The reason for the low voltage after converting the small motor into wind power generation is the influence of resistance or inductance in the circuit. After the small motor is converted to wind power, its output voltage will also change. In the circuit, the influence of components such as resistors or inductors on the voltage cannot be ignored. The parameters of these components in the circuit are not adapted to the new output voltage, resulting in a low output voltage.
I would like to ask how to use wind to light a small flashlight bulb
1 Go to the electronics market and buy a small motor for model airplane , who 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 must be in pelastic or wooden 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 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 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 motor shaft. 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 generator and the motor of the DC motor is reversible, especially after the integration of the permanent magnet dIn the stator, no special excitation winding is required, which can greatly simplify the design. .
Can a toy racing car's engine produce electricity?
It's actually very simple, the materials are easy to buy
I don't know how to explain the principle of energy production in physics, but I tried wind power generation with small light bulbs when I was a child
Materials, a four-wheel drive motor (the more common the better), a plastic or wooden airplane propeller (the blade area is as large as possible and the blades are as numerous and dense as possible), and a variable speed gear train which is also a model airplane, make it yourself. It's also very simple
I made the structure myself with wood shavings and latex glue which I mainly used. large, lightweight propellers with largewind surfaces which are easily blown and enlarged gears behind the propellers (also for four-wheel drive vehicles), then connect the motor of the four-wheel drive car, then use 2 wires to connect. the electric chip from the motor to the small light bulb, and that's it.
Haha, the racing car motor can usually generate electricity in two parts: which I don't understand, there are some. There are magnets in the outer casing of the stator and copper coils on the rotor of the motor core. The stator magnets produce magnetic lines of force. When the rotor turns, the copper coil above it also turns, which can cut the magnetic field lines emitted by the magnet on the stator, so that electrons flow through the copper wires. It will generate electric current, so you can produce electricity
