Fan start capacitor connection method

Fan start capacitor connection inspection measurement method

Household electric fans use single-phase ac motors, so they only need one live wire and one neutral wire to work normally. However, in order to protect the motor, an additional electric fan starting capacitor is required,this can avoid burning the winding due to excessive current when starting.When installing this capacitor, you first need to check and measure the motor. In addition, there are three wire ends on the motor.Adjust the multimeter to the electric barrier, and measure the resistance between the wire ends respectively. The two wire ends with the resistance value Max are the places where the capacitor is installed.

Fan start capacitor connection method

The correct connection method of the starting capacitor of the electric fan, the electric fan generally uses a non-polar capacitor, so there is no difference between positive connection and reverse connection, and the standardized accessories do not need to be welded,just tighten it with the screws in the original way.However, you must pay attention to the specifications when purchasing a new capacitor. Choose the same model. Too large or too small may cause new problems, especially if the capacitor is too small, it will not have the proper start-up and protection functions.When the current is high, it may cause the fan to click and be completely scrapped.

Precautions for Connecting the Fan Start Capacitor

The connection method of the electric fan starting capacitor is very simple, so if the accessories can be bought, the user can complete the replacement by himself.However, those who have not been trained must pay attention to safety during maintenance. First of all, the power must be completely cut off before operation, and it must not be operated with power on.Another thing is that the neutral wire and the live wire should not be reversed.For electric fans, the neutral and live wires of electrical appliances reverse connection can also work normally,but the electric fan will still be charged after it is turned off, which will increase the risk of electric shock and leakage.
