Frameless Torque Motor

The frameless torque motor features torque fluctuation under 1% and 3.5‑times overload capacity, providing stable, high‑performance torque output for robot joint applications.

Introduce

Ultra-Compact Direct Drive Motors for Robotics

Haozhi Frameless Torque Motors eliminate outer housings, bearings, and shafts to integrate stator and rotor directly into robot joints. Delivering <1% torque ripple and up to 3.5 times  peak overload capacity, they feature a hollow-shaft design for clean cable routing—maximizing power density while minimizing system size and weight.

Features

Engineered for Precision, Power Density, and Seamless Integration    

Designed specifically for collaborative and humanoid robot joints, Haozhi Frameless Torque Motors combine high torque output, precise motion control, and superior structural flexibility.

  • Ultra-Low Torque Ripple (<1%)  

    Ensures exceptionally smooth motion control, minimizing speed fluctuations and noise during high-precision joint movement. 

  • 3.5x Peak Overload Capacity

    Delivers robust dynamic response and high peak torque output to handle transient high loads and complex motion profiles. 

  • Housing-Free Frameless Architecture

    Eliminates extra housings and bearings, enabling direct embedding into joint housings and supporting large hollow-shaft designs for compact wiring.

Applications
