1、 Detailed understanding of internal structure of electric rolling shutter door motor

1.铜线电机：采用全铜芯，硅钢材质动力强劲散热好，寿命长。

1. Copper wire motor: all copper core, silicon steel material, strong power, good heat dissipation, long service life.

2.减噪齿轮：采用高强度精钢加厚齿轮加上特殊螺纹设计有效减少噪音。

2. Noise reduction gear: high strength refined steel gear with special thread design can effectively reduce noise.

3.防雷击，超低故障：改进路线，减少接线，降低故障，有效防止高电流冲击对电机产生危害。

3. Lightning protection, ultra-low fault: improve the route, reduce the wiring, reduce the fault, effectively prevent the damage of high current impact on the motor.

总结：电动机内部安置过热保护器，具有过热保护功能。传动机设计合理，工艺，齿轮不易磨损，经久耐用，运行噪音低，振动小。

Conclusion: overheat protector is installed inside the motor, which has the function of overheat protection. The design of the transmission is reasonable, the technology is advanced, the gear is not easy to wear, durable, low noise and small vibration.

二、我厂产品优势

2、 Advantages of our products

卷帘门由铝合金帘片、铝合金导轨、卷帘门电机及钢管五金件配件组成77铝合金型材帘片双层结构更具牢固性  ;圆弧结构运行更顺畅;表面高温喷涂外表更美观。

The rolling shutter door is composed of aluminum alloy curtain, aluminum alloy guide rail, rolling shutter door motor and steel pipe hardware accessories. The double-layer structure of 77 aluminum alloy profile curtain sheet is more stable; the arc structure is more smooth; the surface high-temperature spraying appearance is more beautiful.

铝合金卷帘门配上卷帘门电机，整个门卷起来之后直径很小，假如2.5米高的门洞，直径只有24CM左右，而彩钢板卷帘门的直径会接近40CM左右，车库的高度由于政策限制，一般都不是很高，所以77铝合金型材卷帘门更适合车库门的安装。铝合金卷帘门的门板与导轨全部为铝合金材质，不会生锈，使用寿命超长，所以77铝合金型材卷帘门更适合卷帘门的安装。

Aluminum alloy rolling shutter door with rolling shutter door motor, the diameter of the whole door after rolling up is very small. If the door opening is 2.5 meters high, the diameter is only about 24cm, while the diameter of color steel rolling shutter door will be close to 40cm. The height of garage is generally not very high due to policy restriction, so 77 aluminum alloy profile rolling shutter door is more suitable for the installation of garage door. The door panel and guide rail of aluminum alloy rolling shutter door are all made of aluminum alloy, which will not rust and has a long service life. Therefore, 77 aluminum alloy rolling shutter door is more suitable for the installation of rolling shutter door.

三、卷帘门的安装方法

3、 Installation method of rolling shutter door

1、先在需要安装的门框框口位置画出线。表明尺寸大小，然后找盈科安盾工作人员设计出合适的卷帘门，这里值得注意的一点是框内高度比门扇的高度要一点点。

1. First draw the line at the position of the door frame to be installed. Indicate the size, and then find Yingke Andun staff to design a suitable rolling shutter door. It is worth noting that the height inside the frame is a little higher than that of the door leaf.

2、先把卷帘门的门框固定，这里要先拆掉门框下部的固定板。注意：洞口两侧地面要预留凹槽，经校正合格后，固定木楔，门框铁脚与预埋铁板件焊牢。用水泥砂浆或强度不低于10MPa 细石混凝土嵌塞牢固即可。

2. First fix the door frame of the rolling shutter door. Here, remove the fixing plate at the bottom of the door frame. Note: grooves shall be reserved on the ground at both sides of the hole. After the correction is qualified, the wooden wedge, the iron foot of the door frame and the embedded iron plate shall be firmly welded. Cement mortar or fine aggregate concrete with strength no less than 10MPa can be used to plug firmly.

3、安装卷帘门扇主体门扇。一定要保证卷帘门与墙体结成整体，封闭性要做好，再粉刷洞口及墙体。粉刷完毕后，门缝应均匀平整，开启卷帘门应该自由轻便，不得有过紧、过松和反弹现象。

3. Install the main door leaf of rolling shutter. We must ensure that the rolling shutter door and the wall form a whole, the sealing should be done well, and then paint the hole and wall. After painting, the door seam should be even and flat, and the rolling shutter door should be free and light to open without over tightening, loosening and rebound.
