1. Changing a household electric fan motor into a generator does not require modification (the running capacitor cannot be removed). As long as the motive force is used to drive the rotor to rotate at 1500 revolutions per minute, 220V electric energy can be output at both ends of the main winding.
2. The rotor has been changed to a permanent magnet, so there is no need for an operating capacitor. The original stator winding does not need to be modified. The two terminals of the main winding are used as outputs; if the rotor is changed to a 2-pole permanent magnet, Magnetic, the motive force must be used to drive the rotor to rotate at 3,000 rpm.
Extended information
Notes:
1. See the random file
The motor fan is installed randomly Instructions for use, product certificates, electrical circuit diagrams and packing lists must be checked and components must be checked.
2. Look at the appearance of the motor fan
Carefully check whether the motor fan grille and fan blades are obviously deformed. The fan blades should be rotated briskly and flexibly, and should not always stop at the same position.
3. Look at the starting performance
The starting performance is an important quality indicator of the motor fan. During the inspection, at slow speed and 85% of the rated voltage of the power supply, the motor fan should be able to start from standstill and operate normally. The shorter the time it takes for a motor fan to start to normal operation, the better the starting performance of the motor fan. .
4. Check the speed regulation performance
After power is turned on, there should be no abnormal noise in the mechanical transmission part of the fan. When the electric fan is running at high, medium or low speed, the motor and fan blades should be stable, with small vibration and low noise. The motor fan should shake and stop quickly without interruption, stagnation or jitter.
5. Check whether there is electric leakage
After the motor fan is powered on, if you feel numbness and electricity when you touch it with your hand, use a test pen to test. The test pen also has a luminous display, which can determine whether the shell is leaking or not. want.

Power generation process:
Fan blade---gearbox---DC motor---rectifier bridge (polarity protection)----battery
Principle:
After wind power The rotating blades (similar to electric fan blades) drive the gearbox to make the DC motor rotate at a speed exceeding the rated speed. At this time, the voltage generated on the motor will be equal to the motor working voltage. Generally, 12V or 24V is selected because the battery generally has these voltages.
Difficulty:
To make a gearbox, you need to calculate the transmission ratio. For example: the rated speed of the motor is 3000, the fan blade rotates 10 times per minute, and the motor end reaches 3000 through the gearbox. rpm. At this time the transmission ratio is 1:300.
The above data are obtained from the small-power hand-operated generator model I have made and are for reference only.
What is the name of the infinite steering mechanism of small household wind turbines with the wind?
24 hours multiplied by 500w equals 12000w or 12kw.
I guess the poster is doing engineering inspection.
The average daily wind speed is 7-8m/s How many hours can it last?
We assume that it is only 4-5 hours in general areas. Then you need about a 3kw fan, which can supply 12kw to 15kw power every day. The premise is that you have to ensure that there is so much wind every day. .
If the wind speed is very good and is greater than 7m/s for 12 hours or more every day, then you can choose a 2kw fan.
As for the battery, it is recommended to choose at least 10 A 12v 150AH battery can basically store 15kw of electricity, which can last for a day without wind. If the number of days that need to be supported increases, you can double the battery.
Although your maximum power does not exceed 600w, It is still recommended that you choose a 2kw inverter, after all, the difference is only a few dollars.
The mechanism of small household wind turbines that can infinitely turn with the wind is usually called a yaw system or rudder. The main function of this mechanism is to allow the wind turbine to automatically adjust the direction of the blades as the wind direction changes to ensure that it always faces the wind direction, thereby maximizing the use of wind energy for power generation. The rudder, usually located at the tail of the generator, accomplishes this function by sensing changes in wind direction and adjusting the direction of the entire body accordingly. This design not only improves power generation efficiency, but also reduces potential damage to the generator caused by changes in wind direction.
