This was about the same fan, a Holmes brand.

Reducing the cogging was the 'New Idea'. That is the main problem with these.
With 4 magnets the cogging is almost totally gone.

And it sure was easier than a re-wind!

The fan blade from this motor is now turning a tiny little induction conversion.
This one turns just as easy, and the other one even has bearings!
(check my photo files for Ugly20 or WideOpenSpaces)

I believe a 'Teflon' carrying oil (like 'Slick-50', 'Greased Lightning' or 'T-Plus') will help the bushings spin much more free and last longer.
Just personal experience, but T-Plus is in all my cars because it saves far more than it costs in gas alone, and they run cooler.
No connection with any of them and me.

Keep an eye out for another donor fan to try this.

  You don't really know what the rpm is ...do you?
Here is a quick simple way.....


  count the number of threads per inch ...grab the nut and see how far it travels in 10 seconds.
...if you're really a new guy you might have missed this.....
