Haha, a race car's engine can usually produce electricity. The motor is divided into two parts: First, if you don't understand, the outer casing is the stator, which has magnets inside. rotor, which has a copper coil on it. The stator magnets produce magnetic lines of force. When the rotor turns, the copper coil above it also turns, which can cut the magnetic field lines emitted by the magnet on the stator, so that electrons flow through the copper wires. It will generate current and produce electricity
Does the wind turbine rotate clockwise or counterclockwise
If you use a charger, please connect a diode in series to one end of the output line. If it is used for lighting, it only needs a drive motor to rotate.
The drive method can be tap water, bicycle,manual wind, etc. I suggest you use tap water. holes in the wind blades. Bao Chenggong buys heat capacity glue and makes a box to enclose the water flow and it will be perfect
Learn how to use a computer fan to modify a small generator problem
Does the wind turbine rotate clockwise or counterclockwise? The hour hand must depend on the shape of your wind leaf, which determines the direction of rotation of the motor;
On the other hand, the small motor must be a DC generator, and the direction of rotation determines the direction of the voltage and current generated;
So in the end it depends on the end of your power consumption (usually divided into high and low voltage, simply speaking, positive and negative poles) to determine the direction of voltage and current, such as for energy storage, lighting bulbs, etc.
1. FridayThe computer fan uses a 12V DC power supply, then uses a circuit to drive the fan. The general diagram of the fan circuit is as follows:
2. If there are 3, if there are two wires, one of them is the speed measurement signal output wire. If there are four wires, the other two are the speed measurement and speed regulation wires.
3. Therefore, it is impossible to create a small generator using the computer fan.
4. If you want to modify a small generator, please use a general DC permanent magnet motor, that is, a small motor commonly used on toys. As long as the speed is fast enough, it can generate. a small current. As shown in the picture (the picture below is the effect of blowing an electric fan against it, and the LED is on):
