The motor is the main energy source of many mechanical equipment. It converts electric energy into mechanical energy. The revolving door is regarded as a large door equipment, and it is a very safe equipment. How do the motors match? You know, the normal cost of revolving doors is millions or even higher, or even tens of thousands. Do they play a role as a driving force? The following is an introduction to the motor of Jinan induction door. Let's have a look

在電氣自動控制和拖曳系統(tǒng)方面，三四翼旋轉(zhuǎn)門的構(gòu)成是相同的，只是傳感器的數(shù)量不同于電機(jī)功率。

In terms of electrical automatic control and towing system, the composition of three and four wing revolving door is the same, but the number of sensors is different from the motor power.

一般來說，如果普通的三相交流異步電動機(jī)作為牽引單元，相應(yīng)的控制方法基本上是基于變頻調(diào)速和變頻調(diào)速。但是，更優(yōu)選采用速度控制方法。如果使用低速交流力矩電機(jī)作為旋轉(zhuǎn)門的拖曳單元，則速度控制方法采用速度閉環(huán)速度控制。兩種控制控制系統(tǒng)所實現(xiàn)的控制效果基本相同，無論是系統(tǒng)的穩(wěn)定性，抗干擾能力，媲美動態(tài)指標(biāo)。然而，系統(tǒng)對行人的反應(yīng)以及發(fā)生磁碰撞的強(qiáng)度要比前者好得多，因為后者在機(jī)械上非常軟。

Generally speaking, if the ordinary three-phase AC asynchronous motor is used as the traction unit, the corresponding control method is basically based on variable frequency speed regulation and variable frequency speed regulation. However, the speed control method is more preferred. If the low-speed AC torque motor is used as the towing unit of the revolving door, the speed control method adopts speed closed-loop speed control. The control effects achieved by the two control systems are basically the same, both the stability and anti-interference ability of the system are comparable to the dynamic index. However, the response of the system to pedestrian safety and the intensity of magnetic collision are much better than the former, because the latter is very soft mechanically.

隨著自動門電機(jī)還必須選擇噪音更少，穩(wěn)定性高，省力，延長使用壽命的產(chǎn)品。不要選擇使用質(zhì)量差的電機(jī)，以節(jié)省成本，回到長期使用帶來維修麻煩。

With the automatic door motor, we must also choose products with less noise, high stability, labor saving and long service life. Do not choose to use motors with poor quality to save costs and bring maintenance trouble back to long-term use.

兩翼旋轉(zhuǎn)門需要兩個0.25kw的電機(jī)，以保證旋轉(zhuǎn)門的平穩(wěn)運行。其他門型選擇一個0.37kw就可以了，轉(zhuǎn)門時開門傳感器的動作慢慢轉(zhuǎn)動，門動作時，動作提升2秒鐘恢復(fù)正常操作。當(dāng)傳感器移動時，轉(zhuǎn)動門并立即停止轉(zhuǎn)動，當(dāng)動作釋放時，在2秒鐘內(nèi)恢復(fù)正常操作。

Two 0.25kw motors are required for the two wing revolving door to ensure the smooth operation of the revolving door. Select a 0.37kw for other door types. When the door is turned, the action of the door opening sensor rotates slowly. When the door is moved, the action is increased for 2 seconds to restore normal operation. When the sensor moves, turn the door and stop the rotation immediately. When the action is released, return to normal operation within 2 seconds.

需要說明的是，旋轉(zhuǎn)門電機(jī)一般在旋轉(zhuǎn)門的天花板上方，門下很少。根據(jù)旋轉(zhuǎn)門的配置，可能有許多傳感器，空氣開關(guān)，急停按鈕，障礙按鈕等等。

It should be noted that the revolving door motor is generally above the ceiling of the revolving door and rarely below the door. Depending on the configuration of the revolving door, there may be many sensors, air switches, emergency stop buttons, obstacle buttons, etc.
