DRG Motor IE4 Electric Motor Series

Contact: +90 (542) 666 11 11

The DRG Motor IE4 Electric Motor Series combines maximum efficiency, reduced energy consumption, and long-term durability to meet the needs of modern industrial operations. IE4 motors are among the highest efficiency classes in global standards, delivering extremely low electrical losses and substantial annual energy savings for facilities with continuously operating equipment. DRG Motor’s engineering approach incorporates high-permeability magnetic cores, optimized rotor geometry, high-conductivity copper windings, and enhanced cooling channels, ensuring maximum performance even under the toughest operational conditions.

Energy efficiency is the defining characteristic of IE4 motors. With a 3–5% higher efficiency compared to IE3 motors, the IE4 series significantly reduces energy costs in applications such as pumps, compressors, conveyors, crushing systems, and fan units. The motor requires less current under the same load, produces less heat, and generates more stable torque thanks to its improved magnetic structure. These improvements lead to lower operational losses, longer system life, and increased efficiency in energy-intensive environments.

The mechanical structure of the DRG Motor IE4 series is engineered for durability. The GG20 cast-iron body absorbs vibration and prevents resonance in heavy-duty applications. Each rotor is dynamically balanced to ISO 10816 vibration standards to ensure smooth operation. High-temperature SKF or C&U bearings provide long service life, especially in continuous run (S1 duty) applications. With its IP55 protection rating, the motor is resistant to dust, moisture, and harsh industrial conditions.

Thermal performance is another major strength of the DRG Motor IE4 series. The F-Class insulation system withstands high temperatures, while vacuum-impregnated windings maintain stability under sudden load changes. The optimized cooling fins increase airflow and reduce overall temperature rise, helping extend bearing and winding lifespan. Reduced thermal stress directly contributes to long-term operational reliability.

The motor’s maintenance-friendly construction enhances its practicality in the field. The enlarged terminal box allows easier wiring, while mounting configurations such as B3, B5, and B35 make the motor compatible with a wide range of industrial machinery. Full IEC dimensional compatibility ensures seamless replacement of older motors and simplifies installation processes.

Combining high energy efficiency, low operating costs, long service life, and robust mechanical strength, the DRG Motor IE4 Electric Motor Series is an ideal solution for companies aiming to meet the next generation of energy performance standards. As energy prices continue to rise globally, IE4 motors not only provide substantial cost savings but also contribute to environmental sustainability and efficient industrial production.
