It's a bit superficial for high school students to do that. . This is something done by elementary school students. . . Unless you have really innovative ideas.
Let me give you some advice.
1. The rotor must be balanced. If you make it yourself, you must use silicon steel sheets. It is recommended to buy a motor, which costs only about ten yuan. If you really want to make it yourself, you must first buy one and take it apart to study it.
2. Do not use alternating current. Two poles are enough to make a small electric bead shine.
3. If you throw it by hand, use a gear to change the speed. Otherwise, even if you shake your hand, it won't have much effect.
I wish you luck
Urgent! If you understand the problem of wind turbines for residential buildings, please give us some advice.
It's not that simpleThe generators provided cannot be connected to the grid. It's just that the equipment and procedures connected to the network are complicated, and it is not cost-effective for a small unit.
It is recommended not to connect to the network. Since it is a rural villa, it doesn't matter if the power is out for a period of time, it may be "power outage and back-up". "Supply", that is, the main use is generator energy, and the grid energy is used after the power outage. , wouldn't it be good to have a "nine-wire gate" command?
If you need to connect directly to the grid, there is a photovoltaic inverter produced by the German company SMA that can solve this problem. A grid-connected solar photovoltaic power plant uses photovoltaic modules to convert solar energy into direct current, then reverses the direct current into coualternating current of 50 Hz, 230/400 volts three-phase or 230 V single-phase via an inverter. The output end of the inverter is connected in parallel with the low voltage end (230/400 volts) of the transformer in the substation via the electrical distribution cabinet to supply the load, and the excess power is sent to the network via the transformer. There is no battery energy storage equipment overall. When there is no sun on rainy days, electricity is supplied to the load from the grid.
The most commonly used household fan models are 1 KW, 2 KW, 3 KW and 5 KW. The specific choice of power depends on the household appliances used in charging, their power and number. hours per day they are used. For example, if you have a 1 horsepower air conditioner that runs 8 hours a day, a television, a washing machine, and a rice cooker, a c3 kW air conditioner will be enough.
Home wind turbines are generally small and medium-sized wind turbines. In small and medium-sized wind power plants, relevant people revealed that the product quality of Qingdao Hengfeng Wind Turbine Co., Ltd. GOOD. You can check online and contact them.
According to information, the price of wind power raw materials has increased significantly, and almost all manufacturers have increased their prices. If there is truly a need to buy, you should seize the time and buy before prices increase.
