What’s after Dowell – Novel Magnetic Field Resolution applied to Analysis of Windings in Electromagnetic Devices

Résumé

Novel approach to accurately compute magneto-harmonic effects in different conductor geometries applied to coils of electromagnetic devices is presented in the paper. Largely used modeling such as Dowell’s or complex permeability approaches show important weakness to reflect 2D phenomena, such as edge effect, air-gap field consideration or modeling partially fulfilled layers of conductors. This new fully analytical modeling offers all the possibility of time consuming FEM simulation and eliminate rising errors of any mesh based method in high frequency range as well as at high dimensional ratios of modeled objects. The way to apply Maxwell equations is mathematically explained to resolve 2D distribution of magnetic potential and field, current density and resulting losses. Unrivaled findings compared to Dowell limitations and FEAnalysis results are clearly shown.
