What is the lifting capacity of the Dooya DV40AF-S?

The DV40AF-S provides 40Nm of torque, specifically optimized for the heavy vertical lift requirements of wooden venetian blinds.

Does this motor support voice control via Alexa or Google Home?

No, the DV40AF-S does not feature native Wi-Fi or voice assistant integration; it operates via RF433 remote, wired switches, or RS232/485 external interfaces.

What size tube is required for the DV40AF-S?

The motor has a 40mm diameter and is designed to be mounted inside standard 40mm tubular blind rollers.

How long can the motor run continuously?

The DV40AF-S is rated for a 6-minute continuous duty cycle before the thermal protection requires a cooling period.

Dooya DV40AF-S 40Nm Automatic Blind Motor

The Dooya DV40AF-S is a high-torque 40Nm AC tubular motor designed specifically for the automation of wooden venetian blinds. Operating at a fixed speed of 28 RPM, this 220-240V AC unit fits standard 40mm diameter tubes and delivers silent operation measured at less than 40 dB. Built with a 6-minute continuous duty cycle and an IP44 protection rating, it provides a mechanical lift solution for heavy window treatments without requiring complex smart home hubs.

Product Overview

The Dooya DV40AF-S is a professional-grade AC tubular motor engineered for heavy wooden venetian blinds, delivering a robust 40Nm torque capacity. Operating on 220-240V AC at 50Hz, this single-phase motor achieves a rotation speed of 28 RPM, ensuring efficient tilt and lift functionality for substantial slat weights. Its 40mm diameter allows for internal mounting within standard blind tubes, while the steel and plastic powder-coated body ensures structural integrity across a 10-year lifespan. Unlike smart-only models, the DV40AF-S focuses on reliability through RF433 integration and physical switch controls, omitting Wi-Fi or Bluetooth to prioritize signal stability. The unit includes a manual override bypass and a thermal protection circuit to prevent overheating during its 6-minute duty cycle. Performance is validated by CE and RoHS certifications, maintaining an operating temperature range of -20°C to +60°C. With a noise rating of < 40 dB, this motor is suitable for environments where acoustic discretion is required alongside mechanical power.

Engineering Analysis

The engineering of the DV40AF-S centers on its 40Nm torque density within a compact 40mm tubular frame. The AC motor architecture is optimized for 220-240V inputs, utilizing a 6-minute duty cycle that far exceeds the typical 4-minute residential standard. Its silent operation (< 40 dB) is achieved through precision-balanced internal gearing, which manages the 28 RPM output without resonant vibration. Thermal protection and anti-jamming sensors are integrated into the circuit to protect the 40Nm gearbox from strain. The IP44 rating confirms the motor's resistance to solid objects over 1mm and water splashes, while the 20,000-cycle mechanical life rating ensures over a decade of operation at two cycles per day. Control is managed via an RF433 radio frequency or hardwired switch, providing a low-latency response time of less than one second without the dependency on external cloud servers or local network stability.
