Magnetic couplings for the motors was a fun way to tackle this without needing to drill anything or use gaskets. I wonder what the efficiency loss due to friction is in comparison to a traditional drive shaft through a gasket.
- convolvatron 5y agoseems like you could mount the magnets on both sides on bearings (whose housing would either have to be glued or use even more magnets to be fixed to the surface)
- sliken 5y agoSure, but not sure the rolling friction of bearing on plastic and bearing on bearing race would be less than the current magnet sliding on teflon. It's also a fair bit of complexity, weight, and expense. Not sure how long bearings would last in the relatively corrosive environment of chlorinated water.
