DRG MOTOR 1.1 kW 1500 rpm NEXT GENERATION ELECTRIC MOTOR

The DRG Motor 1.1 kW 1500 rpm Next Generation Electric Motor is a compact yet high-performance model designed to deliver high efficiency, low energy consumption, and stable operation for small and medium-scale industrial applications. This power range is especially preferred in fan systems, ventilation units, water pumps, light conveyor lines, compressors, agricultural machinery, and small drive mechanisms. Thanks to its 1500 rpm speed structure, the motor produces balanced torque while ensuring low-vibration, quiet, and reliable operation.

This model is manufactured in compliance with S1 continuous duty standards, making it ideal for applications requiring long-duration operation under load. Even during extended working cycles, it maintains stable performance without efficiency loss. With its IE2–IE3 efficiency design, it offers a perfect balance of durability, performance, and energy savings.

Structural Design and Durability Features

The DRG Motor 1.1 kW model offers high durability against impacts, vibration, and harsh conditions thanks to its cast-iron GG20/GG25 body. The advanced cooling fins on the frame ensure that the motor maintains its optimal temperature even under intensive operation.

The windings are manufactured from 100% electrolytic copper, and the vacuum impregnation technique provides strong insulation against heat and moisture. The rotor is built with special alloy bars that minimize magnetic losses and improve torque efficiency.

SKF / C&U bearings offer long service life and superior friction resistance. Double-lip seals protect the internal system from dust, moisture, and particles. The electrostatic powder paint provides excellent resistance against chemicals, abrasion, and environmental effects.

The IP55 protection class allows the motor to operate safely in dusty and humid environments.

Performance, Torque, and Efficiency

The DRG Motor 1.1 kW 1500 rpm model produces balanced torque, especially under low and medium load conditions. It maintains stability during frequent start-stop cycles without drawing excessive current.

The rotor is balanced according to G 2.5 standards with a vibration level of ≤1.8 mm/s under ISO 10816. This reduced vibration level extends bearing life, provides quieter operation, and reduces mechanical wear.

Thermal characteristics:

  • Maximum thermal rise: <70K

  • Maximum winding temperature: 105°C

  • Maximum bearing temperature: 75°C

Optional PTC/PT100 sensors can be added for advanced temperature monitoring.
