Abstract :
In this paper, a novel finite element analysis taking account of two-dimensional magnetic properties of non-oriented electrical steel sheet is suggested and applied to performance analysis of a large-scale permanent magnet brushless DC motor. The magnetic properties of non-oriented silicon steel (50A1300) is measured by two-dimensional single sheet tester, and modeled by using extended B-H curve method for non-linear finite element analysis. Through the suggested finite element analysis, the performance such as iron loss and cogging torque is analyzed and compared with numerical results from conventional analysis method.
