When it comes to automating metal shutters or roll-up doors, tubular motors They are one of the most reliable and widespread solutions. They are hidden inside the shaft, do not alter aesthetics and offer smooth, quiet and very durable operation.
If you’re looking for everyday convenience and a well-resolved system, here’s everything you need to know.
What is a tubular door motor?
A tubular motor is a cylindrical device that is installed inside the shaft tube of the roller shutter or roller shutter. From there, it directly activates the raising and lowering of the closure, being completely integrated into the system.
This type of motor is very common in commercial blinds and rolling/residential garage doors, as it simplifies installation and reduces external elements. There are versions designed for different tube diameters and stems.
Features of tubular motors
Tubular motors They stand out for their technical versatility. Some of its most relevant features are:
- Wide power range: There are models that range from low torques for light blinds to motors capable of moving heavy closures. In the catalogue we find options from a few Nm to 120 Nm motors.
- Compatibility with different axes: They adapt to tubes of different diameters, which allows the motor to be adjusted exactly to the type of door installed. This is where solutions like the SQ90RSE tubular motor, ideal for large tubes and more demanding closures.
- Precise limit switches: They incorporate mechanical or electronic limit switches that allow the upper and lower stop point to be precisely adjusted, avoiding unnecessary efforts and extending the useful life of the mechanical or electronic assembly.
- Integrated safety: Many models include obstacle detection, automatic reverse and overload protection, especially in the downward movement. This provides peace of mind both in shops and garages.
- Quiet and stable operation: Working from inside the shaft, the movement is more uniform. Less vibrations, less noise and less wear on guides and slats.
- Manual manoeuvring options: In the event of a power cut, there are versions with an auxiliary manoeuvre that allow the door to be operated manually without complications. A key detail in commercial/residential shutters.

Why install tubular motors on your automatic doors?
Choosing tubular motors is not only a technical matter, it is also a practical decision for everyday use.
- Full integration: The motor is hidden inside the shaft, which maintains a clean and professional installation. Nothing stands out or breaks the aesthetics of the closure.
- Space saving: As you do not need external motors or side systems, the set takes up less space. This is especially useful in tight drawers or small gaps.
- Increased system durability: A well-sized motor works without straining. If it is also correctly selected according to weight, height and shaft diameter (e.g. using selection tables), the result is a system that lasts for years without problems.
- Comfort and safety: Opening and closing with a button, remote or automatic system completely changes the user experience.
Portalum: Automatic doors with the best motors!
At Portalum we don’t install random motors. We analyse the actual weight of the door, the diameter of the shaft, the height of the closure and the frequency of use to choose the most suitable tubular motor in each case.
We work with tubular motors of leading brands, selected with technical criteria and assembled with all the necessary accessories: mounts, adapters, fall arrest systems and fine adjustments of limit switches.
The result is an automatic door that is reliable, quiet and ready to last.
If you are thinking of automating your roller shutter / roller shutter or renewing the motor, we advise you so that you get it right from the first moment.
