The motor on my table saw died and can get a motor that I think will work. It’s brand new, but made for an Evaporative cooler. Can i use that to replace it?

Did you check the overload trip on your tablesaw motor?
Here’s hoping you don’t have to replace the motor.

You might be able to use it, but how long it will last might be another story.

If it’s an “open” motor, might be a good idea to blow the sucker out with compressed air.

If that doesn’t work, pull it apart and take a points file to the starting points…over years they can get gummed up with fine dust and the arcing as they engage and disengage generates crud on the points.

or take it into a motor rewinder for a tune up. They’ll likely send you down the path of my next suggestion once you tell them the application.

After you’ve done all that, and maybe get it working, look for an enclosed motor. There’s a reason that folks use them on woodbutchery machinery. They are a tad more expensive

If it didn’t smoke or it just hums, there is a good chance it’s fixable.

Not really sure about a compressor motor.

It Humms for a few seconds and then trips the breaker. I did a lot of research and the first clues led me to think it was the Capacito, so i replaced it, which didn’t work. Then i came to believe that it may be the bearing’s so I lubed them up godd and had them spinning pretty smoothly. I cleaned it out of cobwebs, dust, etc… at that time too. Lastly, I thought it might be the on and off switch (previous owner had swithed it out with a standard light switch like uou may have to turn your lights on your wall). It looked good, just had some sawdust in their which I also cleaned out. All this to no avail, as it is still doing the same thing which leads me to where I am today.

Might be the start switch. Give it a spin if you can and see if it goes.

Swamp cooler motors rely on the air they pull through the cooler for cooling it’s self they do not have a cooling fan built into it like other motors do. I think it would overheat and also quit working in a short time. yes if you look I’m in Ohio and coolers like that are not used here as it’s already to humid bit I liven in Phoenix for many years and they still use them out there I think if it were me I would find a motor hospital and put it in there to be checked out could be a cheep fix or they could find a direct replacement for it. good luck, Paul

Most electric shops can rebuild it for you.

Yup. May have a bad centrifigal switch. Humming is a lot better than no humming or it was smoking.

I would caution you against using the swamp cooler motor for the TS. Like many others, I’m guessing the problem with yours is very simple (I think you’ve blown a capacitor). Those are extremely easy to check, there should be some humps (or hump) on the motor (maybe a box), loosen one up and smell, then look for an oily substance around the innards. Either (and both) mean you have a bad cap. they run anywhere from $8-$20 or so. Go to an industrial supply, electrical supply, or motor shop and get another one.

Thanks for the advice guys. Fred, already switched the Capacitor, but that did not work. I think I’m gong to take it in to the “motor hospital” as paul suggested. Thanks again to all.

If the motor is toast, look for a TEFC motor from Baldor. A Lesson if the Baldor is out of your budget.

Them motors actually do require smoke to operate.

Once the smoke escapes, they don work no more.

Just like most other electrical appliances….
