Proceedings of the Institute of Electrodynamics of the National Academy of Sciences of Ukraine| Summary: | The methodology of analysis of electromagnetic processes in an inductor with a U-shaped ferromagnetic core is presented. The inductor is designed for contactless excitation magnetic field pulses and high density currents in nonmagnetic metal plates. A two-dimensional electromagnetic field simulation methodology takes into account the thickness of the metal plate; the air gap between the ferromagnetic core and the nonmagnetic metal plate; detailed dimensions of the inductor; dependence of active resistance on pulse duration; inductance of the frontal parts of the winding; additional resistance from eddy currents in the plate under the frontal parts of inductor. The calculation of the parameters of the inductor is done in this paper. The parameters of the inductor calculated according to the presented methodology are compared with the parameters calculated in the three-dimensional model by the finite element method. It is shown how the parameters of the inductor change when the magnetic circuit is saturated. References 5, figures 3. |
