The paper presents the circuit network models for magnetic field calculation in electrical machines. Permeance and reluctance networks are considered. Both networks can be formed by means of finite element method. In the case of permeance network the interpolation functions of edge element are applied. Reluctance networks are formed using the interpolation functions of facet elements. The loop equations of reluctance network represent the equations of edge element method for magnetic vector potential. However, the nodal equations of permeance network are equivalent to the equations of finite element method using nodal elements and scalar potential. Attention is paid to the network representation of field sources and to the procedures of flux linkage calculation using branch fluxes in permeance network and loop fluxes in reluctance network. The methods of magnetomotive forces formulation are discussed. Selected examples of these forces calculation are given.
