What is the Principle of a Four-Wire Motorcycle Rectifier?
1 Answers
The principle of a four-wire motorcycle rectifier: The rectifier, also known as a voltage regulator, converts AC voltage into DC voltage. Voltage stabilization involves maintaining the unstable voltage output from the generator within a specified range. The device that achieves these two functions is called a rectifier-voltage regulator. The four-wire rectifier includes four wires: green, pink, yellow, and red. The green wire is the ground and is directly connected to the chassis; the pink wire is the AC input, connected to the generator's AC line; the yellow or white wire is the other AC input, connected to the other end of the generator's AC output; the red wire is the output positive terminal after rectification and voltage stabilization, used to connect to the positive terminal of the battery. The rectifier is a very important electrical component on a motorcycle. Its functions are twofold: first, to provide a stable working voltage for the motorcycle's electrical equipment, and second, to divert excess current to protect the electrical devices. It converts the AC electricity generated by the magneto into DC electricity, while reducing the higher voltage to a suitable level to charge the battery. Additionally, it dissipates excess electricity through resistors to achieve voltage stabilization. Once the generator fully charges the battery, it automatically shuts off and stops working. This means the engine does not need to waste fuel overcoming magnetic torque. Therefore, the four-wire chopper type is more fuel-efficient.
