Abstract

This paper presents a semi-analytical modeling framework to evaluate the performance of a contactless energy transfer system which consists of multiple primary windings and a linear moving secondary winding. The modeling framework combines steady-state and electromagnetic analysis and is able to deal with different winding configurations, consisting of combinations of non-magnetic materials, iron plates and slotted structures. In this paper the modeling framework is used to compare the geometrical dimensions of the six different winding configurations under the condition of a constant magnetic coupling. The analysis shows that flat and thin primary windings and a flat and wide secondary winding are favorable for a constant magnetic coupling.
