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.
How powerful is the military hand crank generator? Can it reach 100 watts?
Principle of hand crank generator for primary school students:
Hand crank generator generates electricity. The working principle of the machine 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 et 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 turn the handle to turn the generator, the generator converts mechanical energy into electrical energy, thus making the LED lights light up.
The output power of general military hand-cranked generators is about 30-60W. But shaking is more laborious, so you'd better really have the physique of a soldier!
There are some for civil use with lower power, mainly 15 to 40 W. Civilian crank motors have larger gear ratios and lighter jerks, but the lifespan of their gears and the materials of their circuits are inflarger than those of the military, so their height and weight are also smaller.
