Human: Magnetic Flux Speed Reducer Demo, 12:1 Speed Reduction. This design leverages 22x 6mm diameter axial magnets and 2x 25.4mm diameter axial magnets, paired with optional 8mm x 3mm ball bearing races for the two rotors, and a 3mm steel or aluminum shaft that supports the bearings. The setup can be modified to use printed axle inserts in place of bearings, pushing them into the flux body or the rotors. This design also employs 12 pieces of approximately 1/4" diameter, roughly 2cm long steel rods to facilitate magnetic flux transfer between the rotors through the flux body. Quarter inch bolts were utilized due to their ability to screw into the flux body and be adjusted for precise alignment. The large magnets significantly overlap the disc, secured in place with electrical tape but not necessary for functionality. This project was printed on a Prusa MK3S and a Monoprice Mini Select III.
