Abstract

As it is known, the induction motors with squirrel cage rotor are classified according to IEC 60034-30:2008 in three efficiency classes: a. Standard Efficiency IE1; b. High Efficiency IE2; c. Premium Efficiency IE3. According to the ecodesign requirements, since 01.01.2015 respectively 01.01.2017 motors shall not be less efficient than IE3 efficiency level. The motor manufacturers are obliged to comply with this requirement, developing the IE3 variant. This paper refers to the mode of execution of these motors, to the applied technical solutions and to the obtained results.
