Abstract

When mathematical models of electromagnetic devices are described by ordinary differential equations, then the magnetization curves of their cores are often expressed with a help of nonlinear coefficients. Sometimes such an approach is considered questionable, and therefore, the purpose of this chapter is to prove its admissibility. 

Keywords: Choke, Induction motor, Magnetization curve, Mathematical model, Nonlinearity, Ordinary differential equations, Transformer.
