Does Tubular Motor Manufacturer introduce what is the electric door closer motor?

Electric door closers are also called automatic door closer releases, electric releases, etc. It is a mechanism that realizes the automatic closing of the door leaf through electric control. Electric door closers are different from hydraulic fire-proof door closers. They combine the functions of an electromagnetic release and an unclosed.

There are solenoid valves and powerful springs inside. The springs are compressed when the door is pushed and locked by the solenoid valve to keep the door in a normally open state. When power is supplied, the solenoid valve is released and closed by the rebound impact of the spring, without buffer function. It was first applied to normally open fire doors. Later, due to the fire department’s belief that the closed doors did not comply with fire protection regulations, they were not promoted and applied in the fire door market. At present, hydraulic automatic door closers are still used in the fire door market.


Roller Shutter Tubular Motor Manufacturers introduces the relevant knowledge of brushless DC motors and DC motors:

1. The brushless DC motor has good linearity of mechanical characteristics and adjustment characteristics, wide speed range, long life, easy maintenance, low noise, and no series of problems caused by brushes, so this kind of motor is in the control system There are great applications.

2. DC motors have the advantages of good speed regulation performance, easy starting, and load-start ability. Therefore, DC motors are still widely used, especially after the appearance of SCR DC power supplies.


Roller Shutter Tubular Motor Manufacturer introduces the difference between electric and smart curtains:

Electric curtains can be divided into built-in type and external type in terms of installation. Electric curtains are divided into electric opening and closing curtain series, electric lifting curtain series, electric ceiling curtain (outdoor electric canopy and indoor electric ceiling), electric sun visor, electric awning, etc. according to the different operating mechanism and decorative effect, such as blinds Blinds, roller blinds, Roman blinds, soft gauze blinds, organ blinds, honeycomb blinds, etc.

Smart curtains are electric curtains with certain self-reaction, adjustment and control functions. For example, it can automatically adjust the light intensity, air humidity, and balance room temperature according to the indoor environment. It has three outstanding features: intelligent light control, intelligent rain control, and intelligent wind control.

For customers, both curtains can be operated by remote control. According to the author’s installation experience, the electric curtains mainly use infrared remote control, wireless remote control, etc. to realize the operation, including some remote control set in the window head. The smart curtain adds a WIFI module, and the wireless module can be used to operate the curtain through the mobile phone, no matter where you are, you can use the mobile phone to operate. Early electric curtains could only be controlled by a switch panel on the wall or an infrared remote control. The switch had to be connected to a wire, and the remote control had to be aimed at the motor. This kind of curtain only saves the effort of pulling the curtain manually, but it still can’t make people too lazy.

Through the above introduction, Radio Tubular Motor Manufacturers hopes that you can simply refer to the content of this article in future use.


Tubular Motor Manufacturer introduces seven suggestions for matching electric curtains

1. Space color matching shall not exceed three kinds.

2. Gold and silver can match any color.

3. Do not use warm colors in kitchen curtains, except for yellow colors.

4. The best color matching gray scale of electric curtains for household use is: light wall, middle ground and deep furniture.

5. If the space is not closed, the curtains must use the same color scheme. Different enclosed spaces can use different color schemes.

6. If you want a bright and modern home taste, don’t choose curtains with big flowers and small flowers (except plants), try to use plain designs.

7. The color of the ceiling must be lighter than or the same color as the wall. When the wall color is a dark design, the ceiling must be a light color. The color of the ceiling can only be white or the same color as the wall.


Under normal use, use Tubular Motor running times and hours to measure. The higher the frequency in use, the earlier it will break.

The service life of a Tubular Motor depends on many components, the main content is the circuit part, coils, capacitors, resistors, etc., it will burn if the current is large, and it will burn after normal use. Rotating mechanisms, gears, especially plastic and nylon gears are easy to break. The iron gear is better.

Abnormal noise can be divided into the excessive current. It may be caused by increased friction of the entire mechanism, stuck, and a large current is required, or it may have poor contact and spark operation. Abnormal sound of mechanical collision and friction. It may be that there is a lack of lubricating oil or the positions of the mechanical structures are not accurate and collide with each other.

Through the above introduction, Radio Tubular Motor Manufacturers hopes that you can simply refer to the content of this article in future use.


Electric roller shutter is an electric roller shutter mechanism powered by roller blinds motor. Its operation only needs to flip the power switch, easy to operate, quiet and stable, and it is an upgraded product of manual roller blinds.

So, how does the roller blinds motor work? Let’s take a look together next.

The roller blind motor is hidden in the roller tube, and the drive shaft is rotated by the motor rotation to realize the lifting of the roller blind sheet. When it rises, the blind sheet is wound on the reel, and when it is lowered, the blind sheet slides down along the inner side of the guide rail. Through the control of the remote control, the curtain can be raised, stopped, and lowered.

The tubular motor is composed of a tubular casing, a drive assembly, a brake assembly, and a stroke control assembly supported in the tubular casing through a bearing seat. It has the advantages of the small occupied area, low energy consumption and quick start -up, is a high-performance product.

Tubular Motor can used for awnings, rolling shutters, electric blinds, shades, motorized screens, curtains, projection screens and roll-up application.

Next, let us understand the working principle of the tubular motor. The stroke part of the tubular motor controls the upper and lower limits of the motor; the motor part is responsible for the operation of the motor; the deceleration part mostly uses planetary deceleration to reduce the motor speed and increase the output torque.
