🔥 What Is a Tubular Motor? 7 Powerful Facts You Must Know
What Is a Tubular Motor?
This type of motor is a compact electric motor designed to be installed inside a cylindrical tube, primarily used to automate systems such as roller blinds, roller shutters, awnings, and zip screens. Its unique tubular shape allows it to fit seamlessly inside the roller shaft, making it an efficient and space-saving solution for modern automation.
If you are new to this technology, you can explore our full range of tubular motors for roller blinds and shutters to better understand different models and applications.
Unlike traditional motors that are externally mounted, tubular motors are hidden within the tube, offering a cleaner appearance, quieter operation, and better protection from dust and external damage.
Today, This type of motors are widely used in both residential and commercial environments due to their durability, reliability, and compatibility with smart control systems.

How Does a Tubular Motor Work?
This type of motor works by converting electrical energy into mechanical rotation.
When the motor is powered on, the internal rotor rotates within the stator, generating motion. This motion is transferred through a gearbox, which reduces speed while increasing torque. The output shaft then rotates the roller tube, causing the blind, shutter, or awning to move.
Most tubular motors are equipped with an integrated limit switch system, allowing users to set upper and lower stopping points. This ensures precise positioning and automatic stopping without manual intervention.
👉 This mechanism makes tubular motors ideal for automated shading systems.
7 Key Components Inside a Tubular Motor
Understanding the internal structure helps you select the right motor.
For example, smaller systems often use a 25mm motor, while larger applications may require more powerful models.
1. Stator
The stator is the stationary part of the motor that generates a magnetic field when electricity flows through it.
Learn more about stator
2. Rotor
The rotor rotates inside the stator, converting electromagnetic energy into mechanical motion.
Learn more about rotor
3. Gearbox
The gearbox reduces rotational speed and increases torque, enabling the motor to handle heavier loads such as shutters.
4. Limit Switch
This component controls the upper and lower limits of movement, ensuring accurate stopping positions.
5. Motor Head
The motor head connects the motor to the mounting bracket and power supply system.
6. Output Shaft
The output shaft transfers rotational force to the roller tube.
7. Brake System
The brake system prevents unintended movement when the motor stops, especially important for safety.
Types of Tubular Motors
It comes in different types depending on application requirements.
AC Tubular Motor
Operate on standard mains voltage (100–240V). They deliver higher torque and are preferred for heavy-duty applications such as large commercial roller shutters or industrial doors.
DC Tubular Motor
Run on low voltage (12–24V), often powered by rechargeable batteries or solar panels. They excel in quiet operation and seamless integration with smart home ecosystems.
Smart Tubular Motor
Smart motors support advanced control options such as WiFi, Zigbee, remote control, and app integration. They are widely used in modern smart homes.
Additional functional variants include:
- Motors with manual override for emergency hand-crank operation during power failures.
- Models equipped with mechanical limit switches (cost-effective and durable) versus electronic/encoder-based limit switches (precise positioning and obstacle detection).
- Radio-controlled or Wi-Fi-enabled versions for remote and app-based control.
As of 2026, the market increasingly favors smart tubular motors compatible with voice assistants and IoT platforms, reflecting growing demand for connected home solutions.
Common Applications of Tubular Motors
Tubular motors are widely used across different industries:
- Roller blinds (residential and office use)
- Roller shutters (sunshade, security and industrial use)
- Awnings (outdoor shading systems)
- Garage doors
- Projection screens
Their versatility makes them a key component in automation and smart building solutions.
How to Choose the Right Tubular Motor ⭐
Choosing the correct motor is critical for performance and longevity.
1. Tube Diameter
Different tube sizes require different motor diameters:
- 25mm → Small roller blinds
- 35mm → Standard blinds and small roller shutters.
- 45mm → normal roller shutters
- 59mm → Heavy duty roller shutters
2. Torque (Nm)
Torque determines lifting capacity:
- 6–10Nm → Light fabrics
- 10–20Nm → Medium blinds
- 20Nm+ → Roller shutters
3. Application Environment
Indoor systems require quieter motors, while outdoor systems require waterproof and durable designs.
4. Control System
Choose between manual switch, remote control, or smart control (WiFi/Zigbee).
