Mass and cost figures for spatial axial three-phase electromagnetic systems with circular and hexagonal forming contours of twisted magnetic core rods

Abstract

For a spatial three-phase axial electromagnetic system with double-contour phase elements of the twisted butt-end magnetic core, analytical dependences for optimal geometrical relations determination over minimum active part weight and cost criteria are obtained, advantages of the core elements hexagonal cross-section configuration shown.
