An approach to model skewed induction motors using multislice two-dimensional eddy-current finite-element analysis is presented. Using the transmission line modeling method to model nonlinear material properties, domain decomposition may be applied to the solution of combined field and circuit equations. As a result, the simulation may be parallelized efficiently. Comparisons of the proposed parallel technique with serial simulations and test results are presented, indicating that the proposed technique accurately predicts motor performance. Timing data clearly show that the technique scales well with increasing number of processors.
