Tubular Motor for Venetian Blinds
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.
Key Features & Benefits
✔ 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).
