Enhancing PCB Motor Performance through Phase Resistance Reduction in Slotted PCB Motors with Ferrite Core

In the highly competitive automotive industry, minimizing production costs while maintaining product performance is a critical design objective, particularly for mass-produced devices. A recently introduced cost-effective motor concept tailored to such demands is a three-phase axial flux permanent magnet motor topology that employs a printed circuit board (PCB) instead of a conventional winding with a ferrite core, thereby reducing the drive’s complexity, cost, and component count. The main focus of this study is implementing different strategies to minimize the phase resistance of PCB motors. A comparative analysis between the existing PCB design for a PCB motor with a ferrite core and the enhanced version of the PCB with reduced resistance has been done. The validation of simulation outcomes has been reinforced through precise experimental measurements, thereby enhancing the reliability of the conclusions.
