Originální abstrakt

This paper compares four different approaches to modeling of magnetic circuit in the ANSYS software. The approaches differ in various inputs of magnetic field source and varying levels of axial symmetry. The accuracy and the solution time were the main evaluation criteria. The analysis was performed on a simple magnetic circuit. The analysis results were compared with measurements on experimental device that was made for this purpose. The results show that planar solution in ANSYS Classic is the fastest and the highly accurate approach. The problem solution such as 3D axisymmetric task with the definition of magnetic field source with the stranded type is the most accurate, but more time-consuming.

Český abstrakt

Tento článek porovnává 4 různé přístupy k modelování magnetického obvodu v SW Ansys. Přístupy se liší v rozdílných vstupech magnetického pole a různou úrovní axiální symetrie. Hlavními hodnotícími kritérii byla přesnost a doba řešení. Analýza byla provedena na jednoduchém magnetickém obvodu. Výsledky analýzy byly porovnány s měřením na experimentálním zařízení, které bylo pro tento účel vyrobeno. Výsledky ukazují, že rovinné řešení v SW Ansys Classic je nejrychlejší přístup s vysokou přesností. Nejvíce přesné, ale časově náročnější řešení je řešení úlohy pomocí 3D axisymetrie s definicí zdroje magnetického pole pomocí typu Stranded.
