Predicting the behavior of induction machine using motor-CAD and MATLAB packages

Design optimization of induction machines uses computer aided design. These machines are the most suitable choice for various and complex industrial applications and improved efficiency is a key point. Wound rotor induction machines have enjoyed a renascence as the generator in many commercial wind turbines. In this paper, both Motor-CAD and MATLAB packages are employed to predict the electromagnetic behavior of an induction machine during steady-state and transient-state. Finite element analysis of a three-phase, four-pole induction machine is carried by using Motor-CAD and MATLAB in order to complete the comparison. The graphical interfaces of Motor-CAD environment will be utilized to describe the machine geometry, winding harmonics, material properties, and air-gap flux. The predicted results are validated by the experiment. Power losses are calculated for the test machine, and then the results will be explained.
