I'd replace it with the same motor controller. Google it. About $40 US
The reason is the price of that motor (Expensive!). That speed controller is compatible and proven to work. Else contact Dayton and ask them. HTH

If you are set on using that motor I'd buy the speed control from Grainger also. The CabMate comes with a 1/3 hp 2 speed motor (1725 and 1075 I think). Most wheels, blades, drums etc. have maximum speeds no where near 10000 rpm. A 1/3 hp 1725 $100 motor would have been adequate.

The machine wasn't used for years, and was given to me for free. The motor was already attached. I'll have to spring for the actual Dayton speed control or a new slower RPM motor.

Definitely not the third one. Not being as much a mechanical guru as some of the others on here, I would think any of the other three would work. The 1/2 hp draws my eye as that would have enough power (and maybe then some).

I would go with either of the Craftsman motors. They look newer and in better condition. Yes, definitely not the 1/6 HP one. It is much too small. Bob

Where you live, do you have a shop that rewinds/rebuilds motors? They would probably trade you or you can get something real cheap used.

Craigslist is good for cheap motors.

Motor one is perfect for that unit. With a multi-step pulley on motor or unit you can have several speeds. The 2nd motor is what Covington uses on their 18" slab saw so more than you need but would be good if you can get it at a low price. Motor 4 would work fine also. And I think you are right, there isn't many times when 1725 rpm won't work just fine.

If your resigned to replacing the motor, I'd spend the $15 just to make sure, the speed controller is very similar to the one suggested by Grainger except it HF's will handle more current. If you can get to the control potentiometer (what the knob is attached to, from the back side and spray some WD40 into it (with it unplugged) there is a slight possibility it is just dirty (couldn't hurt ).

Thanks for all the tips. I tried the WD-40 trick, but it didn't work. I might try the speed controller first, and if it doesn't work on the cab machine, I'll just use it with some of my woodworking tools.
