Automobile central door lock actuator is an important electronic and mechanical assembly that implements centralized control of the locking and opening of the door for convenience and safety.
The working principle is that after receiving the locking or unlocking instruction from the central controller, the micro-motor is driven by electric energy to control the locking or unlocking of the door, so that the door can be opened with the inner or the outer handle.

The starter is a key component that guides the internal combustion engine from a static state to an automatic working state. The relationship between them is like a match and a candle. The starter is composed of a DC motor, a control system, and an output system. The pros and cons of the starter will affect the speed requirements of the internal combustion engine from a standstill to its automatic operation.
