Domel is showcasing its ultra-high efficiency EC motors at the ISH trade fair in Frankfurt under the slogan "Solutions for a Sustainable Future".
Domel has now been developing and producing energy efficient EC motors, which rank among the best in the world in terms of efficiency, for thirty years. According to the International Energy Agency, electric motors and drive assemblies consume around half of all the electricity produced on Earth, which is why increasing their efficiency has great potential for reducing greenhouse gas emissions and helping with environmental protection.
One of the company’s market segments is electronically commutated (EC) motors. Due to their reduced electric power consumption, their greater efficiency is reflected in fewer greenhouse gas emissions and a lower environmental impact. EC drive systems intended for use in heating, ventilation and air conditioning (HVAC) in particular rank among the top five consumers of electricity. Due to their continuous, 24/7 operation, energy consumption is even more important in the applications in which such motors are used.
We estimate that the use of our IE5 efficiency-rated HVAC motors sold during the last eight years (2015–2022) saved more than 400 GWh of electricity in 2022 compared to the best-selling traditional asynchronous motors. This saving of 400 GWh of electricity can be translated into 92,700 tonnes fewer CO2 emissions, which is equal to the emissions generated by 19,900 cars in one year.
When developing our HVAC motors, a great deal of emphasis is placed on the optimal use of materials, state-of-the-art technology, a high level of efficiency and long service life. The motors do not require maintenance, as they do not contain mechanical parts subject to wear, with the exception of the bearings.
 The calculation was made based on the Rules on the Methods for Determining Energy Savings: http://www.pisrs.si/Pis.web/pregledPredpisa?id=PRAV14191. The EU electricity emission factor for 2020 (0.23 kg of CO2/kWh) was used for the calculation of savings of CO2 emissions.

 The CO2 emissions equivalent was calculated using the greenhouse gas equivalencies calculator on the website: https://www.epa.gov/energy/greenhouse-gas-equivalencies-calculator.
