Unisaw 3 phase motor hummus won't start.

[Chris Hachet]

I had an electrician check that all connections are tight and measure line voltages on all three legs. One leg had a very slight voltage reading. He found a couple of places that needed tightening , also in the plug itself. We will see how it goes for now. Ran ok today. There may be a problem in one of the windings if it redevelops is what his guess is as suggested above. I'll keep the thread updated as to the result. Thank you all for the very good suggestions.

If there is a problem in the winding's it is usually not intermittent. I would double check your motor connections and see what you have there if problems develop.

Beat me too it, Peter. I was going to say that if you put Hummus in the motor, it's not likely to start.

So far so good, no more humming after all connections tightened and lots of use. Thanks for all the help.
