Harmonic Drive Frameless Torque Motor Precision Encoder Rotary Actuator
● Introduction
It features a multi-turn absolute encoder with Tamagawa protocol: single-turn 23-bit, multi-turn 16-bit. The actuator can be directly mounted via the end face, making it ideal for lightweight or space-constrained applications.
Features
The modular design highly integrates the harmonic drive, frameless motor, and encoder.
Volume can be reduced by 30–50%
Weight can be reduced by 20–40%
● High Torque Density
The transmission structure minimizes energy loss, efficiently converting motor power into mechanical output at the shaft.
● High Precision
Based on harmonic drive principles, the flexspline and circular spline engage over multiple teeth with minimal backlash. Coupled with a high-precision encoder, it enables accurate position and motion control.
● Rigidity and Shock Resistance
The solid shaft has uniform material distribution, providing excellent torsional and impact resistance. It maintains minimal deformation under high-frequency reciprocating loads or sudden shocks, ensuring stable transmission.
● Compact Structure
The simplified design eliminates redundant flanges, reducing size and weight while maintaining structural integrity.
