Numerical Design Compatibility of Induction Motor With Respect to Voltage and Current Sources

In this paper, the optimal driving point of induction motor is selected for guaranteeing torque production, which is fed by d-q current combination, and numerical design compatibility employing current source FEM is verified via comparison with the one employing voltage source method. In particular, vector control considering voltage and current constraints has been implemented numerically with FEM when selecting the optimal driving point. Moreover, comparative analysis is performed for the design results, such as magnetic saturation and iron loss, according to driving points selected in designing procedure. With the identified results, the design compatibility of FEM engaged with the current source is validated with comparison of the one obtained by FEM and equivalent circuit method engaged with the voltage source.
