AO Smith Motor Help on a 10er

[Olliew72]

I'm back from the motor shop. I've used these guys before and it's a great old shop. They're actually a licensed AO Smith distributor and repair shop.

The bailing wire did get some chuckles.

At first they were trying to explain to me that a normal repair would be about $125 bucks and was the motor worth it to me. Then I showed him the motor and they let me use their bench and tools to disassemble it for them to see. They'd never seen a centrifugal switch that rides on phenolic, but they could tell that's the only way it could be on this motor. We all scratched our heads and maesured a few things. After 30 minutes of that he said that he wouldn't feel right taking it on now that he'd seen the insides since they gaurentee all the motors that they work on and he would feel obligated to replace all the cloth covered wiring inside, which would be a lot of work.

So I put the motor back together and we both agreed that something's wrong, but it was staring us in the face and neither of use knew what it is...

I guess I'll spend some more time on it at home, or give up and put a used Ebay motor on the 10er.

Do you understand what I meant by forming the contacts?

Yes, I understand JPG. Thanks.
Here's what I was able to score on Craigslist for $30. I hooked it up an woohoo. Now I can take my time to try and figure out the original motor.

Not to take the woo hoo out of your sails, the larger shaft will be an 'issue'.

Nice motor for $30 fer sure.

Hmm, not sure if the picture distorted the view of the shaft, but it's the same diameter. It is a 1/2" shorter, but the pulley fit on just fine. The only issue is that with the capicitor casing on the top of the motor, it just barely fits under the headstock. But it's all together now and seems fine.

Hmmmm is that an Emerson motor that CAN be reversed?

[Olliew72]

Yes, it can be reversed. I'm wondering why you'd want to run a SS backwards though? The guy I bought it from said that his dad, who passed away, had bought it as a replacement for his table saw and never got around to installing it. It was just sitting on a shelf. Lucky find for me.

Not only is it reversible, it is also a dual speed motor. It can be used at either 1140 rpm or 1725 rpm.

You may have a gold mine there, dude.

Outstanding motor for the 10ER. You need 2 20 Amp motor rated DPDT toggle switches, one for the reversing of the motor and one for the speed change. You still need the ON/OFF switch for power. I would put them in a box and attach it to the motor or motor plate. I seen several 10ERs with larger motor and capacitor on top where the two boards used for the table was separated so the capacitor would fit between the boards. This was the simpler method I have seen used for larger motors.

Cannot tell for sure from the pix, but if the mounting frame is separate from the motor itself(mounted on round rubber suspension) you may be able to rotate the motor relative to the mount.
