Magnetic characteristic analysis and measurement of three-phase generator utilizing grain-oriented silicon steel sheets

Abstract

This paper presents results of magnetic characteristic ana lysis of a three-phase generator utilizing grain-oriented silicon steel sheets. In the analysis, the finite element met hod taking account of the two-dimensional magnetic properties is used to make clear rotational iron loss distributions. In this pa per, the knowledge obtained in the numerical simulations by means of the integration-type dynamic E&S modeling is reported. Also, the measurement results of a prototype generator designed with the magnetic characteristic analysis are shown.
