伸缩门怎样设计的

How to design telescopic doors

电动机的工作原理电动机是把电能转换成机械能的设备。在机械、治金、石油、牒炭、化学、航空、交通、农业以及其他各种工业中，电动机被广泛地应用着。随着工业自动化程度不断提高，需要采用各种各样的控制电机作为自动化系统的元件，人造卫星的自动控制系統中，电机也是不可缺少的。此外在国防、文教、医疗及日常生活中（现代化的家电工业中）电动机也胞来愈广泛地应用起来。

The working principle of an electric motor is a device that converts electrical energy into mechanical energy. Electric motors are widely used in machinery, gold, petroleum, carbon, chemistry, aviation, transportation, agriculture and other industries. With the continuous improvement of industrial automation, it is necessary to use a variety of control motors as the components of the automation system. In the automatic control system of artificial satellites, motors are also indispensable. In addition, in the national defense, culture and education, medical and daily life (modern household appliances industry) motor is also increasingly widely used.

一般电动机主要由两部分组成：固定部分称为定子，旋转部分称为转子。另外还有端盖、风扇、罩壳、机座、接线盒等。电动机的工作原理是建立在电磁感应定律、全电路欧姆定律、和电磁力定律等基础上的。当磁极沿顺时针方向旋转，磁极的磁力线切割转子导条，导条中就感应出电动势。电动势的方向由右手定则来确定。因为运动是相对的，假如磁极不动，转子导条沿逆时针方向旋转，则导条中同样也能感应出电动势来。在电动势的作用下，闭合的导条中就产生电流。该电流与旋转磁极的磁场相互作用，而使转子导条受到电磁力（安培力），电磁力的方向可用左手定则确定。由电磁力进而产生电磁转矩，转子就转动起来。在该设计中电动机是用来带动电动伸缩门的开与关，完成对电动伸缩门的控制。

The general motor consists of two parts: the fixed part is called the stator and the rotating part is called the rotor. There are also end covers, fans, shrouds, chassis, junction boxes and so on. The working principle of the motor is based on the law of electromagnetic induction, Ohm law of the whole circuit, and the law of electromagnetic force. When the magnetic pole rotates clockwise, the magnetic force of the magnetic pole cuts the rotor guide bar, and the electromotive force is induced in the guide bar. The direction of the electromotive force is determined by the right hand rule. Because the motion is relative, if the magnetic pole does not move and the rotor guide bar rotates counterclockwise, the electromotive force can also be induced in the guide bar. Under the action of electromotive force, current is generated in the closed guide bar. The current interacts with the magnetic field of the rotating magnetic pole and causes the rotor guide bar to be subjected to electromagnetic force (ampere force). The direction of the electromagnetic force can be determined by the left-hand rule. The electromagnetic torque is generated by electromagnetic force, and the rotor rotates. In this design, the motor is used to drive the opening and closing of the electric expansion door to complete the control of the electric expansion door.

电动伸缩门的构成及工作原理电动伸缩门的组成：电动伸缩门主要由门体、驱动器、控制系统构成。门体采用优质不锈钢及铝合金专用型材制作，采用平行四边形原理较接，伸缩灵活行程大。驱动器采用特种电机駆动，杆蜗轮减速，并没有手动离合器，停电时可手动启闭，控制系统有控制板，按钮开关，另可根据用户需求配备无线控装置。可配备动显示屏，显示500字的显示内容。还可配备智能红外线双探头防碰撞装置，遇人或异物20－300M可自动返回运行，从而保车辆及行人的安全。

The composition and working principle of the electric telescopic door: The electric telescopic door is mainly composed of the door body, the driver and the control system. The door body is made of high quality stainless steel and aluminum alloy special profiles, and adopts the principle of parallelogram to connect with each other. It has a flexible stretching stroke. The driver adopts special motor to move on the heel, reduces the speed of worm wheel, and has no manual clutch. When power is cut off, it can be opened and closed manually. The control system has control board, button switch and wireless control device according to user's demand. It can be equipped with dynamic display screen to display 500 words of display content. It can also be equipped with intelligent infrared dual-probe anti-collision device, 20-300M people or foreign bodies can automatically return to run, thus ensuring the safety of vehicles and pedestrians.
