WALTER MOTOR · Tubular Motor Manufacturer
Tubular Motor Manufacturer for Blinds, Shutters & OEM Projects
A tubular motor is a compact electric drive installed inside a roller tube to automate roller blinds, roller shutters, awnings, zip screens, projection screens and smart shading systems. For OEM buyers, distributors and project engineers, choosing the right drive is not only about torque. It also depends on tube diameter, voltage, limit system, control method, noise level, duty cycle, installation environment and long-term reliability.
Walter Motor is the international website and brand presentation of Zhejiang Walter Mech Electrical Co., Ltd., a professional motor manufacturer based in Jiaxing, Zhejiang, China. This guide explains how the drive works, how to compare 25mm, 35mm, 45mm and 59mm series, and how to select a suitable solution for blinds, shutters, awnings and customized OEM projects.

Why This Tubular Motor Guide Is Different
Many pages only explain basic definitions. This guide is written from a manufacturer’s point of view. A reliable motor solution must match the final application, tube profile, torque requirement, limit system, control method, accessory design, testing standard and after-sales expectation.
Tubular Motor Quick Selection Table
This table gives a practical starting point for motor selection. The final choice should also consider fabric weight, shutter material, tube diameter, crown and drive wheel size, control method, installation direction, usage frequency, wind load and safety margin.
| Application | Recommended Motor Size | Typical Torque Range | Recommended Walter Series |
|---|---|---|---|
| Small roller blinds and smart shades | 25mm | 0.8–1.5Nm | WM25 Series |
| Large roller blinds and medium shading systems | 35mm | 3–10Nm | WM35 / YYGL35 Series |
| Roller shutters, awnings and zip screens | 45mm | 10–50Nm | YYGL45 Series |

What Is a Tubular Motor?
A tubular motor is an electric drive designed to be installed inside a roller tube. It rotates the tube directly, allowing a blind, shutter, awning fabric, zip screen or projection screen to move up, down, open or close automatically.
Because the drive is hidden inside the tube, the final system looks clean and compact. This structure is widely used in homes, offices, hotels, commercial buildings, security shutters, sunshade systems and smart building automation.
For B2B buyers, the most important question is not only “what is a tubular motor?” but “which motor is suitable for this application?” A small indoor roller blind may only need a 25mm low-torque model, while a heavy roller shutter or large awning may require a 45mm or 59mm solution with much higher torque.

How Does a Tubular Motor Work?
The drive converts electrical energy into rotational motion. Inside the motor, the stator and rotor generate power, the gearbox reduces speed and increases torque, and the output shaft transfers rotation to the roller tube. When the tube turns, the blind, shutter, awning fabric or screen moves with it.
Main Internal Parts
- Motor core: generates rotational power.
- Gearbox: reduces speed and increases output torque.
- Limit system: controls upper and lower stop positions.
- Brake system: helps stop and hold the load.
- Output shaft: transfers rotation to the tube.
- Crown and drive wheel: connect the motor body to the roller tube.

Main Types of Tubular Motors
Tubular motors can be selected by power supply, limit system, control method and application. The best choice depends on the final product design and market requirement.
AC Motors
AC models are commonly used for roller shutters, awnings, large roller blinds, zip screens and heavy-duty shading systems. They are suitable for stable wired installations and higher torque applications.
DC, Battery and Solar Motors
DC, battery and solar drives are often used for roller blinds and retrofit smart shading systems where fixed wiring is difficult. They are suitable for residential windows, renovation projects and smart home applications.
Mechanical Limit Motors
Mechanical limit motors are simple, stable and cost-effective. They are widely used in standard roller shutters, awnings and basic shading systems.
Electronic Limit and Smart Motors
Electronic limit and smart drives can support more precise positioning, RF remote control, WiFi, Zigbee, app control or smart home integration depending on the model.

Applications
These motors are used in many roller tube-based systems. The correct size depends on application type, tube diameter, load, torque requirement, control method and installation environment.
Roller Blinds
Roller blinds usually use 25mm or 35mm drives. Small indoor blinds may use low-torque 25mm models, while larger blinds or heavier fabrics may require 35mm motors.
Roller Blinds Motor
Roller Shutters
Roller shutters usually require 45mm or 59mm motors because the load is heavier than normal fabric blinds. Torque selection must consider shutter material, width, height and tube size.
Roller Shutter Motor
Awnings and Outdoor Shading
Awnings usually need higher torque because the drive must handle fabric tension, arm structure, projection size and outdoor conditions.

How to Choose the Right Motor: 7 Key Tips
For OEM customers and project buyers, the best choice is not always the highest-torque product. It is the drive that correctly matches the application, tube, load, control method and long-term use conditions.
1. Confirm the Application
Different applications require different motor sizes and torque ranges. Roller blinds usually use 25mm or 35mm models, while roller shutters, awnings and heavy-duty systems usually require 45mm or 59mm motors.
2. Calculate the Required Torque
Torque must match the weight, width, tube diameter and operating load. An undersized drive may overheat, move unstably or reduce system lifetime.
3. Match the Tube Diameter
The motor, crown, drive wheel, bracket and tube profile must match correctly. Poor accessory fit can cause noise, vibration, unstable operation or installation failure.
4. Choose the Right Power Supply
AC motors are suitable for stable wired installations and higher torque applications. DC, battery and solar motors are suitable for retrofit blinds and smart window covering projects.
5. Select the Limit System
Mechanical limit motors are simple and cost-effective. Electronic limit models can provide more precise positioning and may support advanced functions depending on the configuration.
6. Confirm the Control Method
The drive can be controlled by wall switch, remote control, external receiver, built-in receiver, WiFi, Zigbee or smart home systems depending on product configuration.
7. Evaluate the Manufacturer
Quality depends on process control, winding consistency, gearbox durability, brake performance, limit switch reliability, aging tests, final inspection and after-sales support.
Manufacturing Reliability Behind the Product
For B2B buyers, the product is not only a specification. It is the result of material selection, production process control, assembly accuracy and testing consistency. Two motors may look similar from the outside, but the internal winding, gearbox, brake, limit switch and testing standards can be very different.
Walter Motor focuses on:
- Stator and rotor manufacturing control
- Motor winding consistency
- Gearbox matching and lubrication
- Brake stability for holding the load
- Upper and lower limit testing
- Noise, torque and speed consistency
- Final inspection before shipment
