Does anyone know what electric ball means?

The electric ball is a part of the generator, which refers to the rotor of the generator. The generator is a combination of a group of mechanical parts. The main function of the electric ball (function) The electric ball is the source of power, which mainly has the following three functions. 1 rotor is smaller in diameter, lighter in weight and less inert than traditional magneto magnet steel, which can be exchanged for faster throttle response; Most of them have no power generation function, or the power generation is very small, which can be exchanged for less resistance during operation; The ignition curve of the new electric ball igniter is ideal, which is much better than that of the traditional igniter and can be exchanged for a nearly perfect ignition angle.
