Abstract

One of the difficulties of the three-dimensional (3-D) eddy current finite element methods is to solve large finite element equations economically. In this paper a 3-D eddy-current finite element model using a four component formulation of complex variables to study skewed rotor induction motors is described. An iterative process among the four specific components during the solution of large algebraic equations is presented. The proposed method overcomes the non-convergence problems when the ICCG method or the shifting ICCG method is used directly. The algorithm also requires much less computer storage compared with the Gaussian elimination method.
