Magnet Stator for a Mini Windmill Style Generator

thingiverse

This thing is specifically designed as a magnet stator for windmill style generators, engineered to work perfectly with 1/2" x 1/4" round magnets. The shaft hole is precisely 1/4", extending all the way through the entire piece at a length of 1.55". From base to end, the stem measures 1.25", and the diameter of the circle is an impressive 3.5". To ensure a solid connection, I lightly sand the shaft before adding a small amount of Gorilla Glue near the end of the shaft, then slide on the stator. After allowing it to sit for 24 hours to cure, you may need to run a 1/4" drill bit through the piece to guarantee a smooth fit. This thing can be easily scaled up by 200% to accommodate 1/2" shafts and 1" magnets.
