Vector magnetic property of electrical steel sheet and its influence on distributions of magnetic field and iron loss for electrical machines

摘要

Purpose - The purpose of this paper is to present the vector magnetic properties of the electrical steel sheet and investigate its influences on the magnetic field and iron loss distributions for the electrical machines. Design/methodology/approach - The vector magnetic property of the electrical steel sheet is measured by using a two-dimensional single sheet tester and modelled through an E&S vector hysteresis model to be applied to finite element analysis. Findings - The magnetic field and iron loss distributions are calculated by finite element analysis combined with the E&S vector hysteresis model for the three-phase transformer and induction motor models. Originality/value - The influences of the vector magnetic property on the electrical machines are verified by comparing with the numerical results from a scalar magnetic property.
