality Standards

The DRG Motor 355 kW series undergoes a comprehensive testing process before shipment:

Full-torque load test
Insulation resistance test (500V Megger)
Rotor balance test (G 2.5)
Noise and vibration analysis (EN 60034-9 / ISO 10816)
Continuous duty (S1) test – minimum 2 hours at nominal load
IP55 dust and water resistance tests
Electrical current – power – loss analysis

Motors that successfully pass all these tests are prepared for shipment after a final inspection.
