Louis Luu Posted October 22, 2023 Author Share Posted October 22, 2023 (edited) Bearings for the base. Bought both types to try out. Edited October 22, 2023 by Louis Luu 1 Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted October 22, 2023 Author Share Posted October 22, 2023 The bracket is modified to accept oil bearing to reduce friction and strengthened by closing the side bracket into one single unit. 1 Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted October 22, 2023 Author Share Posted October 22, 2023 Will draw up the bottom portion of the base when my bearings arrive. Motor will be drawn last. I'm debating about making the strut balance out of lead? Will do both I guess as I don't really know how much mass to put on it. Quote Link to comment Share on other sites More sharing options...

A centrifugal start stamp steel Westinghouse fan head would be one functional example. You simply drill into the front motor housing at the 3 o'clock position to mount a small steel bar that allows a weight to be slide adjusted for proper tilt position. Unless your intentions are to recreate an early 20th GE DC fan motor. 1 Quote Link to comment Share on other sites More sharing options...

Liking it and reproducing it are two different things. A prototype model to see just how well it functions first may be wise. I am sorry to say there are no examples of Ralph's oscillating concept advertised for the market in electrical trade. The stationary Westinghouse stamp steel centrifugal start fan head could even be modified to the 4 strut configuration. FWIW. Quote Link to comment Share on other sites More sharing options...

It is not a post mounting under the fan head like the oscillator, but modifications could be made if necessary, without great difficulty. They are fairly abundant out there, self starting, and come in 4 or 6 wing models. 1 Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted October 22, 2023 Author Share Posted October 22, 2023 2 minutes ago, Russ Huber said: I have one of the Westinghouse you are referring to. Unfortunately, the size of the motor will be a bit too big for the pendulum. I do like the look of the early GE DC style so I will be aiming for that look. It is time I learn how to do the winding anyway. I can sort of see how this pendulum would work out but need to see it working to believe it. The bearings will be arriving next week and I will continue to draw the bottom of the base. The bottom portion of the base has two plates allowing adjustments for the stopper....I figured out how to make that happen. 1 Quote Link to comment Share on other sites More sharing options...

Using it to make a prototype would be easier on the pocketbook. Your project, your money, your call.

Louis Luu Posted October 28, 2023 Author Share Posted October 28, 2023 From what I can tell, it is the torque or the spinning of the stator that keeps the rocking motion. Won't know till I try it. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted October 29, 2023 Author Share Posted October 29, 2023 (edited) The base is done. I've made it so the current bearings I have can pressure fitted between the top plate and middle plate. The top plate does have clearance so it can swing without obstruction. The middle plate and bottom plate has spacers for the stoppers to freely adjust with a thumb screw. The bottom plate will be locked to the middle plate with screws. The top plate will be free to spin but not come loose....has a middle screw that will allow for tension and prevent it from coming off. The base is also designed to be heavy so it will not move when swinging back and forth and rotating. The motor will be the next obstacle. I do like the DC GE look but will be utilizing a simpler setup base on the the Porter Motors which I am more familiar with.

Louis Luu Posted October 29, 2023 Author Share Posted October 29, 2023 The stopper will be cut to size once the motor with the handle is done. The ring allows the stopper to be positioned to control the amount of rotation. Quote Link to comment Share on other sites More sharing options...
