Hand generator
There is little difference between a hand-operated generator and an ordinary generator, that is, the coil rotates in the magnetic field, but the power is manpower. People's general power is 0.1 to 0.2 horsepower, which is about 73 to 150 watts. They can't persist for a long time. Therefore, the power of the hand generator will not exceed 100 watts.
The hand-operated generator can be actively used in field operations, field operations, field investigation, rescue operations, natural disasters, survival training, emergency communication, long-term power shortage, tourism, emergency power consumption, etc.
working principle:
The hand-operated generator can be purchased as a finished product or modified with a motor. It can be modified with the motor of household appliances. The motor of household appliances is a single-phase motor with two windings, one for excitation and the other for power generation. Because the two windings are symmetrical, any one can be used. However, since the winding is used for 220V, the excitation voltage should be DC voltage except the DC resistance of the winding, It should be equal to half of the rated current of the motor. When in use, measure the current with an ammeter and adjust the current to ensure sufficient excitation. However, household appliances are used at high speed, and the speed is much higher than that of hand swing, so the use efficiency is very low.
