Abstract

The paper describes a combination of methods for the three dimensional magnetic field simulation of rotating machines using the finite element method. The modelling takes into account both the external circuit and movement of the rotor. The electric coils are represented in a mesh-independent fashion by the line current model. The equations from a nodal analysis of the electric circuit are solved simultaneously with the finite element equation system at each time step. The movement is treated using a finite element connection between the two independent stator and rotor meshes
