Details
SITO DRIVE TA-40 is a compact rotary actuator built for highly integrated robot joint modules.
Integration combines a harmonic reducer, frameless torque motor, drive electronics, dual encoders, and an optional brake.
Compact form factor helps maximize torque density when space is limited in joint designs.
Measured power under rated conditions is kept below 30 W, supporting efficient joint actuation.
Wide temperature tolerance supports deployment from low-temperature environments through high-heat operation.
Long working life is rated up to 7000 hours for sustained robotics duty cycles.
Control modes and development support include host software, documentation, and an SDK for Windows and Linux.
Designed for joint actuation in humanoid robots, robotic arms, exoskeletons, quadrupeds, and mobile robots.
AI-ready underlying hardware platform concept for a range of robotics applications.
