Abstract :
A method for finite element modelling of transient 3D eddy currents in magnetically nonlinear media is described. The magnetic vector potential A, with or without the electric scalar potential V, is used inside eddy current regions, coupled to magnetic scalar potentials elsewhere. Time transient torque, current and flux values are compared to measurements taken from a rotational test rig
