Ritscher
A tubular motor (or tube motor) is a compact, cylindrical electric motor designed specifically for automating roller blinds, Venetian blinds, shades, and awnings. Housed inside the blind's roller tube, it provides silent, wireless control of window coverings via remote, smartphone, or smart home systems.
✔ Space-Saving Design
Cylindrical shape (typical diameters: 28mm, 35mm, 42mm) fits inside hollow blind tubes.
Eliminates external mechanisms for a clean aesthetic.
✔ Quiet & Smooth Operation
Planetary gear systems reduce noise (<30 dB).
Soft start/stop prevents jerky movements.
✔ Smart Connectivity
Compatible with RF remotes, WiFi, Zigbee, Z-Wave, or voice control (Amazon Alexa/Google Home).
Programmable timers/schedules (e.g., sunrise/sunset automation).
✔ Safety & Durability
Auto-stop function detects obstructions (protects motor and blinds).
Overheat protection and durable brushless DC (BLDC) motors for long lifespan.
✔ Power Options
AC (110V/230V) for direct wiring.
DC (12V/24V) with battery backup (solar-compatible models available).
| Parameter | Typical Range |
|---|---|
| Diameter | 28mm / 35mm / 42mm |
| Torque | 5–50 Nm (varies by model) |
| Load Capacity | Up to 40 kg (for heavy blinds/awnings) |
| Travel Speed | 10–30 RPM |

Our company FAQ for you
(1) Q: What kind motors you can provide?
A:For now,we mainly provide Kitchen Hood Motor,DC Motor,Gear Motor,Fan Motor Refrigerator Motor,Hair Dryer Motor Blender Motor Mixer Motor,
Shade Pole Motor,Capacitor Motor,BLDC Motor PMDC Motor,Synchronous Motor,Stepping Motor etc.
(2) Q: Is it possible to visit your factory
A: Sure. But please kindly keep us posted a few days in advance. We need to check our
schedule to see if we are available then.
(3) Q: Can I get some samples
A: It depends. If only a few samples for personal use or replacement, I am afraid it will
be difficult for us to provide, because all of our motors are custom made and no stock
available if there is no further needs. If just sample testing before the official order and
our MOQ, price and other terms are acceptable, we'd love to provide samples.
(4) Q: Is there a MOQ for your motors?
A: Yes. The MOQ is between 1000~10,000pcs for different models after sample approval.
But it's also okay for us to accept smaller lots like a few dozens, hundreds or thousands
For the initial 3 orders after sample approval.For samples, there is no MOQ requirement. But the less the better (like no more than 5pcs) on condition that the quantity is enough in case any changes needed after initial testing.
