Single Phase 6 pole Generator:
One of the issues with 3d printed generators is magnetic permeability. I used 6 M3x16 bolts to concentrate and make better use of the magnetic flux. One of the benefits of using the bolts (which are arranged radially) is being able to thread them in or out to adjust the air gap.
Non printed components:
- 2x Flanged Ball Bearings 1/2" ID 1/4" ID
- 1x 1/4" diameter D-shaft (1/4" threaded rod can be used)
- 2x 1/4" ID shaft spacers
- 28 AWG Wire
- Heat Shrink
- 12x 10mm x 2mm Diameter Magnets
Print:
- 1x Stator
- 1x LID
- 12x Coil Form
- 1x Rotor
Assembly:
Rotor:
Two magnets fit in each hole, stacked on top of each other. Each pole/hole must alternate N/S/N/S/N/S all the way around the rotor. Press them into place, not too hard or the rotor may crack(depending on the tolerance of your printer). I use glue as well to hold all of the magnets in place. Then I wrap a thin layer of tape around the outside as an extra measure. Inser
