Summary

Magnetic transmission with 1:4 ratio. There's no contact between input and output ends since reduction ratio is achieved by magnets in the rotors and metal screws in the stator. Both ends have 6.3 mm hexagon shape, which can be used by standard hexagon socket drive. Magnets are press-fit, no glue needed. IMPORTANT: See pictures for magnet polarity in each rotor!
