Improvement of Convergence Characteristics for Steady-State Analysis of Motors With Simplified Singularity Decomposition-Explicit Error Correction Method*

In order to improve the convergence for steady-state analysis, the simplified singularity decomposition-explicit error correction (SD-EEC) method is developed. This paper proposes techniques to apply the simplified SD-EEC method to an interior permanent magnet (IPM) motor and to an induction motor. The usefulness of the techniques is verified through the applications to an interior permanent magnet (IPM) motor and an induction motor.
