Tubular Motor vs Central Motor: Which Is Better for Roller Shutters?

Introduction

Tubular motors and central motors are two common solutions used in roller shutter automation systems.

Although both types of motors are designed to control the opening and closing movement of roller shutters, their structures, installation methods, and suitable applications are different.

Choosing between a tubular motor and a central motor depends on several factors, including shutter size, load requirements, available installation space, and expected operating frequency.

For installers, distributors, and project suppliers, understanding the differences between these two motor solutions helps create more suitable roller shutter automation systems.

Understanding Tubular Motors

Tubular motors are compact motor solutions designed to be installed inside the shutter tube.

Because the motor is integrated into the roller tube structure, the complete system can maintain a relatively simple and space-saving design.

How Tubular Motors Work

A tubular motor operates by rotating the shutter tube to raise and lower the shutter curtain.

When the control system sends an operating command, the motor generates rotational force that turns the tube and moves the shutter upward or downward.

The motor, limit settings, and control components work together to achieve controlled movement and accurate stopping positions.

Common Applications of Tubular Motors

Tubular motors are widely used in applications where compact installation and convenient automation are important.

Common applications include:

• Residential roller shutters

• Window shutters

• Small commercial shutters

• Awnings and similar automation systems

Because of their compact structure, tubular motors are often suitable for smaller and medium-sized shutter systems where installation space is limited.

Advantages of Tubular Motors

One of the main advantages of tubular motors is their simple and integrated design.

Since the motor is installed inside the tube, it requires less external installation space and provides a cleaner appearance.

Tubular motors can also support different control methods, including wall switches, remote controls, and smart automation systems, depending on the system configuration.

Understanding Central Motors

Central motors are another common solution for roller shutter automation, especially in applications requiring higher load capacity.

Unlike tubular motors, central motors are usually installed at the center of the shutter shaft and connected with the mechanical structure through a drive system.

How Central Motors Work

A central motor provides rotational force through a central drive mechanism to move the shutter curtain.

During operation, the motor transfers power to the shaft, allowing the shutter to open and close smoothly.

Because the motor is positioned externally rather than inside the tube, central motor systems can provide stronger driving capability for larger shutter applications.

Common Applications of Central Motors

Central motors are commonly used in applications where higher performance and stronger load handling are required.

Typical applications include:

• Commercial roller shutters

• Industrial shutters

• Larger entrance shutters

• Heavy-duty access systems

For larger shutters with higher operating demands, central motors can provide reliable performance when properly matched with the complete system.

Advantages of Central Motors

The main advantage of central motors is their ability to handle larger and heavier shutter systems.

Compared with compact tubular solutions, central motors are often selected for applications where higher torque output and stronger mechanical capability are required.

They are commonly used in commercial and industrial environments where shutters may operate frequently and require more durable automation solutions.

Tubular Motor vs Central Motor: Key Differences

Tubular motors and central motors both provide automated movement for roller shutters, but their designs make them suitable for different applications.

Understanding the differences between these two solutions helps installers and suppliers choose the right motor based on actual project requirements.

Installation Method

The installation method is one of the most noticeable differences between tubular motors and central motors.

Tubular motors are installed inside the roller tube, creating a compact and integrated structure. This design helps save space and provides a cleaner appearance, making them suitable for applications where installation space is limited.

Central motors are installed separately from the tube and connected through the shutter drive system. Although they require more installation space, this structure allows them to provide stronger mechanical performance for larger shutter systems.

Load Capacity and Application Range

Load requirements are another important factor when comparing these two motor types.

Tubular motors are commonly used for smaller and medium-sized shutters where compact design and efficient operation are priorities.

Central motors are generally more suitable for larger shutters that require higher torque and stronger driving capability. They are often selected for commercial and industrial applications where shutter size and operating frequency are higher.

The correct choice depends not only on shutter weight but also on factors such as shutter dimensions, mechanical structure, and expected workload.

Maintenance and Long-Term Reliability

Maintenance requirements can also influence motor selection.

Tubular motors offer a compact design with fewer external components, which can simplify installation and provide a neat system structure.

Central motors are often used in demanding environments where durability and load performance are more important. With proper installation and maintenance, they can provide reliable operation for larger automated shutter systems.

For both motor types, regular inspection of mechanical components and control systems helps maintain long-term performance.

How to Choose Between Tubular Motor and Central Motor

Selecting the right motor requires evaluating the complete roller shutter application rather than focusing on motor type alone.

The most suitable solution depends on shutter size, installation conditions, operating frequency, and performance requirements.

Residential Roller Shutter Applications

For residential applications, tubular motors are often a practical choice because they provide compact installation and convenient automation.

Residential shutters usually have lower operating frequency and smaller dimensions, making a compact motor solution sufficient for many applications.

However, the final selection should still consider shutter weight, available installation space, and user requirements.

Commercial and Industrial Roller Shutter Applications

Commercial and industrial environments often require stronger motor solutions due to larger shutters and more frequent operation.

For these applications, central motors may provide advantages because they are designed to handle higher loads and more demanding working conditions.

The selected motor should be evaluated together with the complete shutter system to ensure reliable performance.

Common Selection Mistakes

One common mistake is choosing a motor only based on price or basic power specifications.

A lower-cost solution may not provide sufficient performance if it does not match the shutter structure and operating conditions.

Another mistake is selecting a motor without considering future requirements. A shutter system that may experience increased usage in the future may require a more durable solution from the beginning.

Ignoring installation conditions can also create problems. The available space, shutter design, and mechanical structure should all be considered before making the final decision.
