What are the safety protection measures of motorized roller shutter tubular motor?

Motorized roller shutter tubular motor is widely used in commercial places, garages and some residential rolling door systems. Its safety protection measures play a vital role in ensuring the safety of people and property.
First of all, overload protection is an important safety measure. When the rolling door encounters too much resistance during operation, such as being stuck by foreign objects or blocked by the track, the motor may be overloaded. At this time, the overload protection device inside the tubular motor will automatically start and stop the motor to prevent the motor from burning due to overload. At the same time, it also avoids damage to the rolling door structure due to forced operation, reducing safety hazards.
Secondly, limit protection is indispensable. The electric rolling door has a specific travel range during the opening and closing process, and the limit protection device can accurately sense the position of the rolling door. When the rolling door reaches the set upper opening limit or lower closing limit, the motor stops running immediately to ensure that the rolling door will not run excessively and deviate from the track or collide with surrounding objects. This function not only protects the rolling door itself, but also prevents accidental injuries to personnel and vehicles due to abnormal operation of the rolling door.
Thermal protection is also a key link. When the motor runs for a long time or works in a high temperature environment, the motor temperature will rise. The thermal protection device will monitor the motor temperature in real time. Once the temperature exceeds the safety threshold, it will automatically cut off the power supply and stop the motor from working. It will not be allowed to restart until the motor cools down to a safe temperature. This can effectively prevent the motor from causing safety accidents such as fire due to overheating and extend the service life of the motor.
In addition, some advanced Motorized roller shutter tubular motors are also equipped with obstacle rebound function. When the roller shutter door encounters obstacles such as pedestrians, vehicles or other objects during the descent process, the motor can quickly sense and reverse, so that the roller shutter door rises to avoid squeezing or colliding with the obstacles, providing active safety protection for people and property.
There are also leakage protection measures. Since the electric roller shutter door system involves electric drive, the leakage protection device can quickly cut off the power supply when the motor leaks, prevent the occurrence of electric shock accidents, and ensure the personal safety of users.
The electric roller shutter door tubular motor provides comprehensive protection for the safe operation of the roller shutter door through these multi-faceted safety protection measures. Whether in daily use or in special circumstances, it can effectively reduce safety risks, allowing users to use the electric roller shutter door system with confidence.
