    I have a 550v elec motor on a band saw, after about one minute of run time load or no load the motor shuts off, after one minute i can restart it... why would this happen?

    Im thinking thermal shut down but not sure how to test.....

    Check for heat on the motor frame, look for a pair of small gauge wires exiting the motor at the connection box, measure the continuity across the pair when it cuts out.
    Do you have a wiring diag of the saw?

    550VAC is not for beginners!
    One mistake and you will be in a hospital...or worse.
