The armature is the key component of the starter motor, like the heart of the starter motor. It is composed of a steel shaft, a steel laminated core, copper windings, and a copper-segment commutator. The function of the armature is to convert electrical energy into mechanical energy, and to drive the start of the internal combustion engine through the motor output system.

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.

The alternator is the only charging component of the battery on the vehicle, and it is also the power provider for all electrical system on the vehicle. The alternator is powered by the engine and it is responsible for converting mechanical energy into electrical energy. The alternator is composed of rotor, stator assembly, brush holder, and voltage regulator. The quality of the alternator is related to the safety and operation of the vehicle.

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.
