How to Make Your Company More Green
The second phase of regulatory changes in European regulations on the eco-design of electric motors took effect on July 1, 2023.
New motors intended for the European market with a rated power output between 75 kW and 200 kW will have to comply with IE4 class.
According to the new regulations, single-phase motors with a power output of 0.12kW or higher will also have to comply with IE2 class as a minimum.
By taking steps now to upgrade motors and drives, companies can thus not only make their operations more sustainable, in advance of the new obligations coming into effect, but at the same time reap the long-term economic savings resulting from increased efficiency.
Indeed, energy represents a substantial portion of the total cost of a motor over its entire operating life.
It is also estimated that electric motors account for about 45 percent of global energy consumption, with 8 billion units being used in Europe alone.

Advantages of Using High Efficiency Electric Motors
Reduced Energy Consumption
In 6 months electricity consumption is reduced from 10% to 40% with respect to standard motors. Purchase costs can be compensated.
Low Energy Waste
A more advanced design enable lower energy losses, by guaranteeing best performances. Excellent cooling system.
Reduced CO2 Emissions
The Premium Efficiency Electric Motors keep high efficiency levels, by reducing CO2 emissions and safeguarding the environment.
Comparison Table
Efficiency levels based on IEC 60034-30-1
The table shows a comparison between IE2 and IE3 efficiency levels, according to the standards IEC 60034-30, and the new W22 Super Premium Efficiency line.
The investment for the replacement of installed motors with W22 Super Premium Efficiency motors will be repaid in a short period of time.
The energy savings will be even more considerable, if the old motor had been subject to repairs during his lifetime, since each repair can reduce performance by up to 1% of efficiency.
Thanks to innovative design, there is 20% to 40% less downtime and extended motor lifetime, even in strenuous operating conditions.
Calculate Your Savings
As electric motors usually run for thousands of hours every year, replacing them with more efficient motors entails relevant economic advantages and pays the initial investment back in short time, providing energy savings and underlining the reliability of the plant.
Therefore, it is necessary to adjust old industrial sites to the latest energy efficiency solutions to obtain low consumption and reduced environmental impact.
According to DIN EN 50347 standard, it is possible to replace a IE1 or IE2 motor with a IE3 or IE4 one, being sure that such investment will provide a constant payback.
