My Delta Unisaw has been working fine for fifteen years. Now all of sudden when I push the start button the motors spins very slowly tiring to get up to speed, but does not and after about five seconds trips the breaker. I suspect one of the two capacitors. Could it be anything else? Thanks.
About ten years ago I thought my table saw motor had died. I looked at the price of new motors and priced what it would cost to repair.
Before going all of the way and buying new, I took it to a small motor repair shop for their evaluation. Fifteen bucks later after the repairman showed me how to remove the small wood chips that were preventing the contacts in the motor to close, I was on my way home.
Now periodically (every couple of years)I disassemble the motor cleaning out sawdust and wood chips from the inner recesses of the motor as part of the preventive maintenance of the saw.
Similar to previous posters, I've had to change the capacitor (~10 yrs ago) on my 1981 Unisaw motor and clean (~2-3 X yr) the contact points on my bandsaw motor, so check both before buying new.
Probably right but I had a similar problem a few years ago. I lost half the 110 in my house so the motor lost half its power and would not start. Every thing working OK in the house?
Start capacitor is open. Current in the start winding is low or non-existent and the run winding like a third or forth gear is pulling away from a stop. Not designed to.
Simple to change, most have plug > That's probably it.
