What are the five electrical parts of a motorcycle?

Relay

Motor starter relay is actually an electromagnet, through the start button and other starting circuit to generate electromagnetic force, so that the relay two contact head connected together, turn on the battery and start the motor, the battery to the starter motor to drive the engine rotation , Complete the electrical start process. When the release button, the relay current disappears, there is no electromagnetic force, the relay will disconnect the battery and start the motor connection, return to normal driving state.

Ignition coil

Ignition coil is mainly composed of a coil, secondary coil and iron core, in fact, is a transformer. The core is made of dozens of pieces of steel or steel wire. The secondary coil is made of copper wire (0.1mm) copper wire on the core around 10,000 turns, one end of which is connected to the capacitor (high voltage terminal ), The other end connected to a coil; a coil is wrapped in a second layer of thick insulation paper, and then around the hundreds of turns around 0.5-1.0mm copper wire. It works by the igniter to a coil power supply, in a coil from the induction of the voltage of 200-300 volts, it and the secondary coil mutual inductance and produce 10000-20000V high voltage, the resulting voltage depends on the size The turns ratio in the two coils, and then the high voltage electricity to the spark plug ignition. Popular that he is a transformer, an input voltage of more than 100 volts, the second output of more than 10,000 volts for spark plugs flash.

Igniter flame lighter

The role of the igniter is to receive and store the magnetic motor to provide the ignition voltage, and accurately calculate the ignition time, timely supply to the high-pressure package, high-pressure package will be low-voltage igniter of high-voltage electric spark plug ignition.

Pressure regulator

Motorcycles in the idle and normal driving, the engine speed range is very large. Correspondingly, the generator output voltage change will be great. Generally vary between 15V and 60V. This unstable voltage can not be directly on the battery and light bulbs and other electrical power supply. At this time, we must use the regulator. The regulator can output a relatively stable voltage of 13V-14V at 15V-60V. So, this voltage can be connected to the battery

There are two kinds of voltage regulator work, one is short-circuit, the other is chopped. The short circuit structure is simple, but the power consumption is great. Because after the input voltage goes high, the excess energy has to be released in a short circuit. There is no short circuit now. Another kind of chopper, because the generator is issued by the AC, so you can use the power thyristor on the alternating current chopping, that is, through the circuit to trigger the thyristor delay. The longer the delay, the lower the effective voltage output. In this way, through a feedback circuit automatically control the length of the delay time, you can control the output voltage. This regulator although the circuit is complex, but because of low power consumption, high efficiency. So now widely used.

Flasher

The main role is to turn the rhythm of the lights flashing. Most flashers now come with buzzers.
