1. What Exactly Is a Tubular Motor?
Let's start simple.
A tubular motor is basically a strong, quiet motor that sits inside a metal tube. That tube fits right into the roller of a blind, a shade, or an awning. Once it's installed, you don't see the motor at all. You just see the fabric moving up and down.
This is why people call it the hidden heart of motorized shading.
Instead of pulling a chain or cranking a handle, you push a button – or use your phone. That's the big shift. Tubular motors turned manual shades into smart ones.
2. Why the Sun Shading Market Loves Tubular Motors
If you've ever sold, installed, or used motorized blinds, you know the struggle. Old motors were bulky, noisy, and hard to hide. Tubular motors solved that.
Here's why they took over the sun shading industry:
They hide completely – No ugly boxes on the wall. The motor lives inside the roller tube.
They run quietly – A good tubular motor stays under 45 dB. That's library-level quiet.
They last – Because the motor is sealed inside the tube, dust and moisture don't get in.
They're smart – Most modern ones work with apps, remotes, and voice control.
In short: tubular motors made sun shading products more reliable, quieter, and easier to sell.
3. Main Applications in the Sun Shading Market
Tubular motors are everywhere once you start looking. Here are the most common places you'll find them.
3.1 Electric Roller Blinds
This is the most popular use. The motor sits inside the roller tube. When it turns, the fabric rolls up or down.
Where you see them: Offices, homes, hotels, meeting rooms.
Typical specs: 35mm or 45mm tube diameter. Torque from 10 Nm up to 50 Nm for most homes.
Real-life example: A 45mm tubular motor with 20 Nm torque can easily handle a 3m wide blackout blind.
3.2 Motorized Venetian Blinds
Venetian blinds need two movements: lifting the slats up and down, and tilting them to control light. A regular motor can't do that alone.
How tubular motors handle it: The motor works with a special cord winder. One motor handles both lifting and tilting.
Where you see them: Offices, home offices, bathrooms, conference rooms.
Pro tip: Look for motors labeled "venetian ready" – they come with the right cord winder system.
3.3 Outdoor Awnings
Outdoor shading is tougher. The motor has to handle heat, rain, dust, and wind.
What changes for outdoor use: The motor needs better sealing. The awning fabric is usually acrylic (sun-resistant). The frame is aluminum (rust-proof).
Torque needs: Outdoor awnings usually need 50 Nm to 100 Nm, sometimes more for large units.
Real product example: The DM45R series from a major brand like Dooya runs on 110–230V and is made specifically for awnings.
3.4 Smart Ready-Made Shades
This is a newer trend. The tubular motor comes pre-installed inside the shade from the factory. You buy the whole thing as one product – no assembly, no guesswork.
Why people like them: You don't have to pick a motor, a tube, and a fabric separately. It's plug-and-play.
Where you see them: New apartments, smart home upgrades, rental properties.
Tech inside: These usually use 35mm super-slim motors and support Zigbee, Wi-Fi, or Matter.
3.5 Large Commercial Shading Systems
For big projects – like stadiums, airports, or shopping malls – you need serious power.
What they use: 92mm tubular motors with 200–450 Nm torque. Some come in hand-crank backup versions or variable speed versions.
Where you see them: Atriums, skylights, factory windows, sports arenas.
4. How to Pick the Right Tubular Motor for a Shading Project
If you're a contractor or builder, this is where you need to get it right. Picking the wrong motor means callbacks and frustrated customers.
Here's a simple guide.
Step 1 – Figure Out the Torque You Need
Torque is how strong the motor is. More fabric weight = more torque.
A rough rule of thumb:
Small window (2m wide, light fabric): 10 Nm
Normal room blind (3m wide, blackout fabric): 20–30 Nm
Large living room blind (4m+ wide): 40–50 Nm
Outdoor awning: 50–100 Nm
Commercial heavy fabric: 200 Nm+
Golden rule: Go one size up from what you think you need. A slightly oversized motor runs cooler and lasts longer.
Step 2 – Choose the Tube Diameter
Tube diameter is directly linked to torque.
