Rockwell/Delta table saw power issue

[Kenny2]

Model # 62-042 contractor saw. New to me. Starts and runs quietly and smoothly. However under any kind of load in any kind of material, the blade slows way down, and will stop if you don’t. Have installed new blade and new belt. What are my next steps? Remove motor and take to shop? Was hoping to fix myself, but that’s “pride talking”.

Thanks, Kenny

Not familiar with that exact machine,but many such motors use a centrifugal switch attached to the non-drive end of the motor shaft to switch capacitors in or out of the circuit when the motor reaches a certain speed. Failing to do this might result in such symptoms, depending on tbe motor design. I suggest removeing the end cover of the motor housing to see if it has become packed with sawdust, interfering with the switch function.

Check all the caps. Good advice. Also, be sure to use a rip blade. Even a new crosscut blade could bind. Combo blades work with enough power, but a small saw benefits from dedicated blades for most jobs.

Is the blade slipping per chance? Suggestion is to confirm it's the motor and not the arbor nut not gripping well.

Is the motor perhaps wired for 240V? That would produce those exact symptoms.

I'm with Frank.  Did you have to put a new cord or plug on it?  A 240v will run on one leg of 120v but not correctly.  If it is wired correctly for your power source then definitely check the caps.  Even if you bought new caps and that wasn't the fix it would be cheaper than the bench charge at a motor shop (if you can find one; they are like hen's teeth out here). Please let us know how you make out

The motor is underpowered. To rip 2" hardwood or thicker you need sharp blades and patience. Or a bigger motor. I think it is 2 hp. 3hp is a better ride.

Have you considered checking the speed and feed?
