Louis Luu Posted April 24, 2023 Author Share Posted April 24, 2023 Rotor is done. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted April 25, 2023 Author Share Posted April 25, 2023 Housing for the stem. I designed it so the fan can be hung upside down. The commutator will be customized with holes for the wires to run from the shaft. Draft. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted April 26, 2023 Author Share Posted April 26, 2023 The original drawing shows the shaft held down with 2 side screws....very dangerous. I'm opting for two thrust bearings on the sides to hold the shaft into position with enough clearance so that it can move freely within the housing. This is just a draft. I sourced the thrust bearings and bushings for the motor. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted April 26, 2023 Author Share Posted April 26, 2023 I will most likely get rid of the indent on the shaft as this serves no purpose. The housing will need to be embellished with decorative reliefs. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted April 27, 2023 Author Share Posted April 27, 2023 (edited) Here is the base section. The two halves will be screwed together. The inside will house two thrust bearings on either side allowing the fan to hang upside down without falling out. It is tapered with a slight slope.

Paul Pierson Posted May 4, 2023 Share Posted May 4, 2023 Amazing!!! This is such an amazing project. And reading Jim Kovars insights which are so far above my understanding was a delight. And Anthony’s insights were critical imho. Kudos to all involved. Quote Link to comment Share on other sites More sharing options...
