As we all know; the engine start demand external force support; the car starter is playing this character. The starter can convert the battery's electrical energy into mechanical energy; drive the engine flywheel to complete the engine start.
The starter layout is generally described; the starter uses three components to complete the entire starting process. The DC motor introduces current from the battery and mechanically moves the drive gear of the starter, and the drive train engages the drive gear into the flywheel ring gear; Together, the engine can be actively disengaged after the engine is started. The on/off of the starter circuit is controlled by an electromagnetic switch. In the meantime, the motor is the primary component inside the starter; its working principle is that we touched it in junior high school physics. The ampere law is the transformation process of the energy at the base; that is, the effect of the energized conductor in the magnetic field. The motor contains the necessary armature, commutator, magnetic pole, brush, bearing and casing.
Common appearance of starter and generator assembly:
â–  1. After the start switch is turned on; the starter rotates at a high speed and the engine crankshaft does not reverberate. This appearance indicates that the fault occurred on the transmission structure of the starter; this may be caused by the wear of the transmission gear or the one-way clutch.
â–  2. The starter does not work properly; the drive gear does not rotate. There are many reasons for this appearance; for example, the power cord presents a problem, the start switch touch panel ablate, and the engine resistance is too large.
â–  3. The lack of power output of the starter; unable to move the crankshaft. The short circuit of the excitation coil and the loss of the battery can cause the lack of power of the starter.
â–  4. The starter operation sounds sharp. This may be caused by a one-way clutch jam or a starter device.
â–  5. There is a "beep" sound when the starter switch is turned on; but it does not work. Insisting the coil disconnection or the battery is severely depleted will cause this appearance.
Protection claims:
The starter is attributed to the valuable parts of the car; it is simple and will not be damaged; however, in order to extend the service life of the starter; proper use is also necessary. The starter is in the process of starting the engine; it is necessary to introduce 300~400 Ah from the battery; Therefore, in order to avoid the appearance of over-current or damage to the battery; the starting time should not exceed 5 s, and the winter is simply a difficult starting phenomenon; the starting time should not be too long when repeatedly starting; the appropriate distance should be left in each starting.
