“…Thus raising the harmonization level performance standards MEPS (Minimum Energy Performance Standard). The standard defines the international efficiency classes (IE code) and requirements corresponding, provides the test conditions and performance measurement methods described in IEC 60034-2-1 2007, but does not establish motors minimum performance level (MEPS); this depends on the different legislation force countries and governmental objectives about energy saving and ecological sustainability [4][5].…”

In the final decade of the last century, there was enormous intellectual and engineering activity surrounding the recently invented induction motor, especially their efficiency increasing. The interest in improving the efficiency of electric motors stems from the fact that they represent 60 to 70% of the total industrial and commercial load. A knowledge the motors operating efficiency in an industrial plant is necessary, when deciding whether standard motors should be advantageously replaced with more efficient motors. A new approach is presented for analysis and design of closed rotor slot induction motors in this paper. The main idea is illustrated as follows: first based the computed machine parameters and motor geometry optimization will be carried out. Then, to validate the conceived machines, dynamical performance analysis will be achieved by MATLAB environment. Finally using finite element electromagnetic field analysis, the comparison results will be discussed and commented.
