Hello All,
Thank you for your earlier advice on rehabbing my dad’s table saw. The decision has been made to look into getting a new motor. The local place in town wanted $135 to repair the old one. Where should I start? I need a single phase 1 hp motor. I know companies like Baldor make motors, but not where to go to just outright buy one. McMaster-Carr carries 1 hp motors, but in excess of $200. Thanks for any advice.

I am not familiar with the rest of your rehab. What kind of saw is it? I have some extra saw motors for Delta Contractor saws
It's a 27 year old craftsman contractor tablesaw. It would take about $400 to buy a new saw that would be it's equivalent. And my parents don't have that kind of money.Datachanel

My experience with replacing motors and not rebuilding them,(and I've,changed out a lot of motors) is the new one is often just a little bit different. And then it turns into a real pain in the butt.
Good Luck. Walker1
Hi,
As an industrial electrician, my experiance has been that you are better off replacing a small motor than having it rebuilt. Good sources for cheap motors are ebay and your local newspaper classifieds. All you need is the nameplate data on the old motor particularly the voltage, frame size, RPM's, and whether is an open or TEFC (totally enclosed fan cooled) motor.

Most replacment motors are rebuilt motors, even if you buy them from a big supplier. They go with the cheapest rebuilders that can handle the volume, and just replace it if it fails under warranty.
And if you buy a motor off E bay, and there's a problem, Good Luck!

You could try Grizzly http://www.grizzly.com/catalog/2005/main/188.cfm?
By the way, your original probably has a NEMA 56 or 56H frame, spins 3450 rpm, has an open frame, and may be dual voltage, though that's not a necessity. If you go with a TEFC motor, be aware that some of them are longer/larger than the originals, and can have interference problems when tilted to 45 degrees.
Be seeing you...

It may be hard to find a new motor for that price. You may want to take this question over to http://www.owwm.com. Lots of folks over there who know old machines and probably someone with a replacement.

Baldor makes GREAT motors.. But a bit expensive.. You get what you pay for..
Nothing wrong with a re-built motor IF they replace the bearings when they do it!
