Take a look at the picture above,
1. If the shaking head and the fan leaf are driven by the same motor, check if the fan leaf is loose, turn off the power, turn the fan leaf to align with the clamping position and tighten it.
2. If it is not the same motor, turn off the power and use something to move the lower wind flap to see if it is tight. If it is tight, it is stuck. Add some oil to both ends of the motor shaft and it will turn smoothly. If it is not stuck, it may be that the motor has burned out or the motor fuse has blown out
How to make a homemade small wind turbine
Use a puller to pull off the rear axle cover together.
Electric machinery (English: Electric machinery, commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is represented by the letter M (D in the old standard) in the circuit. Its main function is to generate driving torque and serve as the power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert electrical energy into mechanical energy.
First of all, you need a generator motor. If you are making a miniature wind turbine, the motor of a four-wheel drive vehicle can be used instead. After that, you put the rotor head on the front end of the motor. The blades are used to induce wind. When the wind blows the motor rotor to rotate, the two wire ends at the rear end of the motor can generate electricity. This is the power generation principle of the wind turbine, but this can only generate electricity. No practicality.
Secondly, if you need a truly practical micro wind turbine, you need to perform the following steps and prepare some materials, such as a diode and a voltage regulator (voltage stabilizing circuit). board), a battery, etc.
When you prepare these materials, you can first connect one end of the wire of the generator motor to a diode to prevent the generated power from flowing back to the motor, and then connect it to the voltage regulator (a reminder here) The voltage stabilizing power of the voltage stabilizer needs to be determined in advance, and it needs to meet the parameter requirements of the voltage generated by the motor to prevent the voltage stabilizing circuit board from burning) before connecting the battery to the voltage stabilizer (the battery voltage must also be stable. (within the rated parameters of the voltage regulator) and you're done. When the wind drives your motor to rotate, the electricity generated will be processed by the voltage stabilizing circuit and stored in the battery~
