Damage to the starting winding
Opening of the centrifugal switch at the correct speed is crucial for the safe operation of a motor. If the centrifugal switch fails to open at 70 to 80 percent of synchronous speed, it can lead to damage to the starting winding. Here's how:
- Role of centrifugal switch: The centrifugal switch is responsible for disconnecting the starting winding of the motor once it reaches a certain speed. This is essential to prevent the starting winding from being continuously powered during normal operation.
- Impact of not opening: If the centrifugal switch does not open at the specified speed, the starting winding will remain energized even when the motor is running at higher speeds. This can result in overheating of the starting winding due to excessive current flow, leading to insulation damage and ultimately failure of the winding.
- Consequences: Damage to the starting winding can significantly reduce the efficiency and lifespan of the motor. It can also cause the motor to draw more current than intended, potentially leading to overheating and other electrical faults.
Therefore, it is important for the centrifugal switch to open at the correct speed to ensure the safe and reliable operation of the motor, preventing damage to the starting winding and other components.
