Movement simulation in 3D eddy current transient problem

An algorithm for the simultaneous solving of the equations of the 3D transient electromagnetic field and equations of electric circuits of an electromagnetic device containing moving conducting parts has been elaborated. The A‐T formulation has been applied to the description of 3D eddy current problem. In order to solve the 3D problem, the iterative procedure, in which the 3D task is substituted with a sequence of 2D problems, has been applied. Different procedures for movement modelling have been considered. As an example, the dynamics of a linear induction motor have been investigated.
