Why Choose DRG MOTOR

The electric motor is the heart of industrial systems.
A motor should not only rotate — it must add value to production, save energy for the facility, and operate reliably for years.

DRG MOTOR was founded with this philosophy.
We adopt a quality approach that exceeds European standards in material quality, engineering design, manufacturing tolerances, energy efficiency, and testing processes.
Below are 10 key advantages that set DRG MOTOR apart from other brands in the industry.


1️⃣ Winding System – The Heart of the Motor, The Source of Power

The real quality of a motor lies in its winding.
The material and workmanship of the winding directly determine the motor’s efficiency, heating, torque stability, and lifespan.

At DRG MOTOR:

  • 100% pure electrolytic copper wire is used (aluminum windings are never used).

  • Windings are impregnated with resin using the VPI (Vacuum Pressure Impregnation) process.

  • This method provides 3 times higher insulation strength compared to traditional dipping systems.

  • Minimum insulation class: Class F (155°C), optional Class H (180°C).

  • Fully automatic CNC-controlled winding machines ensure perfect coil symmetry.

Result:
Lower losses, reduced heating, higher conductivity, longer insulation life, and superior efficiency.


2️⃣ Body Quality – The Foundation of Mechanical Strength

The motor housing is not just a cover; it is the core of vibration control, heat dissipation, and durability.

At DRG MOTOR:

  • All series use cast iron bodies (GG20).

  • Cast iron provides 3 times higher rigidity than aluminum.

  • Internal air channels are designed with CFD analysis to optimize airflow.

  • CNC-machined bearing seats extend bearing life by up to 30%.

  • Electrostatic powder coating provides over 1000 hours of salt spray resistance.

Result:
A quiet, rigid, and durable body structure — ready for heavy industrial conditions.


3️⃣ Energy Efficiency – Power Is Important, But So Is Savings

Energy efficiency is no longer a choice; it’s a necessity.
A motor’s true quality is measured not only by the torque it produces but also by the energy it saves.

At DRG MOTOR:

Efficiency ClassEfficiency Improvement       Average  Energy Saving
IE3 → IE4        +3–5%                Up to 10%
IE4 → IE5        +3–4%                Up to 15%
IE3 → IE5         +8–9%                Up to 20%
  • Uses 0.50 mm low-loss cold-rolled magnetic steel.

  • Rotor–stator air gap machined with micron-level precision.

  • Fully compliant with Ecodesign (EU 2019/1781) regulations.

Result:
Lower energy consumption, reduced operating costs, and environmentally conscious production.


4️⃣ Bearing and Shaft System – The Silent Strength of Motion

The lifespan of a motor is measured by its bearing life.
For this reason, DRG MOTOR uses only first-class bearing systems.

At DRG MOTOR:

  • SKF, NSK, and C&U bearings are standard.

  • Heavy-duty models include regreasable bearing housings.

  • Shafts are CNC ground to 0.01 mm tolerance.

  • Double-lip seals prevent dust, water, and grease leakage.

Result:
Silent operation, minimal maintenance, and bearing life exceeding 40,000 hours.


5️⃣ Cooling and Fan Design – Thermal Balance

The lifespan of a motor is directly proportional to its operating temperature.
A motor that runs cool lasts longer.

At DRG MOTOR:

  • Fans are made of heat-resistant engineering plastics.

  • Fan covers are manufactured from sheet steel.

  • Optimized air channels reduce body temperature by 5–7°C.

  • Noise level: maximum 68 dB(A).

Result:
A cool-running, silent, and long-lasting motor.


6️⃣ Vibration and Noise – The Art of Balance

Rotor balance directly affects both quiet operation and mechanical longevity.

At DRG MOTOR:

  • Rotor balancing: ISO 1940 G 2.5 standard.

  • Noise testing: EN 60034-9 standard.

  • Vibration testing: ISO 10816, ≤1.8 mm/s RMS.

🔊 Noise Levels (dB(A)):

Power Range   Speed  Noise LevelStandard
0.55 – 7.5 kW   1500 rpm   52–57 dB(A)EN 60034-9
11 – 55 kW   1500 rpm      57–62 dB(A)EN 60034-9

Result:
Balanced, vibration-free, and quiet operation — guaranteed mechanical longevity.


7️⃣ Electrical Safety – Power Under Control

The terminal box is the center of electrical safety.

At DRG MOTOR:

  • Brass or copper busbars are used.

  • Terminal boxes have IP55 protection.

  • Cable connections can be reoriented easily.

  • Stainless steel bolts and glands ensure long service life.

Result:
Safe connection, easy installation, and long-term electrical reliability.


8️⃣ Testing Process – Every Motor Is Certified

Quality is not proven by words — it’s proven by testing.

Every DRG MOTOR unit undergoes the following tests before leaving production:

  • Insulation and resistance test (500V Megger)

  • Winding resistance and magnetic loss measurement

  • No-load and full-load performance tests

  • Noise and vibration analysis

  • Efficiency measurement (η, cosφ)

  • Thermal imaging inspection

  • Continuous operation test (S1 – 2 hours)

All data is digitally archived, and each motor receives a unique serial-numbered quality report.

Result:
Every motor is tested, documented, and fully traceable.
