If the winding of a single-phase induction motor is short-circuited, several things can happen:
Increased Current Flow: A short circuit will cause a significant increase in current flowing through the winding. This can lead to overheating and potential damage to the motor windings and insulation.
Loss of Functionality: The motor will likely fail to operate properly. Instead of generating a rotating magnetic field, the short circuit can prevent the motor from starting or cause it to stall.
Damage to Components: Other components, such as the capacitor (if used) or the power supply, could also be damaged due to the high current draw from the short-circuited winding.
Tripping Circuit Breakers: The high current can trigger protective devices, like circuit breakers or fuses, leading to power being cut off to the motor.
Safety Hazards: There’s an increased risk of fire and electrical hazards due to the excessive heat generated by the short circuit.