35mm → small blinds, smart ready-mades (up to ~10 Nm)
45mm → standard home and office blinds (10–50 Nm)
59mm → larger residential blinds (50–100 Nm)
92mm → commercial and industrial (200–450 Nm)
For most homes, 45mm is the sweet spot.
Step 3 – Decide on Smart Features
Do you need smart home integration? Ask these questions:
Will the customer use a phone app?
Do they have Alexa or Google Home?
Will the blinds work with other smart devices (lights, sensors, thermostats)?
If yes, look for motors that support Zigbee, Wi-Fi, Bluetooth Mesh, or Matter.
If not, a simple RF remote is fine. It's cheaper and still very convenient.
Step 4 – Check Safety and Certifications
This is non-negotiable.
At a minimum, look for:
CE (Europe)
UL (North America)
CCC (China)
Also check for obstacle detection – the motor should stop and reverse if the blind hits something.
Step 5 – Pick a Reliable Brand
Stick with names that have been around. In the tubular motor space, these are solid:
Dooya (China – large volume, good quality)
A-OK (China – strong on patents, no price war)
Somfy (France – premium, very reliable)
Wintop (global – wide range)
Cheap no-name motors often fail within a year. You don't want that call on a Sunday morning.
5. Smart Trends: Where Tubular Motors Are Going
The sun shading market isn't standing still. Tubular motors are getting smarter.
Here's what's happening right now.
Multi-Protocol Support
Older motors only worked with one remote. New ones support RF433, Zigbee, Wi-Fi, Bluetooth Mesh, and Matter – sometimes all in one.
That means the same motor can work with a basic remote today and a full smart home system next year.
All-in-One Design
The motor, the power supply, and the smart module are now packed into one tube. No external control box. No messy wiring.
This is huge for installers. Faster install, fewer things to break.
Scene Automation
A smart tubular motor can talk to other devices.
Too much sun? The awning comes down automatically.
Sun goes down? The blinds close.
Door opens? The shade goes up.
This used to be high-end only. Now it's becoming standard.
What's Coming Next
Smaller tubes – 35mm is common now. 25mm is in development.
Quieter motors – Sub-30 dB is the goal (almost silent).
Better energy efficiency – New magnetic materials help.
Matter standard – One protocol to rule them all. Big brands are already moving.
6. Market Snapshot (For Those Who Like Numbers)
The tubular motor market is growing steadily.
China market (2024): ~8.1 billion RMB. Expected to reach ~10.5 billion RMB by 2027. That's about 10.8% growth per year.
Global AC tubular motor market (2031 forecast): ~52 billion RMB, growing at 4.5% annually.
Why the growth?
Smart homes are mainstream now, not a luxury.
Energy codes push builders to use automated shading for efficiency.
Better products mean fewer failures and happier customers.
7. Quick FAQ – What People Actually Ask
Q: Can I install a tubular motor myself?
A: If you're handy, yes – but you'll need basic wiring skills. For outdoor awnings or heavy blinds, hire a pro. One mistake can damage the fabric or tube.
Q: What happens if the power goes out?
A: Good tubular motors have a manual override. You pull a small cord or turn a key, then move the blind by hand.
Q: How long do they last?
A: Quality motors last 10+ years. Many brands offer 5-year warranties.
Q: Will the motor work with my existing blinds?
A: Sometimes. But it's usually easier to buy a motorized blind ready-made. Retrofitting is possible but takes more work.
Q: Do I need a different motor for outdoor use?
A: Yes. Outdoor motors have better sealing against moisture and dust. A regular indoor motor will fail quickly outside.
Final Takeaway
A tubular motor is a simple idea – a motor inside a tube – but it changed the sun shading market completely.
It made blinds and awnings quieter, stronger, and smarter. And because the motor hides inside the roller, the product looks clean and professional.
Whether you're a homeowner upgrading one window, or a contractor bidding on a 200-blind office project, getting the tubular motor right matters. Match the torque to the load, pick the right diameter, and don't skip the smart features if your customer wants them.
That's how you build shading solutions that work – and that people actually enjoy using.
