What is the working principle of electric sliding door motor? How to choose automatic sliding door motor?

The automatic sliding door motor is mainly used to open and close the sliding door. Its internal integration technology is fundamentally different from ordinary motors. There are many products on the sliding door motor market, but the quality is uneven, so it is inevitable that some people will pass it off as good. If users lack relevant knowledge, it will be difficult to judge the quality of the automatic induction door opener. When purchasing an automatic sliding door motor, you should consider the motor\’s horsepower, waterproof performance, and lifespan. You should also understand the door operator type and compatibility. Let\’s learn more about it below.

What is the working principle of the sliding door motor

The principle of the sliding door motor is that the motor drives the belt to rotate, and the belt is connected to the glass hanging clamp to achieve translation. It cannot automatically stop in the middle and can only be operated by the remote control, because this kind of motor generally has a repeated command restriction function: that is, when each opening and closing reaches the position, if the previous opening and closing control action continues to be repeated, the command will not It works to prevent the door from continuing to run in the same direction after exceeding the limit due to inertia and causing damage. The electricity used depends on your motor, which can be single-phase or three-phase. You can find out by opening the control box and seeing what power source is connected. The entire motor system includes motor power devices, and some also have safety devices, such as infrared rays.

How to choose an automatic sliding door motor

Automatic sliding door motors seem to be designed to realize automatic opening and closing, but its internal integrated technology There are fundamental differences. Moreover, our country currently has no industry standards in this regard. Therefore, it is inevitable that some people will pass off inferior products and users lack relevant knowledge.It is difficult to judge whether the automatic sensor door opener is good or bad. What issues should you pay attention to when purchasing automatic sliding door motors? Here are some key points:

1. Look at the motor horsepower. That is, what people usually ask is, how big or how many doors can this door open? People\’s habit is always to simply think that the bigger the door opener, the stronger it will be. This is unscientific. In fact, the power of the motor is determined by the rotor parameters (diameter, stack thickness) and the motor magnetic tiles.

2. Check the waterproof performance of the motor. The waterproof performance of the motor is determined by the outlet and bottom cover sealing rings. Comparing high-quality sliding door motors with imitations on the market, it is easy to find that the outlet of high-quality and big-brand sliding door motors is fully sealed and undergoes special waterproofing treatment, and the bottom cover sealing ring is made of oil-resistant rubber. Seals.

3. Check the life of the motor. The materials and manufacturing processes used for the motor\’s worm gear, bushing, reducer volute, rotor support structure, mounting base and other components determine the motor\’s service life and its ability to withstand bumps and impacts.

4. When choosing the type of automatic door machine, if the flow of people is small, the door opening is average, and the investment budget is small, such as an office or writing room, you can choose an ordinary door machine with a low price. Low door operator. This type of door operator can generally be used without problems, but its service life will be relatively short. If the purchaser has good after-sales service and can provide on-site repair services at any time, then you can use it with confidence.

5. Pay attention to the compatibility of the automatic door motor. The door operator is required to be compatible and be able to install these devices. Some automatic door operators have such functions themselves and are easy to install. However, some door operators do not have this function and must be equipped with many additional devices to install them, which leads to unnecessary expenses.
