Otis Elevator door Controller At120 Faa24350bk1 Elevator door machine inverter box

‌The Otis AT120 door controller is a device used to control elevator doors. It consists of a motor, a reducer, a drive device, and a control system. The AT120 door controller drives the reducer through the motor, and then the drive device controls the opening and closing of the door. The control system accurately controls the movement of the door according to the preset program and the information fed back by the sensor to ensure its safety and reliability.

The basic structure of the AT120 door controller includes a DC motor and a DC drive gearbox. The motor drives the door leaf to move linearly through a reduction gear. The position of the door panel is determined by a speed encoder installed on the motor shaft. Whether it is a center-opening or side-opening door leaf, one leaf is driven by the lower end of the toothed belt, and the other leaf is driven by an aviation wire rope.
