Shutter motors
A shutter motor is the electric drive that raises and lowers a roller shutter, usually a tubular motor inside the barrel or an external unit at the side. It has limit settings for the open and closed positions, and often a manual override for power cuts.
Where does it work well?
Frontages where shutters are opened daily, wider or heavier curtains that are hard to lift by hand, and landlords or staff who want key switch, button or remote control instead of manual lifting.
Pros
- Easier daily operation
- Remote and key switch options
- Suits wider, heavier curtains
- Limit settings protect the curtain
Cons
- Needs a power supply and a safe override
- Water and heavy use shorten its life
- Older motors may be hard to match
How long does it last?
Typically several years on a daily-use shutter, with manufacturers' warranties covering the motor itself.
What should you check when buying?
Size the motor to the curtain weight and barrel, and check its duty rating against how often it runs. Ask how the shutter is opened in a power cut. BS EN 13241 covers the product, and BS EN 12453 covers safety in use.
Common questions
Can a manual shutter be converted to electric?
Often yes, if the barrel, curtain and box can take a motor and there is a power supply nearby. We check the curtain weight and existing springs first. A very old or damaged shutter may be better replaced than converted.
Why does my shutter motor hum but not move?
Often the curtain has jammed, a brake has stuck or the motor has an internal fault. A thermal cut-out can also stop it after repeated use, so let it cool. If it stays stuck, stop using it and book a repair.
