The working principle of the motor is that the rotor of the starter rotates by the force of the energized coil in the magnetic field, and the pinion on the rotor drives the flywheel of the engine to rotate. The electronic starter is the motor that people usually refer to now, also known as the starter. It is rotated by the energized coil in the magnetic field to drive the rotor of the starter to rotate. The pinion on the rotor drives the flywheel of the engine to rotate, thereby driving the crankshaft to rotate. The innovation of two new low-cost spark plugs and starters with a ceramic core base has laid the technical foundation for the development of the car.
