Electric curtains refer to curtains that are opened or closed remotely through the main controller (car curtains, home decoration curtains, office curtains, conference curtains). In addition to protecting passengers' privacy and realizing one-way perspective, electric curtains are mainly used to insulate heat, block ultraviolet rays, and adjust daylighting. Do China Tubular Motor Suppliers introduce what is the working principle of electric curtains?

1. Core component: motor. The main working principle of electric curtains is to use a motor to drive the curtains to move back and forth along the track or to rotate the blinds through a set of mechanical devices and control the forward and reverse rotation of the motor. The core is the motor. There are many brands and types of motors on the market, but in the end, they are nothing more than two categories: AC motors and DC motors.

2. Curtain switch: In order to realize automatic curtain control, in addition to the curtain motor, a curtain switch (curtain controller) is needed. The wireless curtain switch can directly replace the traditional switch for installation without wiring. The connected AC220V voltage can control the forward and reverse rotation of the AC curtain motor. The terminal "L" is connected to the live wire of the 220V power line; the terminal "N" is connected to the neutral line of the 220V power line; the positive and negative of the DC motor can be connected to control the DC For the forward and reverse rotation of the motor, the terminal "L" at the output terminal is connected to the forward phase of the motor; the terminal "N" at the output terminal is connected to the reverse phase of the motor.
　
3. Motor setting: To adjust the stroke of the motor, the length of the window of the user is different, which adjusts the operating range of the curtain motor on the track (the blinds generally rotate 90 degrees). For the specific adjustment method, please refer to the motor manufacturer Manual. Each curtain switch has a string of individual codes, which is connected to the smart gateway wirelessly, and the gateway connects to the router at home through a wired method. As long as consumers download the smart home APP on their mobile phones, they can remotely control the curtains through their mobile phones.
