I recently acquired an older powermatic 66 and need a replacement motor. It is a 3hp single phase, I need to know the frame type so it will fit. Any help is appreciated. Also any opinions on Leeson motors?

Leeson are very good motors, I have one on my DC….some of them are now made overseas, but for the most part they are still USA motors. I think those saws came with a Baldor, and it’s a C face motor (again: I think). Check around for a 145TC, IPh, 3 hp and see what you can find. I’d bet PM also still sells them, but it will cost a lot more than just finding one from a motor shop. Are you sure the existing motor can’t be repaired?

Why do you need a replacement ? If it burnt down have it rewound.

Cheapest you will find right here:

In my neck of the woods it’s cheaper than having it rewound…..I’ve purchased this and many other motors from these folks, great people to deal with.

That is a lot cheaper than some others I saw, PM wants something like $650 (+/-) for it.

That seems like my best choice. That’s for the information.

Since the motor runs, but doesn’t come up to speed (as per your description here), I’d be more inclined to figure out why, rather than fork out the money for a new one. Could just be something simple (like trying to run it on 120v) and inexpensive to fix. Since you have already written the motor off, it sure won’t hurt to try :)

I checked the electrical possibility I’m going to try replacing the running capacitor

I’d test it with a cheap multi-meter first, so you can verify it’s bad before going out and buying a new one… unless you just like buying parts and hoping that was the problem :) Could also be a stuck centrifugal switch, bad bearings, caked up with sawdust and other junk, etc… Might want to consider opening it up and taking a peek (and giving it a good cleaning at the same time).

Cheers,
Brad

A bad start and/or run capacitor are often the culprit. If you are unsure of how to test them, take the motor to a shop for anslysis. Fixing it is often far cheaper than a new or even a rebuilt replacement.

^^^^This, if you aren’t all that sure of what you’re doing…the diagnostic charge/bench fee/whatever should be fairly low (ask first). If you’re fairly adept at such things, do a little diagnosis yourself.
