Customer Question

I have an older model Rockwell Tablesaw, a Unisaw. It was probably made in the 80's, and it has a 230V single phase motor, 15.5A. This morning it would not start. I tracked the power down to the panel on the back, where it looks like it either dies in a micro switch or a relay.
Does any of this make sense? I have pictures to help ID the problem
Thanks,
Bart

A motor of this type has a capicator
That helps it to start (simply put.
It is usually grey or silver and looks like a small canister.
It will have two wires pluged into it . Not hard wired.
Make sure the saw is unplugged when you mess with this.
They are pretty inexpensive and usually mount with a screw
On each side or under a strap . They are pretty easy to find locally but can be ordered
Using the numbers on it . Replace and plug the two wires back on .
Some motors have a dark grey round plastic one mounted directly to the motor. Same procedure for replacing.

This is a common problem but not the only one that could cause the motor
Not to start. The brushes in the motor could also be bad.
Usually you will hear a difference in the sound of the motor before the brushes fail.
They are similar for most motors but they do require some experience to replace.
Let me know if that is what you suspect and I will help you through it.

Just touching base to see if you have made any progress.
I'm doing a little research on your motor.
Just a thought did you check the safety switch ?
