Abstract

This paper presents a original method for open magnetic cores modelling. It iscalled the distributed point source method. It is based on a spatial distribution of pointsources located on the core surfaces emitting the magnetic flux, called the active surfaces.Compared to Finite Elements methods, the DSPM method requires only the meshing of theseactive surfaces, which considerably reduces the solving process time. In this paper, the DSPM method is applied on a magnetic cylindrical core, placed in free space.
