Principle of Rolling Door Motor

• Motor and Gearbox Mechanism: The rolling door motor consists of an electric motor and a gearbox. The motor provides the rotational power, and the gearbox is used to adjust the speed and torque according to the requirements of the door. The gearbox reduces the high - speed, low - torque output of the motor to a lower - speed, high - torque output suitable for moving the heavy door. The output shaft of the gearbox is usually connected to a drum or a chain - drive system that is attached to the rolling door.
• Limit Switches and Control System: The motor is controlled by a control system that includes limit switches. These limit switches are used to determine the fully open and fully closed positions of the door. When the door reaches the desired position, the limit switch sends a signal to the control system to stop the motor. The control system can also be programmed to control the speed and direction of the motor, as well as to respond to external commands such as remote - control signals or signals from an automated building - management system.
• Power Transmission to the Door: The rotational force from the motor is transmitted to the rolling door through a mechanical connection. This can be via a chain, a belt, or a direct - drive system. In a chain - drive system, the motor turns a sprocket that moves a chain attached to the door's drum. The drum rotates, causing the door to roll up or down. In a direct - drive system, the motor's output shaft is directly connected to the door's drum, providing a more efficient and compact design.

Features of Rolling Door Motor

• Variable Speed Control: Many rolling door motors offer variable speed control.
