Motorised roller shutters bring sun control, security and comfort down to a single button. We explain how tubular motors work, how to choose torque, how they differ from manual systems and what maintenance they need.
During Muğla’s long, sunny summers, roller shutters are one of the most effective ways to keep a house cool. When sunlight is stopped outside before it reaches the glass, the interior heats up far less; curtains and internal blinds act only after the heat has reached the glass, so they do not have the same effect. The benefit of shutters is clear, but manual shutters operated by a strap or crank can be tiresome in daily use. Motorised roller shutters greatly increase comfort here. In this article we explain the advantages of motorised shutters, how to choose the right motor and maintenance tips.
How does a motorised roller shutter work?
In motorised shutters, a tubular electric motor is placed inside the winding tube (axle) in the shutter box. When the motor runs, the tube turns and the shutter slats are wound up or unrolled downwards. The motor contains limit settings that define the top and bottom positions of the shutter, so it stops at the correct point every time.
Control options are wide: wall switch, remote control, timer, sun and wind sensors or, in suitable systems, smart home apps. Group controls that operate several shutters at once with a single button are also possible.
Advantages of motorised roller shutters
- Comfort: Even wide, heavy shutters open and close with a single button. They are easy to use for the elderly and children.
- Energy savings: With a timer, shutters on sun-exposed facades can lower automatically in the midday heat. This reduces the air conditioning load during the hot summers of Dalaman and Ortaca.
- Security: A closed shutter makes direct access to the glass harder. With some motors, security can be increased with anti-lift locking accessories.
- Practicality for holiday homes: Shutters opening and closing at set times while the house is empty make it look occupied. Lowering all shutters with one button when closing up for the off-season saves time.
- Longer life: Common faults of manual systems, such as broken straps and strained crank mechanisms, are eliminated.
Choosing the right motor and torque
The most important value when choosing a motor is torque. Torque expresses the motor’s ability to lift the shutter’s weight and is measured in newton metres (Nm). The required torque is calculated from the shutter’s width, height, slat material (aluminium, PVC, steel) and the diameter of the winding tube. For example, a shutter of the same size with foam-filled aluminium slats is heavier than one with PVC slats and needs a stronger motor.
An underpowered motor is strained, overheats and repeatedly stops as its thermal protection trips; its life is shortened. An overpowered motor adds unnecessary cost and, without obstacle detection, can damage the slats. The torque calculation should therefore be made together with the shutter size and slat type.
| Feature | Strap / crank | Motorised |
|---|---|---|
| Ease of use | Moderate, hard in large sizes | Very easy |
| Automation | None | Timer, sensors, smart home |
| Common faults | Broken strap, worn pulley | Limit setting drift, electrical issue |
| Power requirement | None | Yes (wired) or wireless control |
| Initial cost | Low | Higher |
Power cuts and safety
The most common question about motorised shutters is what happens during a power cut. Some motors come with a manual emergency override; in these systems the shutter can be opened by hand using a crank. Especially where the only exit is a shuttered door, such as a garden exit or shop shutters, the emergency override is important. The cabling must also be of the right cross-section, protected by a fuse and shielded from moisture. Having a qualified electrician make the electrical connection is essential for safety.
Maintaining motorised roller shutters
- Cleaning the slats: Wipe the slats a few times a year with lukewarm water and mild detergent. In seaside homes, salt build-up can dull the slat surface.
- Cleaning the guide rails: Dust, sand and insect debris collecting in the side guides make movement harder. Clean them with a brush and damp cloth and apply silicone spray if needed. Oil-based products are not recommended, as they attract dust.
- Checking for obstacles: Make sure no plant pots, furniture or air conditioning pipes obstruct the shutter as it lowers.
- Icing and wind: In strong storms, half-open shutters can suffer slat damage. In windy weather it is safer to keep the shutter fully open or fully closed.
- Limit setting: If the shutter does not lower fully or stops with strain at the top, the limit setting may have drifted. Depending on the motor type, it is adjusted with a special setting cable or screw; it is best done by a technician.
Can an existing shutter be motorised?
In most cases, yes. If the shutter box and winding tube are of suitable size, a tubular motor can be fitted to an existing strap-operated shutter. There must be enough space in the box, the tube must have a diameter suitable for the motor, and a power supply must be available. If the slats and guides are in good condition, this conversion can be more economical than a completely new shutter. Where running cables is difficult, wireless systems powered by batteries or solar panels can also be considered.
Conclusion
A motorised roller shutter is a smart investment that provides sun control in a hot climate, security in holiday homes and comfort in daily use. For a long life, the right torque, a proper electrical installation and regular cleaning of the guides are all it takes.
