Abstract

This paper describes the torque production capabilities of planar magnetics windings and presents an automated procedure for coils conductors’ arrangement. The procedure has been applied on an ironless axial flux slotless permanent magnet machines having planar magnetic stator windings, such as printed circuit board (PCB) coils. The proposed method is driven by optimization techniques whose goal is to find a proper arrangement of PCB traces, which make up stator windings, in order to find some trade-off solutions, optimal respect to the maximization of average torque and the minimization of torque ripple. A time-efficient numerical model has been developed to reduce computational load and thus make the optimization based design attractive.
