In general, the starter uses three components to achieve the entire starting process. The motor drives the gears into the flywheel ring gear, and can be automatically disengaged after the engine is started; the circuit is switched on and off by an electromagnetism (magnetism). The motor is connected to the motor by means of an electromagnet Switch to control. In this case,

Among them, the generator is the main part of the starter, and its working principle is that we in the junior high school physics in contact with the law of Ampere's energy conversion process based on the power of the conductor in the magnetic field in the role of force. The motor includes necessary armatures, commutators, poles, brushes, bearings and housings.
