Roller shutter is a widely used commercial door, which consists of a movable door panel and a scroll attached to it. The Roller shutter can be controlled manually or automatically by electric motor. This paper will introduce the working principle and control mode of the electric motor of Roller shutter in detail.
1、 Working principle of electric motor for Roller shutter
The working principle of the electric motor for Roller shutter is relatively simple. It is mainly composed of a reel, a motor and a transmission. When the electric motor starts, it will be transmitted to the gearbox, and then through a series of reduction gears, the high-speed rotation of the motor will be converted into low-speed movement of the door panel. There are two control modes for electric motor of Roller shutter: manual control and remote control. Below, we will introduce the specific working principles of these two control methods.
The electric motor of the manual Roller shutter is equipped with a hand crank which can be used to switch the door panel. The working principle of the hand crank is that when you rotate the hand crank to the left, the electric motor will start and open the Roller shutter. When you rotate the hand crank to the right, the electric motor will start in reverse and close the Roller shutter. At this point, the current in the circuit will automatically stop, thus achieving switch control of the door panel.
The remote control Roller shutter electric motor requires a remote controller, which has remote control function. When you press the button on the remote control, the signal will be transmitted to the electric motor to control the opening and closing of the door panel. When the door panel reaches its highest or lowest point, the current in the circuit will stop, thereby controlling the switch of the remote control. In this case, the remote control needs to be restarted in order to open or close the door panel again.
2、 Advantages of Roller shutter electric motor
Automatic control is one of the important advantages of Roller shutter electric motor. By controlling the electric motor, various difficulties and risks in manual operation can be avoided. In addition, for commercial doors, automated control can also improve the service life and performance of the door. Other advantages of the Roller shutter electric motor include:
1. The motor has high torque and can maintain strong thrust under heavy pressure on the door panel.
2. The power of the motor is stable and can maintain efficient performance during long-term use.
3. The electric motor of Roller shutter is designed reliably and is very suitable for the use of commercial doors.
4. The automatic control of the electric motor makes the operation of the door more stable and safe.
Roller shutter electric motor is a very practical commercial door control equipment. Its automatic control can make commercial doors more convenient, fast and safe to use. Through the precise control mechanism, the electric motor of Roller shutter can respond to the user's operation at any time to achieve efficient door control and safety protection. In the design and manufacturing of commercial doors, the automation control of electric motors is gradually becoming an important trend and demand.
