I'm needing help, I have an old Craftsmen table saw with a direct drive motor...n it's driving me nuts!
First the original motor, as you can see....I had to take it apart to clean it, done multiple times.....I reassembled it back, to the lovely smell of burning something and smoke....took it apart twice after that, got it working....put it back in the saw, attached the blade and now it grrrs and the shaft locks tight and trips the breaker....there is only a start n run winding, no capacitor...no centrifuge switch and no brushes..as can be seen in the next photos..there is just something called a "motor relay" believe its like an old mercury switch...if the table falls, locks the saw...
So now, I found a used motor, identical to this but uses a start capacitor as well as the "motor relay", now this was sold to me as used working....I went to power it on and it just didn't seem to have the power.....after a second, burning saw dust smell and smoke that wouldn't stop...so powered it down, went to another outlet and same thing...powered it off....came inside, removed the breaker/power switch from the control box....powers on now, no smoke but still not sure if it has the power needed....
Can anyone help explain to me, about these induction motors? Are the windings just on death's door because of a poor design and I am just pushing em over the edge or is there a fix etc? Really driving me bonkers...
