This guide helps you quickly identify the right motor for your application and usage scenario.
Tubular Motor Selection Chart & Torque Calculation Guide
Looking for the right tubular motor for your roller shutter or roller shades? This tubular motor selection chart helps you quickly determine the correct motor

Choosing the right motor is essential for ensuring smooth operation, long service life, and energy efficiency. To help our customers make faster and more accurate decisions, we have prepared a comprehensive motor selection chart.
This chart provides detailed specifications, including torque, speed, tube size compatibility, and voltage options, making it easier to compare different models side by side. Whether you are selecting a motor for residential roller shutters, commercial doors, or industrial applications, our chart gives you a clear guide to find the most suitable solution.
By using the tubular motor selection chart, you can:
Ensure better performance and durability of your roller shutter systems
Save time in choosing the right roller shutter motor
Compare technical parameters at a glance
Select motors based on application needs (residential, commercial, industrial)
Our goal is to provide reliable solutions that fit your project requirements.
Before you use this selection chart
- select your tube diameter and type( round or octagonal)
- Select the torque rating according to the total weight of the roller shutter
- a safety factor has already been taken into account
- match the motor to the tube
- Calculate the total weight of the roller shutter
How to Calculate Roller Shutter Motor Torque
Torque calculation formula:
Weight = Width × (Height + 0.2m) × Weight per m²
Based on the calculated weight, you can select the appropriate tubular motor torque from the chart above.
- Average weight of 40mm Foam filed Aluminium slats: 4.5kg/M2
- Average weight of 55mm Foam filed Aluminium slats: 6kg/M2
If you are new to this field, you can first understand what is a tubular motor before selecting the right model.

Roller blinds motor torque calculation
For roller blinds motor torque calculation: CHOOSE THE RIGHT ROLLER BLINDS MOTOR TORQUE
What torque tubular motor do I need?
- 👉 Lower torque motors (10–20Nm) are suitable for small roller shutters
- 👉 Medium torque (30–50Nm) fits standard residential use
- 👉 High torque (60Nm+) is recommended for heavy-duty industrial shutters
- For different applications, selecting the right motor is essential.
- For heavy-duty applications, check our roller shutter motor solutions.
- For lighter applications such as indoor shading, explore our roller blinds motor options.

FAQ:
Q1: How do I choose the right tubular motor?
Select based on shutter weight, width, and tube size using the selection chart.
Q2: How is motor torque calculated?
Torque depends on total shutter weight and lifting force required.
Q3: What torque is needed for roller shutters?
Small shutters: 10–20Nm, medium: 30–50Nm, large: 60Nm+.
Q4: Can I use the same motor for blinds and shutters?
No, blinds require lower torque motors than shutters.
Q5: What happens if torque is too low?
The motor may not lift the shutter properly and could be damaged.
Q6: How do I calculate tubular motor torque?
Torque is calculated based on shutter weight, width, and lifting requirements.
Q7: What happens if I choose the wrong motor torque?
Too low torque may cause failure to lift; too high torque may damage the system.
