If one-phase of a 3-phase synchronous motor is short-circuited, motor

will refuse to start

will overheat in spots

will not come upto speed

will fail to pull into step

Answer is Right!

Answer is Wrong!

A three-phase synchronous motor has three windings that are evenly spaced around the stator. When these windings are energized with three-phase power, they create a rotating magnetic field. This magnetic field induces a current in the rotor, which causes the rotor to turn in the same direction as the magnetic field.

If one of the phases is short-circuited, the magnetic field will be distorted. This will cause the rotor to lose power and stop turning.
