自动门分为：旋转门、弧形门、平移门、感应电动门、紧急疏散平移门、重叠门、折叠门、90度推开门、快速门等多种类别
Automatic doors are divided into various categories such as revolving doors, curved doors, sliding doors, induction electric doors, emergency evacuation sliding doors, overlapping doors, folding doors, 90 degree sliding doors, and fast doors
自动门开始在建筑物上使用，是在二十世纪年以后。二十年代后期，美国的超级市场的开放，自动门开始被使用。1930年，美国史丹利率先推出世界上第一樘自动门（此史料记载于纽约时报）。其后，世界第一自动门品牌多玛在1945年将油压式、空气式自动门广泛推向市场，新建大楼的正门也开始使用了。到了1962年，电气式已开始出现，之后伴随着城市的建设，自动门技术的领域每年都在增加。当初，用供给建筑物用电源进行电动机的速度控制很难，只好进行油压、空压速度控制，转换但因能源利用效率很低，然而伴随着电气控制的技术发展，电气控制技术已经成熟，直接控制电动机的电气式自动门逐渐成为主流。例如：各种用可识别控制的自动专用门，如：感应自动门（红外感应，微波感应，触摸感应，脚踏感应）、刷卡自动门等。
Automatic doors began to be used in buildings after the 20th century. In the late 1920s, with the opening of supermarkets in the United States, automatic doors began to be used. In 1930, Stan&Co. of the United States first introduced the world's first automatic door (this historical record is recorded in The New York Times). Afterwards, the world's first automatic door brand, Doma, widely introduced hydraulic and air operated automatic doors to the market in 1945, and the main doors of newly built buildings also began to be used. By 1962, electrification had begun to emerge, and with the construction of cities, the field of automatic door technology had been increasing every year. At first, it was difficult to control the speed of electric motors using power supply for buildings, so oil pressure and air pressure speed control had to be carried out. However, due to low energy utilization efficiency, with the development of electrical control technology, electrical control technology has matured, and electrical automatic doors that directly control motors have gradually become mainstream. For example, various automatic dedicated doors that can be recognized and controlled, such as induction automatic doors (infrared sensing, microwave sensing, touch sensing, foot sensing), card swiping automatic doors, etc.
