I took a few pictures at work showing the motors i rebuild. I only take picture of the ones that actually take some work, not just putting a new motor on a pump. So I have an album on the site now here is the link.

I will have more new pictures this week.

It appears you installed new rotor and bearings, but did you rewind anything? I'd like to see those pics (if you have them)

Yes we do re-wind, but not much lately. However right now we have an old westinghouse direct drive motor that was burnt up. We gave a price to the owner to get it re-wound, since it is an obsolete frame, so as soon as we get the ok, and start, I will take some pics as we re-wind it.

That would be great, I don't hav eany good pics on this laptop, I have hundreds on my other laptop with no way to retrieve them at the moment. I have a picture of me standing inside the stator widings of a 2500 hp 4160v motor with my arms over top of my head and still could not touch the top of the windings. That motor was huge. The company that set it in place for us, damaged the windings when setting the motor into place. It shorted phase to phase when we started it. The building had already been built around the motor. Steel workers took off the roof of the building and we took it right out the top and got it rewound. The crane company had and millwrights had to eat that one.

Motors are great, I love 'em.

I saw one a few years ago that I hadn't seen for a very long time; a synchronous type. Unity power factor. With a wound rotor, that used DC for power factor correction. Pretty old, but still ran!
