Density-Based Topology Optimization of Conductor Paths for Windings in Slotted Electrical Machines

A density-based topology optimization approach is developed to investigate the distribution of conductive material in a discretized 2D-domain. The initial objective is to maximize the magnetic energy inside regions of interest (stator's teeth), then it is adapted to a multi-objective optimization to provide more control on the design. The developed framework is extended from one stator tooth made of iron, to multiple ones. This paper does not give a final optimized topology for winding in electrical machines but the first steps of a promising design method to achieve it.
