Passively Variable Flux PM Motor with Patterned Multi-Layer PCB Coil Technique

This paper proposes a motor with a passive variable Flux function that uses a self-excited wound-field and permanent magnets. The feature of this motor is that the stator and rotor coils are not wound, but are composed of printed circuit board coils that apply multi-layer pattern coil technique. First, the principle and structure of the proposed motor will be explained. Next, performance will be predicted using electromagnetic field simulation, and then the prototype will be revealed. Finally, the preliminary experimental test results will be demonstrated using the actual machine.
