1. Go to the electronics market and buy a small model airplane motor. It is a DC motor with a built-in permanent magnet and powered by a rechargeable battery or storage battery. The motor shaft should be slightly longer.
2. Make your own windmill. The windmill shaft should be made of plastic or wood and glued to the motor shaft to ensure that there will be no slippage between the motor shaft and the windmill shaft when the windmill turns. .
3. The two terminals of the motor wiring are connected to the small lamp beads. You can see that when the fan rotates, the lamp beads glow slightly.
If you want a bigger one, one needs a bigger motor, preferably with a brush and collector, and the other needs a strong enough windmill to resist greater wind force and drive the shaftu engine. Making a wind turbine with a dual-powered motor requires two power systems for the rotor and stator, which is quite complicated and is not recommended.
The working principle is that the operation of the DC motor generator and motor is reversible, especially after the permanent magnet is integrated into the stator, no special excitation winding is required. is required, which can greatly simplify the design. .
The tricycle motor fan blades are noisy
Just use an electric fan to modify it. Use a household electric fan motor with a power of around 50W and pair it with an industrial electric motor. fan blade (the power is about 2~300W), and the effect is good when making a wind turbine.
The bracket needs to be made by self, which can rotate, then the rear fin for navigatingation. is done, and everything is settled. The connection cable is longer, although you only need to wrap the bracket more than 10 times without breaking it. However, you have to unwind the tangled wires every day, but you can keep the electrical slip ring. . The technology is relatively simple.
The output end and capacitor are attached to help create voltage, and install a low power overcurrent switch or fuse to prevent the generator from overloading< /p>
Tel. a generator also has disadvantages, that is, the frequency changes with the output power, the voltage fluctuation is also relatively large, and it is easy to burn the bulb, can be used for rectification and charge, the lamp will need to be converted. to DC, and the price will be much more expensive.
Network-connected operation can solve such problems, but it will also cause againx problems. When the wind power is insufficient, the wind turbine turns into an electric fan and it is easy to burn the motor. is better to cut off the start capacitor or It is also possible to change the direction and install the fan blades in another direction, but low winds will still consume some power. Installing a power relay can solve the power backflow problem, but the price of the system will increase and the gain will exceed the loss.
Note that the generator made this way does not have overspeed protection and will be more dangerous on windy days.
The noise from the tricycle motor fan blades is caused by the damaged and unrounded bearing.
When the electric tricycle is turned on, you will hear a whistling sound from the motor. As the name suggests, this should be an engine problem. Sometimes this may be called a noisestrong. It is caused by tightening. correspondence between the helical teeth of the motor and the transmission gear, or the gap if it is too large, replace the motor.
If there is wind noise from the motor fan blades rotating, open the fan cover and check if the fan blades still make noise after being removed.
Gearbox and differential problems, the internal gear gap is too large, the only option is to replace the differential or replace the differential transmission gear.
