The car central locking motor is a micro drive gear motor. The working principle of the car central lock is to convert electrical energy into mechanical energy. The electric motor drives the gear to turn to open and close the door. It is mainly composed of a door lock switch, door lock actuator and door lock controller. The door lock actuator is controlled by the door lock controller to lock and open the door lock.
There are three kinds of structures: electromagnetic motor, DC motor and permanent magnet motor. The central locking motor is the drive device in the car remote central lock whose main transmission structure is assembled by a driving motor (motor) and planetary gearhead. The driving motor can adopt brush DC motor, BLDC motor, stepper motor and coreless motor as the driving source while the planetary gearhead can adopt satellite gearhead, cylindrical gearhead and worm gearhead as the reducer.
Different types of car central control locks are usually developed with custom technical parameters. ZHAOWEI Machinery & Electronics Co., Ltd provides a set of customized development services. The customized technical parameters provided by ZHAOWEI are shown below:

Project Name: Car Door/Window Lift Motor
Project Description: The automobile window lift motor generally refers to the functions that the window glass can automatically rise and fall, and it is convenient to open/close windows even during driving, so the power car window is also called the automatic car window. Compared with the past, it is now more often used in modern cars. The electric window system is composed of the car window, window glass regulator and motor gearbox, relay, switch and the ECU to complete the lifting function. Each car window will be controlled by a motor in order to rise or fall.
