Abstract
Electromagnetic field problems arising in electrical machinery and devices are in general truly three dimensional in nature. In many devices natural excitation is the voltage excitation, for example: relays and electrical motor. Several research papers have been published on the subject of three dimensional field solutions. Many different formulations of the 3D electromagnetic problems are possible. They involve differential or integral formulations in terms of scalar or vector unknowns. The aim of this paper is to present a method capable of solving general 3D eddy currents with voltage excitation in nonlinear magnetic field using the A, A‐V formulation. The method of the finite difference equations formulation based on minimising of the energy functional has been given.
