This paper proposes a multi-objective design optimization approach for printed circuit board (PCB) stator coreless axial flux permanent magnet (AFPM) machines based on detailed PCB layout. The process begins with the machine envelope an evolutionary algorithm and 3D finite element analysis (FEA) models continues of aimed at minimizing eddy circulating current losses. employs different open loss mitigation techniques while taking into account manufacturing limitations standards. is explained through integral horsepower AFPM machine, which was prototyped tested. experimental results indicate negligible losses 96% efficiency speed 2,100rpm output torque 19Nm, thereby validating efficacy proposed approach.
