Question 125Electricity & Electronics - 1st Asst/Chief

The correct answer is C) The winding would burn out. If the centrifugal switch or relay that cuts out the starting winding of a split-phase induction motor fails to open while the motor is in operation, the starting winding will remain energized. This will cause an excessive current to flow through the starting winding, resulting in the winding overheating and eventually burning out. The motor will not over-speed (A) or run at a reduced speed (B), and there is no time delay mechanism (D) that would stop the motor in this scenario.
