Why does the motorcycle stall when it is grounded? What is the principle? What is the circuit like?
Other parts of the circuit are simpler. There is a voltage regulator and another generator coil to form the power supply, and the others are electrical appliances.
The alternating current generated by the generator is unstable, and the voltage is different because of the engine speed. All electrical appliances need 12 volts to stabilize DC, so this is done by voltage regulator. There are several different voltage regulators, most of which work in the same way, but they have changed a little according to different types of generators.
Let me say that one of the most common and complicated is the JH70 engine. Her generator has two taps, that is, the winding turns are different, and the other end is directly grounded to the car, that is, the yellow wire and the white wire. The yellow line is the headlight line and the white line is the battery charging line. After passing through the regulator, it becomes a DC charging line of 12V. The rectifier here is a half-wave rectifier, that is, a red line is sent to charge the battery and the yellow line is adjusted. After that, it will be changed into regulated 12V alternating current through the voltage stabilizing circuit and directly supplied to the headlights. The black line inside is the ground wire, and the battery wire is connected in parallel with the vehicle power cord.
In another regulator, only two wires are directly connected to the regulator, and both ends of the generator coil are not grounded, which is the most stable voltage and DC. It's just that this regulator is a full-wave rectifier, which converts all the generated electricity into DC, adding a stable voltage line to accurately control the voltage. Headlights also use positive pressure to complete DC supply to batteries. There is also a three-phase alternator that is exactly the same as this opportunity. Needless to say, I believe you still want to know what to ask.
