Sub-Optimization of a claw-pole structure according to material properties of soft magnetic materials

The focus of this paper is on the development of a single phase PM machine with wave-windings where the design variables are the winding layout and design of a soft magnetic powder core for a stator. A number of BH curves are synthesised in order to characterise some of the existing powder cores and to study the influence of magnetic permeability on starting torque and mean driving torque. The goal of the wave-winding design is to increase the material utilisation factor and minimize the resistive power losses in the winding of a radial-to-transversal flux machine with an iron powder core. The outcomes of this paper is a 3D FE magnetic analysis of a number of suggested stator layouts supported with a rapid prototype with a dummy coil
