The principle of electricity generation in clothes, the principle of electricity generation in the h

It is the induced electricity generated by different materials rubbing against each other.

These questions are all questions of living and application, and they are not as direct as those in textbooks.

1 pair, almost all generator stators are electromagnetic, only generators with small special power stator is permanent magnet (magnet), such as the generator used for demonstration in physics class;

2. AC motors are divided into synchronous motors and asynchronous motors, asynchronous motors work at the rated speed with the best efficiency, the speed range is determined by the slip rate range, and generators are also divided into synchronous generators and asynchronous generators.

3. Yes, the magnetic field formed when the coil generates an electric current is opposite to the stator magnetic field, and the two magnetic fields attract each other, so they always try to hinder the rotation of the rotor;

4.There is no generator that doesn't rotate to cut magnetic lines, but there's a very funny class of crystals that create different charges at each end when you squeeze or stretch it. This effect is known as the piezoelectric effect.

The crystal beard that can produce the piezoelectric effect is called a piezoelectric crystal. Crystal (-quartz) is a well-known piezoelectric crystal.

If pressure is applied to the lamella cut on the crystal crystal in a certain direction, then an electric charge will be generated on this lamella. If the sheet is stretched in the opposite direction, an electric charge will also appear on the sheet, but with the opposite sign. The more force you squeeze or stretch, the more charge you will have on the crystal.

If you answer question 4 incorrectly, please let the landlord post the correct answer is to tell me, or send an e-mail to, thank you!

1. The actual generator used is that the rotor is more than the magnetic pole. The coil is only in the stator, anyway, as long as there is relative motion, it can generate electricity, especially for high-power generators, the rotor is the magnetic pole. Because the current of excitation is much smaller than the current of the electricity emitted, the current through the brush must of course be smaller, and if it is a permanent magnet, even the brush will be saved.

The advantage of permanent magnets is that they do not consume energy to excite. However, the strength of the magnetic field is not high and the strength of the magnetic field cannot be adjusted, so permanent magnets are only used in low-power generators, and electromagnetic ones are used in high-power generators.

2. I'm sorry, but I even learn mechanical, although I have to learn the motor part. But it's not as deep as those who specialize in motors, I don't know.

3. When there is a current in the coil, the resistance torque acting on the rotor will be much greater than that of no load. No load is just frictional moment, but the current in the coil means that there is energy conversion, and mechanical energy is converted into electrical energy. The work done by the additional moment is used to convert into electrical energy.

The principle is that energized wires will be affected by force in the magnetic field, and the motor works on this principle, and the rotor of the generator is also affected by this force.

4. In theory, but it is still in theory, it is a generator that uses the regular movement of ionized plasma in the magnetic field to generate electricity, but it is still in theory, and the reality of side-by-side collision has not appeared. The nuclear power generation on the first floor still converts nuclear energy into heat energy and drives the generator through a gas turbine, which is different from thermal power stations except that the energy of coal or oil combustion is used to heat water, and nuclear energy is used to heat water. There are also only batteries, which cannot be said to be resistant to motors, like solar cells, which have practical applications and home power supply, but the efficiency of solar cells is currently very low.

20% is already very high, and this is extremely expensive, only for satellites. There are also fuel cells, which are basically still in the laboratory stage, and have not yet reached large-scale development.

There are traditional rotary motors, plasma generators, so that the plasma passes through the magnetic field, because the Lorentz force is a plasma with different polarity to produce an offset, fly to different plates, so that the plates have a charge, so that the electricity is generated. The essence of a generator is a device that converts other energy into electrical energy. Rotating motors convert kinetic energy into electricity, and solar cells can also be regarded as generators.

Thermocouples can turn the temperature difference into electrical energy, which is heat into electricity. There are also electric eels that can turn biological energy into electricity, which can also be regarded as a generator.

Is there a generator that doesn't rotate to cut magnetic lines?

Yes, nuclear power generation.

I'm dizzy, I'm not good at electricity, mechanics is okay.

Fourth, generators use magnetism to generate electricity, and this nuclear method is very common.

However, have you ever thought about changing the source of frictional electricity to use it to generate electricity?

Is there a generator that doesn't rotate to cut magnetic lines?

Solar power generation.

Other structural components.

The rotor is composed of rotor core (or magnetic pole, magnetic choke) winding, guard ring, central ring, slip ring, fan and rotating shaft.

The stator and rotor of the generator are connected and assembled by the bearing and the end cover, so that the rotor can rotate in the stator and do the movement of cutting magnetic field lines, so as to generate an induced electric potential, which is drawn out through the terminal and connected to the circuit, and the current is generated.

Main classifications: Check out **[Power Generation.]

A windmill is a power machine that converts wind energy into electrical energy. Broadly speaking, it is a thermal energy generator that uses the sun as the heat source and the atmosphere as the working medium. Wind power generation uses natural energy, which is much better than diesel power generation, but it is still inferior to diesel generators if it is used in an emergency.

