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 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.
