Product Description

We specialize in high-quality energy-efficient electric motors. The combination of the best available materials, high-quality sheet metal, and the right amount of copper in the rotor/stator makes our electric motors highly energy-efficient.

We design our electric motors to fit and match specific requirements. These motors can be supplemented with a range of options and accessories or modified with special designs to endure any environment.

Electric motors account for a large part of industrial electricity use. To reduce consumption, there are legal requirements regarding the efficiency of electric motors manufactured or exported into the EU. Three-phase, single-speed asynchronous motors are the most common, accounting for 90 percent of the electricity consumption in the power range of 0.75 - 375 kW.

Standard Revision and Efficiency Classes

According to international standards, energy efficiency classes are designated as IE1, IE2, IE3, and IE4, where IE4 represents the highest efficiency level.

From July 1, 2021: 2-, 4-, 6- and 8-pole motors from 0.75 - 1000 kW are included in efficiency class IE3. Motors within the range 0.12 - 0.75 kW must meet efficiency class IE2.

From July 1, 2023: For 2-, 4-, 6- and 8-pole motors from 0.12 - 1000 kW, efficiency class IE2 also applies to Ex eb certified motors. Higher efficiency class IE4 applies to 2, 4 and 6-pole motors between 75 - 200 kW.

Exemptions from the Directive

  • Operation other than S1 (continuous drive) or S3 (intermittent drive) with a nominal cyclicity factor of 80 percent or lower.
  • Electric motors made for use in liquid or fully integrated into products (e.g., gears, pumps, fans).
  • Brake motors and motors for altitudes exceeding 4,000 meters.
  • Operating in extreme temperatures (above 60°C or below -30°C).
  • Motors intended exclusively for export outside Europe.

Frequently Asked Questions

What are the different energy efficiency classes for electric motors?
Energy efficiency is categorized into IE1 (Standard), IE2 (High), IE3 (Premium), and IE4 (Super Premium). IE4 offers the highest level of energy savings.
Which motors are currently required to meet the IE3 standard?
Since July 2021, 2-, 4-, 6-, and 8-pole motors with a power output between 0.75 kW and 1000 kW must comply with the IE3 efficiency class for use within the EU.
Are there any environmental conditions that exempt a motor from these regulations?
Yes, motors designed for extreme altitudes (above 4000m), extreme temperatures (above 60°C or below -30°C), or those fully integrated into other machines like pumps or compressors are often exempt.
What materials are used to ensure the high efficiency of your motors?
Our motors utilize high-quality sheet metal and optimized copper content in the rotor and stator to minimize energy loss and maximize performance.
Can these motors be used with frequency inverters?
Yes, many of our motors are compatible with frequency inverters for speed control, and as of 2021, specific IE2 efficiency standards also apply to the inverters themselves.
Do you offer customization for different international standards?
Yes, we provide motors compliant with various standards including American NEMA, Russian GOST, and international IEC standards.
