In case one phase of a three-phase synchronous motor is short-circuited the motor will____________? A. not start B. run at 2/3 of synchronous speed C. run with excessive vibrations D. take less than the rated load

Synchronous motors are generally not self-starting because: A. the direction of rotation is not fixedB. the direction of instantaneous torque reverses after half cycle C. startes cannot be used on these machines D. starting winding is not provided on the…
