Specializing 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 these electric motors highly energy-efficient.
Our electric motors are designed to fit and match specific requirements. They can be supplemented with a range of options and accessories or modified with a special design to endure any environment.
⚡ Energy Efficiency Standards
Electric motors account for about 65 percent of the electricity used in industry. To reduce consumption, legal requirements regarding efficiency apply to motors manufactured or exported into the EU. According to standard, energy efficiency classes are designated as IE1, IE2, IE3 and IE4, where IE4 represents the highest efficiency.
Revision of the Standard
The Ecodesign Committee published a revision on October 1, 2019, with the following applications:
From July 1, 2021
- 2, 4, 6 and 8-pole motors (0.75 - 1000 kW) included in class IE3.
- Motors within 0.12 - 0.75 kW must meet IE2.
- IE3 replacement options for IE2 with frequency drives discontinued.
From July 1, 2023
- IE2 applies to Ex eb certified motors with high safety.
- Single phase motors > 0.12 kW covered by IE2 class.
- IE4 applies to 2, 4 and 6-pole motors (75 - 200 kW).
Directive Requirements & Exemptions
Since 2017, all motors 0.75 - 375 kW (2, 4, and 6-pole) must meet IE3 requirements, or IE2 if combined with frequency inverters.
Exemptions Include:
- Non-continuous drive operations (S1/S3 with < 80% cyclicity).
- Motors fully integrated into products (gears, pumps, fans).
- Operation in liquid or explosive atmospheres.
- Extreme temperatures (>60°C or <-30°C) or high altitudes (>4000m).
- Brake motors and specific maritime transport engines.
Frequently Asked Questions
What efficiency classes are available for these motors?
We provide motors ranging from IE1 to IE4 efficiency classes. IE4 represents the highest efficiency level currently available according to international standards.
Can you customize motors for specific industrial needs?
Yes, we have a dedicated design and development team. We can customize single-phase and three-phase motors to meet special customer requirements, including variations in voltage, mounting, and environmental endurance.
What is the standard warranty period for your electric motors?
We offer a comprehensive guarantee of 18 to 24 months on our motor products, ensuring long-term reliability and performance.
What types of standards do your motors comply with?
Our motors comply with multiple international standards including IEC, Epact UL, GOST (Russian standard), and DIN Bsi, as well as NEMA (American) and AEEF (Taiwan type).
What are the typical lead times and shipping methods?
General delivery time is between 15-30 days. We support various shipment methods including sea freight, air flight, express delivery, and land transfer to accommodate global logistics needs.
Are there specific motors designed for explosive atmospheres?
Yes, we offer high-voltage explosion-proof motors. However, please note that certain standard efficiency directives may have different requirements for motors intended for use in explosive atmospheres.
