Abstract

A bout magnetic properties testing method of magnetic steel strip used as a core of electrical machinery and apparatus, a standardized Epstein testing method, a single sheet tester (SST) method and the being two-dimensional magnetic measurement method which now investigation of measuring device was pushed forward were described. Modeling of magnetic properties of electrical steel necessary for magnetic field analysis of electrical machinery and apparatus was described, and analysis example of core loss characteristic of three-phase induction motor was shown.
