Abstract :
A quasi-analytical model for the analysis of eddy current distributions and forces in axisymmetric systems with conductors in motion is presented. The model is based on the analytical solution of the vector potential formulation of the Maxwell equations for a sinusoidal steady state regime relating to an axially infinite geometry with conductors moving at a constant velocity. When the conductors move at a constant velocity, the model allows the analysis of axially infinite geometries for every kind of excitation waveform. Finite axial geometries are considered, for iron free systems, superimposing two solutions relating to axially infinite geometries
