AC Fan Motor Capacitor Wiring Diagram PDF
An AC fan motor capacitor is a type of electrical component that is used to start and run an AC fan motor. The capacitor provides a temporary boost of electricity to the motor, which helps it to start up. Once the motor is running, the capacitor is no longer needed and it simply provides a "buffer" between the motor and the power supply.
The capacitor is typically connected in parallel with the motor windings. This means that the capacitor and the motor windings are connected to the same power source, but they are not connected to each other. The capacitor is typically located close to the motor, and it is usually mounted on the motor housing.
The size of the capacitor is determined by the size of the motor. The larger the motor, the larger the capacitor will need to be. The capacitance of the capacitor is also expressed in microfarads (µF).
The following is a diagram of a typical AC fan motor capacitor wiring diagram:
In this diagram, the capacitor (C) is connected in parallel with the motor windings (M). The capacitor is typically rated for 250 volts AC and has a capacitance of 50 µF.
The capacitor is used to start the motor by providing a temporary boost of electricity to the motor windings. This boost of electricity helps the motor to overcome its inertia and start rotating. Once the motor is rotating, the capacitor is no longer needed and it simply provides a "buffer" between the motor and the power supply.
If the capacitor fails, the motor will not be able to start. The motor may also run slower than normal or make a humming noise. If you suspect that the capacitor is bad, you can test it with a multimeter.
Here are the steps on how to test an AC fan motor capacitor:
- Disconnect the capacitor from the motor.
- Set your multimeter to the "capacitance" setting.
- Connect the positive lead of the multimeter to the positive terminal of the capacitor.
- Connect the negative lead of the multimeter to the negative terminal of the capacitor.
- Read the capacitance reading on the multimeter.
If the capacitance reading is within the range specified on the capacitor, then the capacitor is good. If the capacitance reading is outside of the specified range, then the capacitor is bad and it will need to be replaced.
Replacing an AC fan motor capacitor is a relatively simple task. The following are the steps on how to replace an AC fan motor capacitor:
- Disconnect the power to the fan motor.
- Remove the old capacitor from the motor.
- Install the new capacitor in the same location as the old capacitor.
- Reconnect the power to the fan motor.
Once you have replaced the capacitor, the fan motor should be able to start and run normally.
##Conclusion
An AC fan motor capacitor is an important component of an AC fan motor. The capacitor helps the motor to start and run properly. If the capacitor fails, the motor will not be able to start. If you suspect that the capacitor is bad, you can test it with a multimeter. If the capacitor is bad, it will need to be replaced.
