This motor was taken out of service at the Lindale Mill site some time in the past. It is a Westinghouse Style 1167961 with Serial number of 20742.  It is very unusual in that it is completely open, with everything smooth and rounded. Even the windings are covered in an epoxy which is rounded and smooth.  I am guessing that by making everything smoothed over, cotton lint has nowhere to collect!

I would like to know when this was built. It may possibly not be as old as it looks. There is a chance they kept the old style looks to make the lint-free design. Hopefully a Westy expert can look at the numbers and chime in!

Sadly, someone butchered the shaft with a torch, leading to the very short shaft seen below. There is still enough shaft to mount a taper-lock style pulley.



The tag:


So, the question which will certainly be asked is, "Does it work?!?"  So to answer that urgent question - here is a video of some measurements and checking out of the motor...

Thanks Henry.

Will do a full teardown of this one someday and get better close-up pictures and video of the sealed winding. 

For now, it's got a nice dry place to sit where it's not in danger of getting rained on or damaged.

That logo looks to be from the late 1930s.

Thanks for the info Michael. I guess it is pretty old!

So; today I went to the industrial supply stores today and got some goodies!  Unfortunately, they had to order the bearings for the Sturtevant blower shaft.  But they did have a bearing for the Westinghouse Lint-Free motor.

First, I took the motor apart. It was rusty...


The rear bearing (right side in the picture above) was serviceable. I was able to repack it and reuse it.  The other on the left was totally corroded and destroyed. There was a lot of rust buildup on the rotor, too. That has to go or it will cause drag between the rotor and stator...

The inside of the stator was also really corroded.


Notice the fully encapsulated winding? Covered in fiberglass.

First, I cleaned the inside of the stator with a Scotch-Brite wheel on a die grinder. Also, I gave it a nice spray of Smoke Grey Rust-Oleum.


Then, the end bells got cleaned with Purple Zep soap and dried.


With new paint on the end bells and the rotor cleaned up, things can start going back together..


Rotor back in the stator....


And motor back together!


And with pulley!


I didn't have enough paint to finish the job!  I did paint the inside of the motor so that I won't have to take it apart again to finish the painting.

So..... How does it sound with new bearings?  Pretty good!
