Abstract
The paper deals with a coupled field‐circuit simulation of transient and dynamic states in a non‐linear axisymmetrical electromagnetic device. The mathematical model of the dynamic phenomena includes: an equation of transient electromagnetic field in a non‐linear conducting and moving medium, equations of the converter electric circuits and the equation of mechanical motion. The numerical implementation of the algorithm is based on the finite element method. The Crank‐Nicholson scheme for time discretization has been applied. In order to include nonlinearity, the Newton‐Raphson process has been adopted. The influence of the saturation effect on the dynamic characteristics of the device has been investigated.
