Car Remote Central Locking System Parameters

Publish Time: Author: Site Editor Visit: 107

The car central locking motor is a micro drive gear motor. In order to run, the central locking motor converts electrical energy into mechanical energy. The electric motor makes the gear 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 in order to lock and open the door lock.

There are three kinds of structures: the 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 drive motor and gearbox. The drive motor can use a brushed DC motor, BLDC motor, stepper motor, or coreless motor as the drive source while the gearbox can use planetary gearhead, cylindrical gearhead, or 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 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 function of the window automatically moving up or down, making it convenient to open or close windows even while driving. This is why the power car window is also called the automatic car window. Compared to the past, it is now more commonly 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 rising function. Each car window is controlled by a motor in order to move up or down.
