Distribution of two-dimensional magnetic properties in three-phase induction motor model core

Abstract

This paper presents the result for the local magnetic properties in a three-phase induction motor model core. The relationship between the magnetic field strength vector H and the magnetic flux density vector B, is obtained through measurements with a special sensor, which utilizes the H-coil method and the double needle method. As a result, the relationship between the H-vector and the B-vector is made clear, and it is shown that the local properties in an actual core are vectorial in nature.