Wind power is not considered a backup power source, but it can be used for a long time.

Wind power generation is based on the principle of using wind power to drive the blades of a windmill to rotate, and then increasing the speed through a speed-increasing machine to drive a generator to generate electricity (Figure 10-1). According to current windmill technology, it is about 3 ms of light wind speed (2-3 wind speed) to start generating electricity.

Wind power is becoming a boom in the world because it has no fuel problems and does not produce radiation or air pollution.

Wind power is popular in countries like Finland, Denmark, etc.; China is also vigorously advocating it in the western region. A small wind power system is very efficient, but it is not composed of only one generator head, but a small system with a certain technological content: wind turbine charger digital inverter.

A wind turbine consists of a nose, a rotating body, a tail, and blades (Figure 10-2). Each part is important, and the functions of each part are: the blades are used to receive wind power and convert it into electrical energy through the head of the machine; The tail fin keeps the blades facing the direction of the incoming wind for maximum wind energy; The rotating body can make the nose rotate flexibly to achieve the function of adjusting the direction of the tail; The rotor of the machine head is a permanent magnet, and the stator windings cut the magnetic field lines to generate electricity.

Since the blade speed is usually lower than the normal speed of the generator, most wind turbines have a speed-increasing gear gearbox.

Due to the instability of the natural wind speed, the wind turbine will inevitably fluctuate in voltage and frequency, so its output is 13 25V alternating current, which must be rectified by the charger and then charged to the battery, so that the electric energy generated by the wind turbine becomes chemical energy. Then use an inverter with a protection circuit to convert the chemical energy in the battery into AC 220V AC power to ensure stable use.

Mechanical connection and power transmission, the horizontal axis fan blade is connected with the universal elastic coupling through the gearbox and its high-speed shaft, and the torque is transmitted to the generator shaft, which should have the characteristics of absorbing damping and vibration very well, which is manifested as absorbing an appropriate amount of radial, axial and a certain angle of offset, and the coupling can prevent the overload of the mechanical device; The other is a direct-drive fan, and the blades are directly connected to the motor.

On December 11, the Fukui Prefecture Industrial Technology Center in Central Japan launched a piece of fabric woven from extremely thin small spherical solar cells that can be made into clothing such as tops or trousers to power the electronic devices it carries.

The new fabric, which is made up of extremely thin solar cells intertwined together, can be sewn into tops or trousers to power the mobile ** and other electronic devices they carry when necessary, according to the researchers. Clothes made from this special fabric literally brighten up our lives, and the solar-powered fabric finally allows the wearer to reap the energy as they walk around.

However, its inventor admits that there is still a lot of work to be done before the fabric can be put on the market. A member of the technical center said: "We still have some issues to be solved before commercialization, such as coating the conductive wire and improving the durability of this fabric. ”

The head of the center said that now we have been in contact with some electronics manufacturers, and they are very interested in the invention. However, in the future, the development and production of new fabrics will be carried out in cooperation with solar cell manufacturers and other private companies based on the Kyoto Protocol.

It can generate electricity...

Polyester fabrics are prone to static electricity and cause them to stick when worn**.

South Korea has developed a new energy harvesting system that collects energy when we move. We only need to attach the system to clothes, windows, building facades, and it can generate electricity.

In the future, wearing solar heat conduction generators will become popular and become a must-have item in the wardrobe. Generators can provide power to a variety of devices, such as smartphones and smart glasses, and the energy comes from heat, light, sound, vibration, and movement. New technologies have made breakthroughs in generating electricity more efficiently, and new technologies have improved efficiency by widening the temperature difference.

Kyoung Jin Choi, a professor at the School of Materials Science and Engineering at the National Institute of Science and Technology in Ulsan, South Korea, led a team that developed a device that harvests electricity based on temperature changes (converted between hot and cold). With new technology, the temperature difference can widen up to Celsius. Wearable heat transfer generators have also appeared before, but the temperature difference is generally between up to 10 degrees Celsius.

The generator converts the heat flow (that is, the temperature difference) into electricity, through the so-called"The Seebeck effect"Invert. Power plants are also considering large-scale collapse of such generators to convert wasted heat into electricity.

To improve the efficiency of the generator, the professor attached a local solar absorber to the substrate. The solar absorber is a 5-period Ti MGF2 supercrystalline lattice with 5 layers, which can absorb a large number of more solar energy. In this way, the temperature difference will expand, and it can provide enough power to wear the stupid round electronic device.

It is the static electricity generated by the friction of the clothes on your body, especially in a dry environment, it is very easy to produce static electricity, such as when the spring and autumn are dry, sometimes when you close the taxi door, there will be a "pop" discharge sound on your fingers and the car door, as for you go to the toilet and run out of electricity, it is because the toilet is damp, and you have finished putting it with your classmates.

Wearing chemical fibers, sweaters and other clothes on the body is easy to rub and cause electricity, and this situation occurs when it touches people or metal.
