Energy conservation, under ideal conditions the output power of the generator is the rated power of the electric vehicle motor, such as 350W... But in reality it is absolutely not feasible to use wind power as the energy supply for electric vehicles, because you not only need to use air The kinetic energy of the car is converted into the kinetic energy of the car, and part of the energy is also converted into the internal energy generated by the friction when the car is running, which is heat, and the energy lost by the friction of each moving part, so the power of the wind turbine is greater than that of the electric car The power of the motor...even using a sail is better than this! I think you may think that the battery capacity is small and you want to increase the mileage. I thought about using solar energy, but the panel area is too large and is only suitable for covered tricycles. There is not enough room for bicycles. Let me give you two suggestions! Install a lithium battery, which is very light, either polymer or lithium iron phosphate. Then you can get a two-stroke gasoline alternator with a power of less than 500 watts, or simply build a DC generator set with the same voltage as an electric car. , but the noise is louder...
How to make your own wind energy generator!
Zhong Yan’s idea first came from a business trip he took while driving in the autumn of 2008. At that time, he was driving along the Beijing-Shanghai Expressway towards Shandong. He noticed that where the car passed, the leaves of the green belt on the highway began to shake significantly. Zhong Yan had a sudden thought: Since natural wind can be used to generate electricity, why can't this artificial wind be used?
After returning to Beijing, he told several technicians about his ideas. After several discussions, they found that capturing the wind in subway tunnels was an ideal choice. Although there are tunnels on highways and ordinary railways, these tunnels are short in length and are not conducive to the collection of wind energy. Subway tunnels are closed underground and have a long mileage, making them the best tunnel system for collecting wind energy.
Zhong Yan believes that as long as suitable fans are installed on both sides of the tunnel walls of the subway tunnel, electricity can be generated, and this electric energy will be transmitted to the subway platform through transmission, energy storage, grid connection and other links. This can solve the problem of electricity consumption for lighting and billboards in subway stations.
Is a closed generator better than an open radiator
1. Go to the electronics market and buy a small motor for model aircraft, which has a built-in permanent magnet and can be charged The DC motor powered by batteries or accumulators has a slightly longer motor shaft.
2. Make your own windmill. The windmill shaft should be made of plastic or wood and bonded with the motor shaft to ensure that there will be no slippage between the motor shaft and the windmill shaft when the windmill rotates.
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 will glow slightly.
If you want a larger one, one needs a larger motor, preferably with a brush and commutator, and the other needs a windmill strong enough to withstand greater wind force and drive the motor shaft. Making a wind turbine using a doubly-fed motor requires two power supply systems for the rotor and stator, which is complicated and not recommended.
The operating principle is that the operation of the generator and motor of the DC motor is reversible. Especially after the stator has built-in permanent magnets, no need forA dedicated excitation winding is required, which can greatly simplify the design.
Okay.
1. A closed generator refers to a generator that is sealed inside and usually equipped with a cooling system on the outside to reduce the temperature through air or liquid circulation to prevent failure caused by overheating.
2. An open radiator refers to a radiator without a cover. It uses natural air cooling or forced air cooling to dissipate heat through the air to the heat exchange tubes on the surface of the heat exchanger to reduce the operating temperature. .
