Dooya DM35SL 6-28: 35mm AC Tubular Motor with Manual Override
The Dooya DM35SL 6-28 is a specialized 35mm AC tubular motor designed for roller and honeycomb blinds, providing 6Nm of torque at a consistent 28 RPM speed. It operates at an ultra-quiet noise level of less than 40 dB and features a built-in manual bypass for mechanical override. This 220-240V AC motor is rated for 20,000 cycles and carries an IP44 protection rating, ensuring longevity in both residential and commercial settings.
Quick Answer
The Dooya DM35SL 6-28 is ideal for motorized blinds requiring 6Nm of torque and 28 RPM operating speed. It features a <40dB noise level and a manual bypass for use without power. It does not support native App or Voice control, relying instead on RF433 remote or switch integration.
✓6Nm torque capacity for medium-to-heavy roller blinds
✓28 RPM high-speed operation for efficient blind deployment
✓Silent operation engineering maintaining noise levels below 40 dB
✓Mechanical manual bypass for operation during power failure
✓35mm diameter fits standard tubular blind rollers
✓IP44-rated housing for dust and splash resistance
✓20,000+ cycle mechanical lifespan for long-term reliability
Choose the Dooya DM35SL 6-28 if you prioritize mechanical reliability and manual fail-safes over smart home connectivity. Its 6Nm torque and silent 40dB operation make it a premier choice for standard AC-powered blind automation.

Product Overview
The Dooya DM35SL 6-28 is a high-performance 35mm AC tubular motor engineered for the precise automation of roller, Venetian, and honeycomb blinds. Delivering 6Nm of torque at a fixed speed of 28 RPM, this motor provides the mechanical force necessary for consistent vertical movement without the lag associated with lower-voltage battery units. Running on a standard 220-240V AC supply at 50Hz, the DM35SL 6-28 eliminates the need for external power bricks or frequent recharging. Its acoustic profile is strictly controlled to remain under 40 dB, ensuring that blind adjustments do not disrupt quiet environments. A standout feature of this specific model is the integrated manual bypass, which allows for physical manual override in the event of an electrical outage. While the unit lacks native Wi-Fi or Bluetooth, its RF433 compatibility and switch integration make it a reliable choice for hardwired installations. Safety is managed through a comprehensive suite of internal protections, including thermal cutoff after a 6-minute duty cycle and over-voltage shielding. The motor is encased in a corrosion-resistant steel and plastic housing, designed to fit inside the tube of the blind assembly for a concealed installation.

Engineering Analysis
Engineering analysis of the DM35SL 6-28 reveals a robust single-phase AC architecture designed for a 10-year lifespan under normal 30,000-hour MTBF conditions. The 6Nm torque output is paired with a 28 RPM gearbox, optimizing the balance between lifting capacity and travel time. Unlike standard electronic motors, the manual bypass mechanism uses a secondary mechanical linkage, ensuring that the blind remains functional regardless of the status of the AC power source. Thermal management is critical in this model, with a 6-minute continuous run-time limit before the automatic thermal protection engages to preserve the internal windings. The IP44 rating confirms that the internal electronics are protected against particles larger than 1mm and water splashes from any direction, making it suitable for high-humidity residential areas. Precision control is maintained through high-efficiency motor windings that respond in less than 1 second to RF433 signals or hardwired switch inputs. This motor does not utilize a digital logic board for smart scheduling, focusing instead on high-torque mechanical reliability.
