Electric motors used in industrial facilities account for a significant portion of total energy consumption. Therefore, motor energy efficiency is crucial for reducing operational costs and minimizing environmental impact. At DRG Motor, we are fully aware of this responsibility and offer high-efficiency motor solutions to help businesses achieve sustainable operations.

How Are Efficiency Classes Determined?

Electric motor efficiency classes are defined by the International Electrotechnical Commission (IEC) under the IEC 60034-30-1 standard. This classification applies to three-phase asynchronous motors ranging from 0.75 kW to 375 kW and indicates how effectively the motor converts electrical energy into mechanical power.

IEC Efficiency Classes

According to IEC standards, motors are categorized as follows:

  • IE1 – Standard Efficiency: The lowest efficiency level. No longer recommended for new installations.

  • IE2 – High Efficiency: Provides basic energy savings. Considered the minimum acceptable standard in many regions.

  • IE3 – Premium Efficiency: Now mandatory in regions such as the European Union and Turkey for new installations.

  • IE4 – Super Premium Efficiency: Delivers lower energy consumption, longer lifespan, and reduced operational costs.

  • IE5 – Ultra Premium Efficiency: Represents the latest advancements in motor technology. Not yet widespread, but viewed as the future standard.

Why Is Efficiency Class Important?

When selecting a motor, it's essential to consider not just the purchase cost but the total cost of ownership (TCO). A motor with a higher efficiency class may have a higher upfront price but will quickly pay for itself through lower energy consumption.

Moreover, using high-efficiency motors helps reduce carbon emissions and supports environmentally friendly manufacturing — benefiting not just businesses, but also society and the planet as a whole.
