Abstract

An algorithm for simultaneously solving the equations describing the 3D magnetic field and equations describing electric circuits of electromagnetic devices has been elaborated. The nonlinearity and anisotropy of the magnetic core have been taken into account. In order to solve the 3D problem a special iterative procedure, in which the 3D task is substituted with a sequence of 2D problems, has been proposed. For the sake of example, the calculations for an a.c. actuator have been made
