Since 2007 there was adopted a new standard classification for the energy efficiency of electrical motors, in order to gradually limit the impact on the environment. In this paper, we present some studies regarding the environmental savings that can be obtained through the production of more energy efficient machines, barriers in imposing the improved motors, which are met on a worldwide manufacturing market, and a motor power loss analysis in view to establish the methods to reduce them.
