Shade Torque Calculator
Understanding the torque requirements for a shade is important to select the appropriate controller to be used for it. Rollease Acmeda Torque Calculator is a tool that uses specific shade data points to calculate the torque on up to three linked shades and lists compatible manual clutches, motors and link systems for specific applications based on those results.
Use this calculator to validate the strength of the clutch or motor to be used on specific shades.
This calculator considers torque requirements only, not any other system limitations. A separate Shade Fabricator Calculator is available for additional system limitations.
This calculator can work with up to three shades. Enter "0" for the width and drop of shades 2 and/or 3 if not needed.
How to use the Torque Calculator
Before you begin, select the language (English or Spanish); and the Measuring System (Metric or Imperial) at the top, right-hand side of the file.
Note: the Roll Size, Shade Torque and Link Torque under each shade will update as shade details are populated in the calculator.
1. Enter the width of shade 1 (in inches) in the highlighted cell under "Shade 1"
2. Enter the width of shades 2 and 3 if needed in the corresponding highlighted cells.
Under "Select Configurations":
3. Enter the Shade Drop in inches
4. Select the fabric from the Fabric drop-down menu.
* Note: you can select "custom" at the bottom of the options list, then enter the custom fabric details under the "Input Following Custom Parts" section.
5. Select the hem bar from the Hem Bar drop-down menu.
* Note: you can select "custom" at the bottom of the options list, then enter the custom hem bar details under "Input Following Custom Parts".
6. Select a ballast option.
* Note: you can select "custom" at the bottom of the options list, then enter the custom ballast details under "Input Following Custom Parts".
7. Select from the Pre-wrap drop-down menu.
8. Select from the Tube drop-down menu.
9. Review the System Summary to determine appropriate shade components:
- Control Torque Requirement.
- Total Shade Weight.
- Link Torque Requirement (if two or more linked shades).
- Compatible components.
