The new EU directives require the use of variable speed drives in the operation of the new generation motors, said George Stoica, Product Manager, Eaton Romania, at the conference “Digitalization and Energy Efficiency – Cluj- Napoca”, organized by Energynomics.

Eaton, a global company operating on all continents, focuses in Romania, outside production facilities, on energy management, said George Stoica.

“We can provide components and solutions for everything in the primary energy chains – from production to consumer, including the area of industrial automation and the efficiency of these transportation, supply, automation or electrical drives processes. In Romania, we are present through the local office in Bucharest, as well as our local offices – Cluj-Napoca, Timisoara, Baia Mare, Iasi, Constanta, Craiova and Brasov. From a production point of view, we have three plants, one near Arad and two more in the Maramures county,” he said.

Energy efficiency through variable speed drives involves two major lines of action, regulated by European Directives. The ErP Directive of 2009 promotes the use of variable speed drives by two regulations. ”Energy efficiency engines 3 (IE3) should be used.”

Since 2015, there has been an exception, IE2 motors with variable speed drives (0,75-7.5kW) or IE3 could be used. Since 2017, the power range has been extended to 375 kW, but it is usually inefficient to operate an electric motor directly from the grid, so a variable speed drive is needed to get speed control and eliminate losses, he said, then giving details and technical explanations.

The conference “Digitalization and Energy Efficiency – Cluj-Napoca” was organized by Energynomics, with the support of our partners ABB, Cargus, Claritech, CREESC, Eaton, Enel X Romania, EnergoBit, Kawasaki Gas Turbines Europe, Photomate, Renovatio, Sensible, Wiren.

More than 220 people registered on the MyConnector platform to participate in the dialogue.
