Three Phase Motor?

Question

If one phase is lost,will the motor tripped or stop or will it continue to run at a slower speed.

Answer 1

It will spin slower, if it is loaded it may stop. It may not trip, that will depend on other components of the system. If you are using an intelligent starter that monitors voltage, current, phase difference, ect.

If you mix windings on a phase, it will not turn, just bump and buzz.
