If the capacitor of a single-phase motor is short-circuited
Right Answer is:
The motor will not start
Capacitor motors are split-phase motors with a capacitor added to the auxiliary start winding, main run winding, or both to improve the operating torque characteristics of the motor by causing a greater phase shift in the current between the main and auxiliary start windings.
The capacitor limits the starting surge current to a lower value than is developed by the standard split-phase motor. When the capacitor is short-circuited high inrush current will flow in the winding which may burn the starting winding of a single-phase induction motor.
If the capacitor is short-circuited, there will be zero starting torque, and as a single-phase induction motor is n0t self-starting, Therefore the motor will not start.
