How does the brushed DC gear motor use its high torque characteristics to achieve smooth opening and closing?

In the automatic door system, the brushed DC gear motor uses its high torque characteristics to achieve smooth opening and closing mainly in the following aspects:

1. Dealing with the weight of the door
Automatic doors are usually heavy, especially large commercial doors or industrial doors. The brushed DC gear motor can provide high torque output at a lower speed through gear reduction, easily overcoming the weight of the door, so that the door can be opened and closed smoothly.

2. Smooth start and stop
In order to avoid violent shaking or impact when the door starts or stops, the brushed DC gear motor can use its high torque to quickly accelerate the movement of the door when starting, and slow down through appropriate control when stopping, ensuring that the door stops slowly, thereby avoiding damage to the mechanical structure and extending the life of the equipment.

3. Overcoming friction and wind resistance
During the movement of the door, in addition to overcoming the weight of the door itself, it is also necessary to deal with external forces such as track friction and wind resistance. The high torque output of the brushed DC gear motor ensures that the door remains stable despite these external forces, without jamming or jittering due to load changes.

4. Long-lasting and stable torque output
Automatic door systems often require frequent opening and closing, requiring the motor to provide continuous and stable torque output. The design of the brushed DC gear motor allows it to provide constant torque throughout the opening and closing process, avoiding the motor from being underpowered or overloaded during operation, ensuring the smooth operation of the door.

5. Dealing with sudden obstacles
If the door encounters an obstacle during the closing process, the motor will immediately feel additional resistance. The high torque characteristics of the brushed DC gear motor enable it to react quickly to avoid damage to the motor or door body, while ensuring that the door can continue to operate smoothly after the obstacle is removed.

6. Cooperation with the control system
The brushed DC gear motor is easy to cooperate with the automatic door control system, which can accurately control the motor speed and torque output through voltage regulation or pulse width modulation (PWM) signals. Through these control methods, the torque can be adjusted at different stages of the door opening and closing to achieve smooth starting, acceleration, deceleration and stopping.

The high torque characteristics of the Brushed DC gear motor ensure that the automatic door can operate smoothly and reliably under various working conditions, while extending the service life of the system.
