Selection note
Stall torque is a short-duration limit for product comparison, not a continuous operating point. Allow suitable margin for duty cycle, temperature, impact, acceleration and mechanism friction.
Selection and use¶
- Confirm the product label and document revision match this page.
- Confirm the permitted supply range from this model’s formal documentation before selecting a regulated supply; a single catalog voltage does not establish a range. Size current for simultaneous operation.
- Match the controller, wiring and SDK to the listed interface and product family.
- Check mounting space, output shaft, travel and mechanical clearance before enabling torque.
For communication commands and software integration, continue with the SDK guide and the protocol documentation for this product family.

Request resources or report an issue¶
Use your existing FEETECH technical-support contact and include the full label/model suffix, firmware version (if known), and the document revision you are using.
- Software: controller/OS, SDK version or commit, adapter/interface, supply voltage, confirmed ID/baud rate (bus models only), minimal reproduction and logs.
- Mechanics: drawing/CAD revision, marked dimensions, required travel, horn/bracket, load and lever arm, duty cycle, and the point of interference.
- Missing files: name the exact item in the resource table (for example, this model's STEP and a dimensioned mounting drawing).
This package currently provides a specification summary and integration checklists. File availability does not imply that your firmware, load case or assembly has been validated.
