Fan capacitor wiring: Find the line with the largest resistance in the motor, connect the capacitor, and plug in the power supply.
The specific steps are as follows:
1. Use a multimeter to measure any two of the three wires, find the one with the highest resistance, and mark it 1.
2. Connect the capacitor to mark 1.
Usage precautions:
1. Make sure there is lubricating oil in the fan shaft, otherwise the motor with the fan blades on it will not be able to move. If you are at home, you can choose to turn off the power and then turn the fan blades. If the rotation is stiff, there is basically no lubricant.
2. Wear and tear caused by long-term use. If a fan is used for a long time, the motor will wear out, and the motor bushing will easily burn out after wear.
3. The fan does not rotate due to overheating. There is a motor in the fan device, and there will be an overheating circuit breaker in the motor. If a short circuit occurs in the coil winding, the heat will increase in a short time, and the motor will "strike" and stop moving.
4. The starting capacitor capacity becomes smaller. When the fan is used for a long time, the capacitance capacity will decrease, causing the motor's starting torque to become smaller and unable to drive the load.
5. Many times the reason why the fan blades do not rotate is due to poor maintenance. If the fan blade rotates stiffly after turning off the power, you should drip some lubricating oil into the shaft so that it can be lubricated so that it will not affect the motor to drag the fan blade.
6. For the fan blades not rotating due to wear, the easiest way is to replace the parts, especially the bushing, which is easy to burn if worn.
7. If the capacitor capacity becomes smaller and the fan does not rotate, you can remove the capacitor and replace it with a new capacitor of the same model. It is recommended to choose a capacitor that is 20% larger than the original capacitor, which will have better rotation. Effect.
Can a large capacitor be added to the homemade wind turbine after rectification?
The capacitor plays a starting role in the fan.
If its capacity is too small, it will affect the starting torque and the speed.
General users have difficulty in detecting the capacity of capacitors. You can do this:
Turn the fan blade by hand. If it rotates flexibly, the capacitor capacity is insufficient; if the fan blade rotates flexibly, it is not a problem with the capacitor, but with a defective bearing or bushing. Oil. Ask a mechanic to open it, clean it, and refill it with oil.
A large capacitor can be added to the homemade wind turbine after rectification. A wind turbine is a device that converts wind energy into electrical energy and is mainly composed of blades, generators, mechanical components and electrical components. Depending on the axis of rotation, wind turbines are mainly divided into two categories: horizontal axis wind turbines and vertical axis wind turbines. Currently, horizontal axis wind turbines occupy the mainstream position on the market.
