Abstract
Standard Galerkin finite element method (SGFEM) cannot solve eddy-current problems with dominated motional terms accurately and effectively. A numerical method for analyzing eddy-current magnetic field in high-speed rotating solid conductors using operator splitting finite element method (OSFEM) is presented. An artificial example and a benchmark transient eddy-current field problem, the problems 30A and 30B in testing electromagnetic analysis methods (TEAM) workshop, are used to test the accuracy and performance of the method. It is demonstrated that the numerical solution using the proposed method is nonoscillatory even for convection dominated cases. Besides, the calculated torque values are more accurate using the proposed OSFEM when compared with those obtained using SGFEM. It is concluded that the OSFEM can solve eddy-current problems with high-speed rotating conductors efficiently and accurately.
