OUR ENERGY - YOUR SUCCESS
Electric motors account for a large part of the electricity used. If we look at Sweden, electric motors account for about 65 percent of the electricity used in industry. In the country in total, they account for 40 percent.
To reduce this use of electricity, there are legal requirements regarding the efficiency of electric motors manufactured in the EU, or imported into the EU.
Three-phase, single-speed asynchronous motors are covered by the requirements today. Asynchronous motors are the most common type of motor and account for 90 percent of the electricity consumption of all electric motors in the power range 0.75 - 375 kW.
According to that standard, the energy efficiency classes have the designations IE1, IE2, IE3 and IE4, where IE4 has the highest efficiency.
A revision of the standard was decided by the Ecodesign Committee in 2019. The revision was published on October 1, 2019. The following will apply:
From July 1, 2021
From July 1, 2023
From July 1, 2021
In the exceptions where an IE2 motor is to be used with a frequency inverter, the motor must be equipped with the following sticker:
The requirements do not apply to ships or other means of transport that carry goods or persons, since there must be specially designed engines for this purpose. (If the same mobile conveyor belt is used on ships as well as on land, the rules apply).
Also, the requirements do not apply to repair of motors previously placed on the market, or put into service - unless the repair is so extensive that the product will in practice be brand new.
If the motor is to be further exported for use outside Europe, the requirements do not apply.
Some other requirements apply to water-cooled motors.
In 1998, the EU and the European engine manufacturer organization CEMEP introduced a classification and labeling system for low-voltage AC motors divided into different efficiency classes. This voluntary classification sorted the motors into efficiency classes EFF1, EFF2 and EFF3 where class EFF1 had the highest efficiency.
In 2008, the International Electrotechnical Commission (IEC) introduced the global standard EN 60034-30: 2008 for the classification of three-phase asynchronous motors. According to the new statutory standard, energy efficiency classes now have the designations IE1, IE2 and IE3, where IE3 has the highest efficiency. The standard replaced the previous system.
In 2014, the IEC standard was supplemented with a new standard EN 60034-30-1: 2014.
As electric motors are further developed, the requirements are tightened.
