Why does the car fan turn on and off intermittently?
1 Answers
Here are the reasons why the electric fan does not rotate: Poor motor lubrication: The fan does not rotate because the motor lubrication is insufficient, making it difficult for the motor to drive the fan blades after installation; Motor overheating: Motor overheating can also reduce the motor's load-bearing capacity, lowering its effective power and making it unable to drive the load; Decreased capacitor capacity: The capacitor capacity may decrease, reducing the motor's starting torque and making it unable to drive the load; Prolonged motor usage: If the fan has been used for a long time, the motor may wear out. After the motor's shaft sleeve wears down, it can easily burn out. Prolonged use can also increase the motor's internal resistance, reducing its load-bearing capacity and making it unable to rotate the fan blades.
