4 Vector Hysteresis Modeling

4.1 INTRODUCTION

For applications where the magnetic field is parallel to the induction, scalar models can be applied with good precision. However, in some situations, a vector relation‐ship between the magnetic field and the magnetic induction is necessary to achieve an accurate evaluation of rotating flux and magnetic losses.

Among several vector models available in the literature, two vector generaliza‐tions of the Jiles‐Atherton (JA) model are considered in this chapter.

4.2 VECTOR MODEL OBTAINED WITH THE SUPERPOSITION OF SCALAR MODELS

Generally, vector hysteresis models present an input vector and an output one. In electromagnetics these vectors may be the magnetic induction, the magnetic field, or the magnetization ...
