motorized window blinds

shades and blind motors with remote control Our high quality RollerTrolâ„¢ DC tubular motors with state-of-the-art remote control systems are precision engineered to exacting standards.

These motors are perfect for making custom remote control window blinds and shades, skylight shades, projector screens, awnings, banners, conveyers or any application where you need a rotating tube.

We hope the following information and specifications will help you make the right choice when selecting a motor size, but please feel free to contact us at any time if you have any questions.

The most important factors when choosing the right motor for blinds or other applications are power requirements, drive size, lift capacity, and control options:

Input Voltage: All our DC motors operate on safe 12v DC. You can operate them from a large RV 12v battery with a trickle charger (makes a great UPS), or use our 12v AC/DC adapters. We also have motors with built-in batteries that require no wiring at all.

Drive size: 18mm adapters fit 1" (25mm) OD tube, 35mm adapters fit 1.5" (38 mm) OD tube, 36mm adapters fit 1.75" (45 mm) OD tube (Please note: wall thickness on tubing varies; please check inside diameter to see if drive wheel fits inside)

Lift capacities: Mini Series: 4 lb (1.8 kg), Standard Series: 12 lb (5.5 kg), HD Series: 24 lb (11 kg), MAXI Series: 45 lb (20 kg)

Making the Right Choice:

The first step is to calculate the weight of your intended load. If your application is for shades, blinds, screens or any other project that uses fabric or some type of material on a roller tube, you may first want to read our article about how to calculate blind or shade material weight. Note that the length or weight of the roller tube has little effect on the motor requirements, but the diameter of your tube and the fabric or load weight does.

Once you have an idea of your load requirements and tube size, use the table above to select the right motor (mouse over the table cells for explanation of a particular parameter). You can also see more detailed information and further comparison information by clicking on the model number of the motor in the table. This will take you to the appropriate page in our tubular motor and automation product catalog.

We sincerely hope you enjoy using these advanced tubular motors; if you have any questions, please feel free to contact us at any time!
