What would be the result of one phase open-circuiting while the motor was running?

Solution

If one of the phase open circuiting while the motor was running, it continues to operate at least for some time. But, if the motor operation depends on the how much load is connected to the motor.

and motor is operating less than 33% rated load it will continue to operate without any damage but if it is operated for higher load the motor speed will drop to zero. It will take 1-30seconds depending upon the amount of load and inertia of the load connected.
