DRG MOTOR – High-Efficiency Electric Motors
“More Power with Less Energy.”

What is a High-Efficiency Motor? Why is it Important?
Energy is now a strategic resource for every industry.
Electric motors consume more than 65% of industrial electricity worldwide.
Therefore, every improvement in motor efficiency directly translates into cost savings and reduced carbon emissions.

High-efficiency electric motors are defined according to the IEC 60034-30-1 standard and include IE3, IE4, and IE5 efficiency classes.
Compared to conventional motors, these motors:

  • Consume less energy,

  • Generate less heat,

  • Operate more quietly,

  • Have a longer service life.

As of 2024, according to Ecodesign regulations in Turkey and the European Union,
IE3 efficiency is mandatory for all motors above 0.75 kW.

DRG MOTOR high-efficiency series (IE3 – IE4 – IE5)
offers energy savings and industrial sustainability together.

DRG MOTOR High-Efficiency Motor Technology

Efficiency Engineering
DRG MOTOR series are designed with every detail to maximize energy efficiency:

  • High-quality silicon steel laminations reduce magnetic losses.

  • 100% pure electrolytic copper windings minimize resistance losses.

  • Optimized air-gap design increases magnetic flux density.

  • Vacuum impregnation strengthens winding insulation.

Production Quality and Material Features:

  • Body: Cast Iron (GG20)

  • Shaft: C45 Carbon Steel

  • Cover: Cast Iron

  • Bearings: SKF / C&U / NSK

  • Paint: Electrostatic powder coating (RAL 7032, 6028, 5012)

  • Insulation Class: F Class (155°C)

  • Protection: IP55

Every component in high-efficiency motors is selected to reduce heat, enhance silence, and optimize energy conversion.

Energy Efficiency and Different IE Classes

IE3 – Premium Efficiency

  • Provides 8–10% energy savings over conventional industrial motors.

  • Mandatory in Turkey for 0.75 kW and above.

  • Quiet, balanced, long-lasting.

IE4 – Super Premium Efficiency

  • 3–5% more efficient than IE3.

  • Low-loss rotor and optimized stator reduce heat.

  • Quiet operation (55–70 dB) and low vibration (≤1.5 mm/s) make a difference.

IE5 – Ultra Premium Efficiency

  • The most advanced motor class.

  • 3–4% more efficient than IE4, up to 15% additional energy savings.

  • Compatible with IoT systems and inverter-controlled operation.

  • Industry 4.0 ready, long-lasting, ultra-quiet.

DRG MOTOR provides stock-ready motor solutions for all IE classes in the 0.55 – 355 kW range.

Noise and Vibration Performance

Silence is as important as energy savings in high-efficiency motors.
DRG MOTOR series are manufactured with acoustic balance, vibration control, and excellent balance tolerance (G 2.5).

Noise Levels (dB(A)):

Efficiency Class   Noise Range     Description
IE3    58–75 dB(A)Standard Premium Motor
IE4    55–70 dB(A)Super Premium Efficiency
IE5    52–68 dB(A)Ultra-Quiet Motor Design

Vibration Levels (mm/s – RMS):

Motor Class      Vibration Value    Standard
IE3≤1.8 mm/sISO 10816 N Class
IE4≤1.5 mm/sISO 10816 R Class
IE5≤1.0 mm/sHigh Precision Balance

Noise and vibration tests are conducted according to EN 60034-9 and ISO 10816 standards.
Each motor undergoes dynamic balance testing before leaving the factory.
