Hi all, our old bandsaw stopped working so well. It has no
torque/ power
and when you turn on the unloaded motor it sometimes runs
backwards.
The thought here is that maybe a start or run capacitor had gone
bad...
but we are all mostly clueless when it comes to motors. Any
ideas
before I try and get the motor out.
(Oh dear.. I think it's a three phase motor... (no cap))
Maybe check the three voltages?
Or a bad motor

Never mind. problem fixed. (Sometimes all I need is a smart
audience.)

You told us the symptoms, so what was the cause?
We all started out clueless and had to learn somehow.
Oh sorry, one (or two) of the phases was missing. Someone
had been abusing the power plug into the wall outlet...
Five minutes with a screwdriver and all was good.
