In industry, systems driven by electric motors consume about 70 percent of all electricity consumed. Therefore, they are given special attention in the Ecodesign Directive, which implements the concept of environmentally friendly product design in the EU. Electric motors have actually become much more economical in recent years. Nord Drivesystems supports its customers with new technologies to unlock further savings potential.
Eco-design policy implementing: At energy saving the entire drive system must always be included, including the electric motor, transmission and drive electronics. The potential here is usually around 30-60 percent. However, this post is specifically for that purpose The possibilities of electric motors in relation to According to official OECD data, from 2000 to 2017 industry achieved the highest share of energy savings achieved through improved energy efficiency at 51 percent. The largest share is for process heat production and electricity use in drives.
Electric motors and the Ecodesign Directive
Regarding the Ecodesign Directive, electric motors are the most relevant product group, especially for energy consumption in industry, as electric motor-driven systems consume about 70 percent of the electricity used in industry. It is estimated that in 2015, electric motors converted about 1,400 terawatt hours of electricity into mechanical energy and heat. This is why there are regulations for continuous duty electric motors almost all over the world. Energy efficiency regulation saves resources but also increases profitability. Even electric motors that operate continuously in one shift and that are supplied according to today’s regulations (eg IE3) quickly pay back the additional costs compared to the investment in IE1 motors that were common in the past.
When the first wave of optimization started
Manufacturers of asynchronous motors had to take the first significant step towards increasing efficiency in preparation for the 2011 At that time, with the entry into force of Directive 640/2009 (valid until June 30, 2021), the use of IE2 motors for continuous operation became mandatory…
