How Electric Curtains Work: The Motor, the Movement, and Why It's Worth It

Electric curtains look like ordinary curtains when they're hanging, and that's deliberate, because the clever part is all hidden in the track above them. This guide pulls the track apart in plain English, so you can see how electric curtains actually work, what the motor does, how fast the curtains move, how much electricity they use, and why a bay window is the one place they outperform every manual track on the market. If you're trying to decide whether electric curtains are worth it for your house, start here, then jump to the electric curtains category page when you want to price one up.

The system we'll describe is the Silent Gliss Autoglide 5100, which is what we sell to the vast majority of domestic customers. The Silent Gliss 5600 works on the same principles but in a heavier-duty package. The mechanics below apply to both.

How electric curtains actually work inside the track

An electric curtain is a motor, a belt, a few precision gliders and a length of track, all hidden inside an extrusion that looks similar to a manual track from the outside but behaves entirely differently inside. Inside the track housing sits a small motor that drives a continuous belt or cord running the full length of the track. Your curtain hooks clip onto gliders, and those gliders are attached to the belt. When the motor runs, the belt moves, the gliders move, and your curtains open or close in a smooth, even pull from a single point of drive.

The hooks and gliders themselves work the same way as a manual track. There's nothing exotic about the hanging system. The intelligence is entirely in the motor and control unit.

The motor: small, quiet, and cheap to run

The Silent Gliss Autoglide 5100 uses a DC motor powered by a standard 13A plug socket. DC motors run more quietly and with finer speed control than AC alternatives, which is why Silent Gliss uses them across their domestic range.

Power consumption is minimal. When idle, the track draws roughly the same as a phone charger. Even during operation it uses very little electricity. Running your curtains twice a day for a year costs pennies in electricity.

The motor is housed entirely within the track extrusion. There's no separate motor box hanging off the end, no visible cables along the track face. From the front, it looks like any other quality curtain track.

Speed and movement: deliberate, not fast

The 5100 moves curtains at a steady, measured pace. A 3-metre span takes around 15 to 20 seconds to fully open. If you're expecting instant movement, it won't deliver that. But that's by design.

Slow, even movement looks elegant. It also means there's no momentum jerk at the end of travel, which reduces wear on both the fabric and the track. Heavy lined curtains travel just as smoothly as lightweight voiles because the motor provides consistent torque throughout the run.

Why "Silent Gliss" isn't just a name

The gliders in a Silent Gliss track are precision-engineered nylon components designed to run with almost no friction. In a manual track, each glider only matters when you're actively pulling the curtain. In an electric track, every glider is constantly in motion whenever the belt runs, so their quality matters far more.

In practice, the 5100 is genuinely quiet. You can hold a conversation in the room while the curtains are moving. There's a faint mechanical hum you'd notice in complete silence, but it won't register over normal background noise.

Bay windows: where electric curtains outperform manual ones

Manual tracks struggle with bay windows. The angled joints create friction points, the cord runs at awkward angles, and getting an even pull across a curved or angled bay requires some effort.

Electric tracks handle this naturally. The 5100 track extrusion can be bent to follow the curve or angle of your bay window. The motor drives the belt regardless of the track shape, so the curtains open and close smoothly without you needing to reach into the corners.

This is one of the most common reasons customers choose electric over manual. For more on this, see our guide to choosing the right electric curtain track for your bay window.

Electric vs manual: an honest comparison

• Cost: Electric tracks cost more upfront. For a 3-metre track with motor, budget considerably more than a quality manual equivalent. If budget is the only factor, manual wins.
• Fabric wear: Manual tracks concentrate wear wherever you grab the curtain. Electric tracks pull evenly from a fixed point on the leading edge, which distributes stress far more evenly. Over years, this makes a real difference to expensive fabric.
• Convenience: Remote control, app control, and timer functions mean your curtains can open at sunrise without you touching them. For high windows, awkward reaches, or anyone with limited mobility, this isn't a luxury. It's genuinely useful.
• Cord tangles: A common frustration with corded manual tracks, especially in households with children. Electric tracks have no accessible cords.
• Installation: Both need to be correctly fitted to the wall or ceiling. Electric tracks additionally need a nearby socket. This is worth planning at the fitting stage.

For most rooms where you're investing in quality curtains, the electric track is worth serious consideration. Not because it's high-tech, but because it's more practical over the long term.
