ABSTRACT Modeling of electromagnetic problems in electrical systems, machines and devices are a practical subject and importance for researchers and manufactures, specially for the problem getting a line winding structure. The electromagnetic problems are almost presented the set of Maxwell equations and their behaviors. These are partial differential equations written as differential and integral, described distributions of electromagnetic fields in the space and variation in time. In order to analyze this problem, in this paper, a partial element equivalent circuit is applied to compute distributions of electromagnetic fields and induction currents in turn windings, where occuring some difficuilties as applying directly by a finite element method or a finite differential method, because of the big degree of freedoms, leading to a big size of matric and spending a lot of time for computation. The obtained results will be compared with the simulation results of commercial software. Keywords: Electromagnetics, Induction current, finite element method, partial element equivalent circuit. |
