Somfy Swf Lift Motor Sl-01 [hot] Jun 2026
Many versions of this motor are battery-powered, meaning you don't need to hire an electrician to run new wires through your walls.
The Somfy SWF Lift Motor SL-01 is a compact, tubular DC motor designed specifically for lifting and lowering projection screens, flip-up TV lifts, and light-duty scissor lifts. Unlike standard roller shade motors (which rely on torque to rotate a tube), the "Lift" designation indicates that this motor is optimized for linear vertical movement —usually via a spool, cable, or belt drive system. somfy swf lift motor sl-01
Before purchasing, verify the amperage draw of your existing power supply. The SL-01 draws approximately 0.8A at 24V under full load. Undersized power supplies are the number one cause of "ghost stopping." Many versions of this motor are battery-powered, meaning
| Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | | No 24V power | Check power supply input (110V/240V side). Test DC output with multimeter (must read 24V). | | Motor clicks but does not turn | Overload or brake stuck | Reduce friction on lift spool. Check for twisted cable. The SL-01 cannot lift >10kg. | | Motor moves, stops mid-travel, then reverses | Thermal overload tripped | Wait 20 minutes. Reduce duty cycle. The motor is too small for the application. | | Motor runs opposite of button pressed | Direction not set | Press "UP" then press "MY" (2 sec) on the remote. The direction flips globally. | | Remote works 1/10 times | RF interference or low battery | Change remote battery (CR2430). Move WiFi routers/ballasts away from motor head. | | Hums but doesn't lift | Mechanical jam or stripped spool | Disengage motor shaft. Spin spool by hand. If stuck, open casing. | Before purchasing, verify the amperage draw of your
Electric tab-tensioned screens have heavy rollers and tension cables. The SL-01 provides the smooth, low-vibration start required to prevent fabric wrinkles during deployment.
Easily set "upper" and "lower" stop positions so your blinds always line up perfectly. Quick Setup Tips
If your "Up" button makes the blind go down, hold the "my" button until it jogs to reverse the motor's direction.
