Magnetic Circuit Regions: Magnetizing Reactance Values in Terms of the Curvature

Abstract

In Chap. 5, magnetizing reactance values of stator and rotor magnetic circuit regions were obtained on the basis of their cylindrical models. In practice, expressions for magnetizing reactance values determined via the planar magnetic circuit model are preferred. When using the planar model, magnetizing reactance values of the magnetic circuit regions are described by the hyperbolic function. In this case, we have sufficient simple and visual expressions that simplify the analysis process. Stator and rotor magnetizing reactance values obtained in Chap. 5 on the basis of the cylindrical magnetic circuit models are represented in this chapter through corresponding planar model expressions. Expressions of magnetizing reactance values obtained in this way take into account the curvature of the surfaces of the magnetic circuit regions. As a result, simpler expressions for magnetizing reactance values of magnetic circuit regions are derived. This provision is realized in this chapter.
