Dooya DM25CE-S Automatic Blind Opener (DC Tubular Motor)
The Dooya DM25CE-S is a DC tubular motor designed for roller, venetian, and roman blinds, delivering 3-6 Nm of torque within a compact 25 mm diameter frame. Operating at a silent <35 dB noise level, this motor supports RF433 remote integration and manual bypass for reliable residential automation.
Quick Answer
The Dooya DM25CE-S is a silent (<35 dB), 25mm DC tubular motor providing 3-6 Nm of torque at 28 RPM. It operates on 12-24V DC and uses RF433 MHz for remote control. It is ideal for residential blinds where App or Voice control is not required, as it lacks native WiFi or Zigbee connectivity.
✓Silent <35 dB operation for bedroom environments
✓High-speed 28 RPM performance for efficient blind adjustment
✓Compact 25mm diameter fits inside standard blind rollers
✓Reliable 15,000-cycle lifespan (approx. 8 years of use)
✓Low-voltage 12-24V DC input compatible with solar charging
✓IP44 protection rating for dust and splash resistance
Choose the Dooya DM25CE-S if your priority is a silent, concealed motor for 25mm blind tubes and you prefer the simplicity of RF remote control. It is an excellent choice for low-voltage or solar-powered setups, though it lacks modern IoT connectivity.
✓ Who Should Buy
- • performance suitable for residential spaces.
- •Verified efficiency of standard rating for reduced long-term operational costs.
- •Structural stability for consistent cleaning under rigorous use cases.
- •Hardware durability via premium components and advanced technology.
- •Built-in grid protection with Standard power cycle voltage management.
✕ Who Should Avoid
- •Spaces or usage requirements exceeding residential rated capacity.
- •Installations prioritizing minimum capital expenditure over high-efficiency performance.
- •Unstable grid conditions exceeding the functional threshold of Standard power cycle.
- •Environments incompatible with automatic curtain physical and thermal dissipation specs.
Product Overview
The Dooya DM25CE-S is an automatic blind opener powered by a DC tubular motor delivering 3-6 Nm of torque for roller, Venetian, and Roman blinds. Operating at a quiet <35 dB noise level, this 25 mm diameter motor fits directly inside blind tubes for a concealed installation. The system runs on a DC 12-24V input, making it compatible with external battery packs or optional solar charging solutions for energy efficiency. With a rotational speed of 28 RPM, the DM25CE-S provides instant response times under 1 second using RF433 remote or switch integration. It lacks native WiFi or App control, focusing instead on reliable RF signaling and manual bypass functionality for power-independent operation. Built for residential durability, it is rated for 15,000 life cycles or approximately 8 years of use. Safety is managed through integrated overload, thermal, and under-voltage protection, while the IP44 rating ensures resistance against solid objects and splashing water.

Engineering Analysis
The engineering of the Dooya DM25CE-S centers on its 25mm tubular form factor, optimized for internal mounting within blind rollers. The DC motor architecture utilizes an energy-efficient design that supports a 3-6 Nm torque range, sufficient for standard residential blind weights. The 28 RPM output ensures a consistent opening speed while maintaining a silent operation profile below 35 dB. Reliability is reinforced by a duty cycle rated for 15,000 cycles and an MTBF of 20,000 hours. The inclusion of RF433 MHz protocol allows for local remote control without the latency of cloud-dependent systems. Protection circuitry includes a thermal fuse and auto-stop sensors that prevent motor burnout during mechanical jams. The 12-24V DC power requirement enables low-voltage wiring or off-grid solar integration, adhering to CE and RoHS safety standards for residential electronic components.
