The principle of a manual generator is in fact the principle of electromagnetic induction. That is, the coil generates an electromotive force induced in the rotating magnetic field. The basic structural components of an ordinary manual generator are as follows. the stator and the rotor. The stator is usually a permanent magnet, the rotor is a coil.
Under the action of an external force, the coil moves in the magnetic field to cut the magnetic field lines to generate an induced electromotive force. If the internal coil forms a closed loop with the external circuit through the brush, then. a current will form in this circuit!

Is a high power hand crank generator a good thing?
Principles of hand crank generator hand crank generators for primary school students:
The working principle of the hand generator is to use changes in the electromagnetic field to generate current. The motor uses coils as rotor and magnets as stator to form a stable magnetic field. The crank continuously rotates the coil in the magnetic field and cuts the magnetic field, producing electromagnetic induction and generating current. The gear belt speed is relatively large, the coil speed is accelerated by the transmission, and the current is stable. The fan accelerates and decelerates with fan speed.
This generator is a machine that uses the principle of electromagnetic induction. When we turnWe use the handle to turn the generator, the generator converts mechanical energy into electrical energy, thus making the LED lights light up.
Can the manual generator for teaching be touched by hand?
Okay. According to the survey everyone asks, high power hand crank generators are better.
1. The quality of high-power manual generators is very good, with an average lifespan of 4 years.
2. The high-power manual generator can exercise you without going to the gym and can be used for exercising.
Can I buy a Xianyu manual generator?
No. Direct outdoor exposure and accidental contact of students without teacher assistance can have an impact on equipment and the human body. A hand crank generator is a direct current generator powered by a hand crank. It is not much different from an ordinary generatorre to the extent that the coil rotates in a magnetic field, but the power is human power. Human power is 0.1-0.2 horsepower. which is around 73 to 150 watts of power cannot be sustained for a long time. Therefore, the crank generates electricityThe power of the machine will not exceed 100 watts.
It depends on the situation.
First of all, Xianyu is a second-hand trading platform. Basically, there are individual sellers on the platform. The quality, brand and usage level of the generators sold are all different. You must distinguish them when purchasing. Product quality. Secondly, it is better to buy used generators of well-known brands and not low-end brands, because the performance and cylinder materials of low-end brand generators are not very good. . After use or storage, the performancences will be even worse.
