It sounds to me like like you have a incoming power issue, motor contactor or a bad 3ph. motor. Check your incoming power with a volt meter and check the leads going to the motor, they should all be tight and they should all have 208/220/230 volts going to them, whatever your set up for.

It took a minute, but I got it.
Old electrician's joke. I almost posted it earlier, but I figure Jambowash would not appreciate it.

My bet is the power is fine. The motor is fine. You only have two phases coming through the contactor.
