Hi All —
I am having a problem with the motor on my Bridgewood LTS-10 tablesaw. The other day I was ripping a thin strip off a plank to true it up when the strip got stuck in the no-longer quite zero-clearance insert and slowed the blade down (but didn’t stop it completely). I quickly stopped the saw and cleared the jam — but now when I turn on the saw — it doesn’t sound quite up to power and the magnetic switch switches off after about 10 seconds. Any ideas?
Information on the motor — it’s a 3HP 230V motor, about 5 years old (as is the tablesaw). The 230V line is good (it still runs my planer).

No expert here but you may have burned/shorted some of the motor windings. This causes the internal motor protection ( or in magnetic switch if it is there ) circuit to heat up a thing that turns off the motor. After it cools off it re sets. Not the same as the motor getting too hot. May have to pull the motor out and take it to a service center to have it checked with what is called a "growler".
Isn't that a great term for a tool ?
Like I said no expert here.

Until an expert comes along, I'm going to be a little more optimistic that roc and suggest it may be a contact within the saw - possibly in the magnetic switch which could have dropped one leg and is now feeding the saw 110 volts. Could be a connection in the motor itself. Take the cover off the motor and test the legs for voltage. It should be approximately 220 volts when energized.

I think that's my next step. I would be surprised if a 5 year old motor (and one that gets only weekend use -- I do have a day job) would have burned out a side -- although stranger things have happened.Dave M.
Just an uneducated guess, but I'd include checking the capacitors while you're at it.
