In the present work, a mathematical modeling of the design of induction motors is developed that assures the best utilization of active materials. In this model the choice of the optimal transverse geometry and of the optimal value of air gap induction are taken into account.
The air-gap interface coupling method is developed to simulate the rotor movement with time-stepping finite element (TSFE) method for the computation of transient operation of induction motors. The use of Fourier decomposition of magnetic vector potential on the coupling interface leads to the consideration of only the first or just significant space harmonics in FE computation. In this way, the study...
