Improvement of Convergence Behavior to Steady-State in Magnetic Field Analysis of Synchronous Motor

Abstract

　The usefulness of a novel simplified time periodic-explicit error correction method for the practical synchronous motors is clarified quantitatively. The method can improve the convergence behavior to the steady state in the analysis of electromagnetic equipment including the DC magnetic field. Furthermore, in order to apply the magnetic field analysis coupled with the electric circuit, the novel method is extended. In addition, the technique, which can improve the convergence to the steady state using the time and spatial periodicity in the analysis of synchronous motors, is proposed, and the usefulness is clarified.
