How does the wind turbine drive the DC motor to produce electricity and how to charge it after conne

Introduction How does the wind turbine drive the DC motor to produce electricity and how to charge it after connecting it to the battery? Even if the wind turbine drives the DC motor to rotate via a suitable method, it will not rotate the DC motor.

How does the wind turbine drive the DC motor to produce electricity and how to charge it after conne

Even if the wind turbine spins the DC motor in a proper method, it will not allow the DC motor to generate electricity normally. This is due to the physical structure of the DC motor. It is designed to accept current and current. has very poor reversibility. Rotating the DC motor rotor can indeed produce output voltage, but the voltage is very small, and the output current is also very small, which is of no practical value if you really need to use a direct current motor to produce electricity. , you need to modify the motor and perform correct energy conversion. This is very problematic.

If a DC motor could also be used directly as a generator, there would not be two products: the DC motor and the DC generator.

If the transformation succeeds, itYou just need to add a regulated power supply to the output and adjust the appropriate output voltage to charge the battery.

For reference only.

Why can wind turbines generate large amounts of electricity if they rotate slowly?

If the wind turbine in the poster does not spin in strong winds, the problem may be:

1 Check if the generator's 3-phase AC line is shorted.

2. If the fan blades are installed upside down

3. If the engine is burned out

4. Bearing problems

The other two fans from the original poster Question:

When a person on the ground doesn't feel any wind but the fan blades are spinning very fast, it's is normal, because of course people on the ground feel that there is no wind, and when the fan reaches several meters in height, the wind direction changes. The main thing is to see if the leaves move. If the leaves are visiblewindy weather, it is normal for the fan to turn like this. slowly, but the other does not turn. What is the distance between the two units? If it is too close, this is normal, because the two units cannot be installed too close to each other, which will affect its overall effect. In addition, the owner knows that there should be no high-rise buildings nearby when installing the fan and it is better to install it in an open space.

Regarding these situations, please check if. the above conditions apply.

The faster a wind turbine spins, the more electricity it generates. Note that the power output of a generator can be roughly thought of as proportional to the product of speed and torque. The torque here is the electromagnetic torque obtained by the excitation of the generator. The torque is so great that the wind cannot move the turbine. At this moment, the speed of rotation is 0, the torque is very large, and the power output is 0. When the torque is zero, the speed accelerates to a very high speed. It's actually a flying car, which is extremely dangerous. Since the electromagnetic torque is 0, the power output is 0. The power is 0 at both extremes, so there is an optimal speed that maximizes the power output.

The ideal value of this optimal speed can be calculated from Baez's theory, which is the ratio between the linear speed of the blade tip and the wind speed in front of the wheel. At a certain wind speed, there is a non-linear relationship between fan power and blade tip speed ratio. Through the theoretical derivation, the optimal peak speed ratio for each wind speed can be calculated. A wind turbine is a device that converts wind energy into mechanical energy.ue, then allows the machines to operate and finally generates alternating current. In fact, wind energy can also be considered solar energy because it is also used to generate electricity and has a great impact on our environment. There is no danger to the environment.

It is capable of producing a large amount of energy due to its internal structure, rather than depending on the external rotation speed of the blade. It's better to spin your own windmill faster. gear inside that turns silently. The windmill rotates at a speed of 20 to 30 times per minute, and the wind is not enough. That doesn't mean it can't spin faster. This is due to the weight and length of the blades. you see it from a distance, don't think it's big, in fact it is. The blade is more than 20 meters long, and the weight can be imagined. If you turn too fast, it mwill be a lot of pressure on the. base. If a generator collapses or its blades break, it could cause an accident and injure nearby residents. If it spins slowly, there will be no such thing. This will ensure that the windmill blades will not be injured, prone to accidents, and will not affect their power generation efficiency. After all, there's a little engine hidden inside! it, even if the strong wind outside turns very slowly. There are reduction gears and gears inside, and its speed will also increase by about fifty times, basically maintaining a speed of about fifteen hundred revolutions per minute.
