Quick Summary
A technical, quiet, and durable drive designed for modern blinds. Built for OEM integration and cordless safety.
32 mm tubular motor • cordless spring logic Stable torque, <40 dB acoustic profile, and Type-C charging. This electric tubular motor pairs with a cordless spring mechanism to keep roller shades precise, quiet, and safe—without pull cords.
What makes it practical
- Consistent output: torque consistency controlled within ±3% across batches.
- Quiet motion: balanced assembly keeps operation below 40 dB under rated load.
- Battery endurance: 2600/5200 mAh options, typical use 6–9 months per charge.
- Smart control: RF remote, push-to-start, and optional Tuya/Zigbee/BLE/Wi-Fi gateways.
- Install-friendly: LED feedback for pairing, limits, and low-battery prompts.
Engineering that stays quiet under load
Precision gearbox
Low-friction polymer-alloy gears with tuned meshing reduce vibration and keep torque delivery stable over frequent cycles.
Silent brake logic
Electromagnetic braking smooths start/stop transitions and protects delicate fabrics from snap or bounce.
Copper windings
High-purity copper coils manage temperature rise during continuous use and improve electrical efficiency.
Aluminum housing
Reinforced shell helps damp resonance and shields internals; compact profile suits small to medium shades.
Durability & protection
- Cycle testing: validated over 15,000 full open/close cycles.
- Thermal protection: auto pause on coil over-temperature; resumes when safe.
- Ingress design: IP20 as standard; sealing designs available up to light humidity use cases.
- Stall protection: automatic torque cut-off under overload conditions.
Control & integration
RF & cordless operation
Up to 15 channels (1–15; “A” for all). Push-to-start: a light double push on the bottom rail triggers motion—no cords involved.
LED logic: blue flash = power/operation; red flash ×2 = low battery; red/blue ×3 = setting success.
Smart-home ready
Optional gateways link with Tuya, Zigbee, BLE, or Wi-Fi to integrate with Alexa, Google Home, and Apple HomeKit (via Homebridge).

OEM/ODM
Private label, housing color, firmware/protocol options, and mechanical interface adjustments are available. Engineering support and remote training can be arranged for integrators and assembly teams.
Field feedback
In recent rollouts with a North American shades brand, end-user satisfaction rose while service calls dropped—mainly due to quieter motion and quicker setup using visual LED feedback and precise limit learning.
FAQ
1. What is a 32 mm Electric Motorized Cordless Spring Mechanism?
The 32 mm electric motorized cordless spring mechanism combines a DC tubular motor and a mechanical spring assist to provide smooth, balanced lifting for roller shades. The spring reduces motor load, improves torque stability, and eliminates safety risks associated with pull cords.
2. What are the typical technical parameters of the 32 mm tubular motor?
- Rated Torque: 0.7 Nm
- Rated Speed: 28 RPM
- Power: 5 W
- Battery Capacity: 2600 / 5200 mAh
- Protection Class: IP20
- Operating Temperature: 0–40 °C
3. How does the spring assist mechanism improve performance?
The spring mechanism balances gravitational force, reducing motor energy consumption during operation. This ensures longer battery life, quieter movement, and stable torque output even with heavier fabrics.
4. How long does the built-in battery last on a full charge?
When fully charged for 10 hours before first use, the motor can operate for 6–9 months under normal conditions. Red LED double-flash indicates low battery and prompts immediate charging.
5. Can I use solar charging or power banks?
Yes. The system supports Type-C USB charging via AC adapter, solar charger, or power bank. In “light-off charging mode,” the indicator LED stays off during charging for a discreet look.
6. How are the upper and lower limit positions set?
Use the R1 and P2 buttons to set top and bottom limits. The red and blue LEDs flashing alternately three times indicate successful learning or pairing. Repeat steps to reconfigure limits anytime.
7. What safety and protection features are included?
The 32 mm tubular motor offers low-battery protection, stall detection, and child-safe cordless operation. It complies with CPSC 16 CFR 1260 and EN 13120 standards to prevent cord loops and entanglement hazards.
8. Is this motor compatible with different shade types?
Yes. It is suitable for roller shades, zebra blinds, and honeycomb shades. Optional adapters are available for custom tube diameters such as 25 mm, 32 mm, and 38 mm systems.
9. How do I pair or remove a remote control?
Press the R1 button once to pair (LED flashes red + blue × 3). To delete all remotes, press R1 six times. The motor supports up to 15 control channels plus an “A” group mode for multi-motor control.
10. What maintenance is required for long-term use?
Recharge every 6 months, keep away from humidity, and avoid long button presses. Store after full charge and power-off (press R1 × 4) if unused for long periods to preserve battery health.
