Annu,

I guess a possibility is that the motor is being controlled by only switching one line vs both. In that scenario, your contactor could be fine and the short to ground is in affect as soon as you apply power to machine.

Annu,

If you measure a short to ground from any of the two power lines that is a good test. The winding is low resistance and will measure low ohms even on a good motor between the two power lines.

You definitely have more issues than just the motor. There should not be power to the motor w/o pushing the start button.

Can you confirm that brake function is normal on saw and shaper?

Good luck.

?Well Folks,

My nightmare is confirmed.? The planer motor has a short in it.? I've had the machine for less than 2 years and have maybe a total of 40hrs of runtime on it.? Bringing Felder out to change out the motor will cost an arm and a leg.? I'm hoping with some direction from felder and a lot of help with some of the folks I work with at the chemical plant, I'll be able to change it out.? I'll keep ya'll posted.??

P.S.? Checking for the short was easy...we checked continuity between the two wires to each winding and the ground on the motor quick disconnect.
