The paper discusses the method of solving the finite element (FE) equations that describe the magnetic field distribution for scalar and vector potential formulations. The 3D field problems have been analyzed. The nodal FEs for a scalar potential and the edge elements (EE) for a vector potential are considered. The FE equations have been described using the language of circuit theory. For selected...
The scalar and vector potential formulations for electromagnetic fields calculation using finite element (FE) methods are discussed. Attention is paid to the application of these formulations in the 3D analysis of magnetic field in electrical machines. The nodal FEs for scalar potentials and the edge FEs for vector potentials are considered. The equivalent magnetic network models related to both formulations...
The paper presents network models that are used in the analysis and design of electromagnetic actuators. The attention is focused on the magnetic networks. Both permeance and reluctance networks are analyzed. The presented network models are formed using the finite element methods. The interpolating functions of edge and facet finite element are applied in the calculations of branch permeances and...
