What happens when one phase of a synchronous motor is short circuited?

What happens when one phase of a synchronous motor is short circuited? Correct Answer Motor will burn out

Single phasing in synchronous motor:

  • Single phasing in a synchronous motor means that one of the three phases of the supply has been cut off due to any reason, and one phase fuse blown or removed.
  • The motor, when already running, keeps on running as a single-phase motor making a characteristic noise.
  • This is a single phasing condition because the current in both the remaining lines now is the same single current.
  • In order to compensate for the lost current, the motor starts drawing more amount of current heating the motor even in some cases could burn the motor.
