As we all know, the starting of the engine needs the support of external force,carstarterIt is playing this role.The starter can changeAccumulatorThe electric energy is converted into mechanical energy, which drives the flywheel of the engine to rotate to realize the start of the engine.
Generally speaking, the starter uses three components to realize the entire starting process.The DC motor introduces the current from the battery and makes the drive gear of the starter produce mechanical movement; the transmission mechanism meshes the drive gear into the flywheel ring gear, and at the same time it can automatically disconnect after the engine is started; the starter circuit is turned on and off by an electromagneticswitchTo control. Among them, the motor is the main component inside the starter. Its working principle is the energy conversion process based on Ampere's law that we are exposed to in junior high school physics, that is, the force of the energized conductor in the magnetic field. The motor includes the necessary armature, commutator, magnetic pole, brush, bearing and housing and other components.

1. After turning on the start switch, the starter rotates at a high speed and the engineCrankshaftNo reaction.This phenomenon indicates that the fault occurred in the transmission mechanism of the starter, which may be a transmission gear or one-wayclutchCaused by wear and tear.
2. The starter does not work normally and the drive gear does not rotate. There are many reasons for this phenomenon, such as problems with the power cord, ablation of the starter switch contact plate, and excessive engine resistance.
3. The power output of the starter is insufficient to driveCrankshaft. Short-circuit of the excitation coil and loss of battery power can cause insufficient power of the starter.
4. The running sound of the starter is harsh. This may be caused by the blocking of the one-way clutch or improper installation of the starter.
5. There is a "click" sound when the starter is switched on and off, but it does not work. This phenomenon can be caused by keeping the coil disconnected or due to a severe loss of power from the battery.
Maintenance recommendations:
The starter is a valuable part of the car and will not be easily damaged. However, in order to prolong the service life of the starter, proper use is also necessary. In the process of starting the engine, the starter needs to introduce 300~400 Ah of electricity from the battery. Therefore, in order to prevent the battery from over-current or damage, the starting time should not exceed 5 s; in winter, it is easy to start difficult phenomenon, many times Each start time should not be too long when starting, and there should be a proper interval between each start.
