An AC tubular motor is a compact electric motor designed to fit inside the tube of a roller blind, rolling shutter, or similar window covering. It turns the tube to raise or lower the covering, while a compatible control system and limit settings manage movement and stopping positions. To choose the right motor, match its torque, speed, tube dimensions, power supply, control method, and operating conditions to the finished product—not just to the covering’s weight.

This guide is for importers, manufacturers, project buyers, and distributors evaluating AC tubular motors for doors and window accessories. At Yozewit, we help buyers organize these requirements before discussing suitable product options. Because motor specifications and compatibility vary by model, buyers should confirm all dimensions and operating details with the supplier before placing an order.
The motor is installed inside a compatible roller tube, leaving the drive assembly largely concealed within the window covering or shutter system. When powered, it rotates the tube and moves the attached fabric, slats, or other covering material. A suitable control and limit arrangement determines how the motor starts, stops, and responds to user commands.
“AC” refers to the motor’s alternating-current power supply. It does not, by itself, define the motor’s control method, limit-setting mechanism, noise level, or compatibility with a particular tube. These details must be checked in the model-specific documentation.
Some AC tubular motors are designed for wired control, while other configurations may include or work with a compatible radio receiver. The right choice depends on the control system planned for the installation and whether the buyer needs local switches, remote operation, or integration with another control platform. Confirm the control interface and any required accessories as part of the complete system specification.
Limit settings define the upper and lower stopping positions. Depending on the motor design, these may be adjusted mechanically or through an electronic system. Buyers should check how settings are made, whether they can be changed after installation, and what instructions are needed by installers.
Tubular motors are offered in different body diameters and drive configurations to suit different roller tubes and product designs. A motor that fits the internal tube diameter may still be unsuitable if its crown, drive adapter, bracket, or overall length does not match the installation. Ask the supplier to confirm the motor-to-tube fit using drawings or the relevant dimensions rather than relying on a diameter label alone.
Technical values are useful only when they describe the intended application. For example, a project may use 230 V AC as its stated supply requirement, specify 10 Nm as a preliminary torque target, or request a speed near 17 rpm. These figures are examples of specification units, not recommendations or claims about a standard Yozewit model; confirm the actual values for the selected motor.
| Specification | Why it matters | What to confirm |
|---|---|---|
| Supply voltage and frequency | Determines whether the motor is suitable for the installation’s electrical supply. | Required voltage, frequency, wiring, and any regional variation. |
| Rated torque | Indicates the motor’s turning capability for moving the selected covering. | Required torque for the full assembly and the manufacturer’s selection guidance. |
| Rotational speed | Affects how quickly the tube turns and the covering moves. | Rated speed and whether it suits the project’s operating expectations. |
| Motor diameter and length | Influence installation fit within the tube and available space. | Body dimensions, adapters, brackets, and usable installation clearance. |
| Duty and protection information | Help buyers assess operating limits and environmental suitability. | Model-specific duty guidance and any stated protection rating. |
| Control and limit system | Determines how the motor is operated and how end positions are set. | Control compatibility, adjustment method, and included accessories. |
For interior blinds, start with the fabric or covering dimensions, tube size, mounting arrangement, and the way the product will be controlled. Consider whether the motor’s speed and limit system fit the user experience and installation process. If the design uses a particular control platform, confirm compatibility before finalizing the motor selection.

For shutters, assess the complete assembly rather than selecting a motor from shutter dimensions alone. Slat type, tube geometry, guides, installation conditions, and operating frequency can affect the load placed on the motor. For exterior applications, verify the supplier’s stated environmental and duty information for the exact model, and do not assume that all AC tubular motors are suitable for exposed or demanding conditions.
Awnings and other coverings may have different loads and installation requirements from indoor blinds. Buyers should share the product type, dimensions, tube details, control requirements, and expected use with the supplier. Where the finished assembly has unusual geometry or operating demands, request a technical review instead of applying a rule of thumb.
The price of an AC tubular motor can depend on its specification, control configuration, accessories, order quantity, packaging, and shipping terms. There is no reliable universal price or minimum order quantity to apply across all models and suppliers. Request a quotation based on the exact configuration and quantity you need.
Lead time can also vary with product availability, customization, production planning, and destination requirements. Ask the supplier to state the estimated production and dispatch schedule, the quotation validity, payment terms, and what could affect timing. If the project has a fixed delivery date, raise it before confirming the order.
A dependable sourcing decision requires more than comparing headline prices. Check whether the supplier can provide model-specific technical documentation and explain the selection basis for your application. Ask how dimensional compatibility, accessories, installation instructions, and any stated operating limitations will be confirmed.
One frequent mistake is choosing a motor by torque alone without checking tube fit, control compatibility, or the complete assembly. Another is assuming that motors with the same diameter are interchangeable, even though drive components and mounting arrangements may differ. Buyers can reduce these risks by submitting the full application specification and obtaining written confirmation before ordering.
It is also risky to treat an illustrative value as a product guarantee or to assume that one motor configuration suits every market. Confirm electrical requirements for the destination and verify any project-specific requirements with the supplier and relevant installation professionals. If a requirement is not stated in the product documentation, ask for clarification rather than making an assumption.
The right AC tubular motor is the one that fits the tube and installation, meets the electrical and control requirements, and is suitable for the complete covering assembly. Begin by documenting the application, dimensions, supply, control method, expected operating conditions, and target quantity. Then ask suppliers to confirm the model-specific specifications, compatibility, quotation terms, and estimated lead time in writing.
At Yozewit, we work with B2B buyers in doors and windows accessories to clarify requirements and discuss suitable sourcing options. Share your application details, drawings or tube dimensions, control preferences, destination market, and order volume to start a focused inquiry. This gives us a practical basis for reviewing the motor requirements and preparing a relevant quotation.
