Abstract
This is Part II of a paper that sets forth a computationally efficient method to estimate harmonic rotor bar currents in induction motors for accurate loss analysis. The method couples magnetostatic finite element analysis (FEA) and an extended-qd cage circuit model. In Part I, we formulated two subproblems for determining separate components of the induced rotor currents. Part II begins with details regarding the subproblem solution methods. Second, we set forth an FEA-based parameter estimation for the subproblems. Finally, the proposed model is validated by comparing the estimated cage loss and computational effort against a 2-D nonlinear time-stepping FEA.
