Influence of Magnetic Saturation in Inhomogeneous Magnetic Field

Abstract

The field distribution of an inhomogeneous magnetic field in the conical pole gap is calculated considering the influence of magnetic saturation of pole material. Magnetic fields corresponding to the ideal n-values of -1.5 and -2 are calculated for various different field strengths. The results show that the distortion due to the magnetic saturation is very serious in the strong magnetic field above 15 kG for pure iron and above 20 kG for vanadium permendur. The variations of n₁ and n₂ with increasing B are also shown.
