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

在电气自动控制和拖曳系统方面，三四翼旋转门的构成是相同的，只是传感器的数量不同于电机功率。

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.

一般来说，如果普通的三相交流异步电动机作为牵引单元，相应的控制方法基本上是基于变频调速和变频调速。但是，更优选采用速度控制方法。如果使用低速交流力矩电机作为旋转门的拖曳单元，则速度控制方法采用速度闭环速度控制。两种控制控制系统所实现的控制效果基本相同，无论是系统的稳定性，抗干扰能力，媲美动态指标。然而，系统对行人的反应以及发生磁碰撞的强度要比前者好得多，因为后者在机械上非常软。

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.

随着自动门电机还必须选择噪音更少，稳定性高，省力，延长使用寿命的产品。不要选择使用质量差的电机，以节省成本，回到长期使用带来维修麻烦。

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.

两翼旋转门需要两个0.25kw的电机，以保证旋转门的平稳运行。其他门型选择一个0.37kw就可以了，转门时开门传感器的动作慢慢转动，门动作时，动作提升2秒钟恢复正常操作。当传感器移动时，转动门并立即停止转动，当动作释放时，在2秒钟内恢复正常操作。

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.

需要说明的是，旋转门电机一般在旋转门的天花板上方，门下很少。根据旋转门的配置，可能有许多传感器，空气开关，急停按钮，障碍按钮等等。

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.
