3 Phase AC Generator

The spinning magnet creates 3 sine wave voltages in the coils which is studied with SEELab3

Photo of the setup designed with FreeCAD and printed on a BambuLabs P1S. The magnet holder wasn’t symmetric enough, so I redesigned it later.

The setup gave 3 clean sine waves with almost 120 degree phase difference between each. The small error can be attributed to mounting the coils in their sockets which have some tolerance.
