What will happen to a single-phase motor if capacitor of motor is short-circuited:
- The motor will burn right away
- The motor will not start
- The motor will run in the reverse direction
- The motor will run at reduced RPM
Correct answer: 2. The motor will not start
If capacitor of a single phase motor is short circuited, the motor will not start.
A single phase motor not self-starting. Rather the capacitor helps the motor in starting. Now if the capacitor is short circuited, then, there will be no starting torque and the motor will not start.
