Motor /Generator Stator Casting Mold (7.75" diameter with 12 slots)

thingiverse

This is an experimental casting mold process designed specifically for advanced tinkerers. The outer diameter measures 7.75 inches, while the inner diameter is a precise 4.0625 inches and the depth stands at 2.125 inches. This setup represents a viable alternative to traditional silicone steel or metglas/ceramic type stators for DIY enthusiasts. A wide range of magnet and wiring configurations can be explored, allowing users to design their own motor/generator housing, bearing holders, and wire schemes/circuits. Telsagenx offers basic circuits for pulse motors/energizers and energy recovery systems for those looking to push the boundaries of this project.

A video explaining steel shot preparation and crediting the innovators behind coated steel shot can be found at https://www.youtube.com/watch?v=kpHEyzvc4dY. Please note that this project carries inherent risks, and users are advised to proceed with caution. The final product has not been thoroughly tested for heat dissipation, load testing, or reliability. Sourced materials have been used outside of their recommended specifications, yielding results specific to my own experiment. For those interested in building a generator or pulse motor, an optional rotor file is available. This design features magnets measuring 2 inches by 1/2 inch by 1/8 inch, with a shaft diameter of 3/4 inch and set screw size of 1/8 inch. Video instructions for this project can be found at https://www.youtube.com/watch?v=LzC5SP4e_uA, https://www.youtube.com/watch?v=aPIIT2ObSvc, and https://www.youtube.com/watch?v=3uz2U-aGob4. On July 8, 2017, I added sample motor end/bearing holders to the project files. This design accommodates 3/4 inch by 1 5/8 inch by 7/16 inch bearings, featuring inner bolts of 6-32 x 3/4 inch and outer holes for 1/8 inch threaded rod connections. There is approximately one inch of clearance on both sides of the stator for wire to protrude. On August 11, 2017, I introduced new bearing legs that secure the stator in place using 1/4 inch x 5 inch bolts. Additionally, a reduced 9-piece rotor design was added for users with smaller printer beds, requiring M4-.70 x 60 bolts (four of them). Stator end caps have also been designed to keep wires in place, simply attach them using Gorilla glue.
