What is the working principle of a motorcycle magneto?

[Raymond]

Motorcycle magneto works by generating a magnetic field after being electrified, then the rotor starts to rotate, the motor drives the wheels, and controlling the speed is essentially controlling the size of the resistance. Overview: The function of a motorcycle magneto is to start the motorcycle. It is a small alternator that uses permanent magnets to generate a magnetic field and serves as the ignition power source in the gasoline engine's ignition system. The magneto ignition system consists of a switch, ignition coil, circuit breaker, capacitor, distributor, and safety discharge device. It generates high-voltage electricity and distributes it to the spark plugs of each cylinder. Others: Most magnetos adopt a rotating magnet type and can be divided into unitary type and flywheel type according to the overall design. The unitary type integrates all the above components into one unit, which is installed on the internal combustion engine. The flywheel type mounts the magnet on the flywheel of the internal combustion engine, with other components installed separately on the engine, mostly used in single-cylinder engines.
