DRG MOTOR 1.5 kW 1500 rpm NEXT GENERATION ELECTRIC MOTOR

The DRG Motor 1.5 kW 1500 rpm Next Generation Electric Motor is designed to deliver high efficiency, low energy consumption, and long service life for small and medium-scale industrial applications. This power range is widely preferred in fan systems, water pumps, light conveyor lines, ventilation units, compressors, textile machines, agricultural machinery, and packaging systems. Thanks to its 1500 rpm speed structure, the motor ensures balanced torque production and low-vibration, quiet, stable operation.

This motor is manufactured according to the S1 continuous duty class, providing reliable long-term operation without overheating or performance loss. Its IE2–IE3 efficiency rating plays a key role in reducing energy costs while maintaining strong performance in a compact structure.

Structural Design and Durability

The DRG Motor 1.5 kW model features a robust GG20/GG25 cast-iron body that ensures high durability against impact, vibration, and harsh environmental conditions. Advanced cooling fins optimize heat dissipation, allowing stable performance during continuous operation.

Windings are made of 100% electrolytic copper and vacuum-impregnated to provide resistance against heat, moisture, and vibration. The rotor incorporates special alloy bars with a low-loss magnetic design that improves torque efficiency.

SKF / C&U bearings ensure long service life. Double-lip seals provide protection against dust, moisture, and contaminants. Electrostatic powder coating delivers long-term resistance to chemicals and outdoor conditions.

The IP55 protection rating guarantees reliable operation in dusty and humid industrial environments.

Performance, Torque, and Efficiency

The DRG Motor 1.5 kW 1500 rpm model delivers strong torque with minimal energy consumption. Even during frequent start-stop cycles, the motor maintains stable current and torque output.

The rotor is dynamically balanced to G 2.5 standards, resulting in vibration levels ≤1.8 mm/s according to ISO 10816. This ensures smoother operation and longer mechanical lifespan.

Thermal characteristics:

  • Maximum thermal rise: <70K

  • Maximum winding temperature: 105°C
