Design of a Multi-layer PCB Coreless Axial Flux Magnetic Resonant Motor

This paper proposes a novel multi-layer coreless printed circuit board (PCB) axial flux magnetic resonant motor (PAFMRM). The PAFMRM transfers electrical energy between the stator and rotor through magnetic resonance coupling, initiating electromechanical energy conversion. The stator and rotor coils of the motor are traced on 5-layers PCB board. The overall design is a 10-layer compact stacked PCB machine. The coils that constitute the windings of the motor are traced on the copper conducting layers of the PCB. A non-conducting substrate layer separates parallel conducting layers. The stator and rotor side coils are divided into a two-phase winding system. The characteristics of the motor are studied through a complete finite element analysis in the paper. In addition, the concept of magnetic resonance on a PCB is verified.
