Low RPM Axial Flux Generator Cell v3

thingiverse

This small 3-phase AC/DC generator is designed for low energy applications that harness wind or water power. Its stackable design allows users to create a working system with multiple modules, increasing voltage or current as needed. Connecting modules in parallel increases current while series connection boosts voltage. The generator requires specific components including rare earth magnets, copper wire, and thrust bearings, all detailed in the instructions. After building the rotor, coils are wound around it and secured with glue. Once dry, the rotor is assembled onto a threaded rod along with additional magnet brackets if needed. AC voltage is generated by connecting opposite coils together to form three phases. Rectifying these phases using Schottky diodes creates DC output. The generator has been tested with 250-turn coils and produces around 4V AC at 180 RPM, while four combined cells should generate approximately 12.8V DC for powering microcontroller projects.
