Overview
TLIBOT TSJA20 is a compact Robot Motor designed for high-torque robotic joints. It integrates a harmonic reducer, dual high-resolution encoders, and a geared electromagnetic brake in a lightweight package, enabling precise motion control and continuous rotation for advanced robotic systems.
The module supports industrial fieldbuses (Ethercat/CAN/CAN FD), offers 48 V operation with 160 rated power, and delivers repeatable positioning of 1. Encoder architecture is battery-less for both output and input sides, simplifying maintenance and integration.
Key Features
- Harmonic reduction ratio options: 50 / 80 / 100 / 120
- Integrated gear-meshed electromagnetic brake
- Battery-less 19bit single-turn output encoder and 19bit ST input encoder (multi-turn via output)
- Industrial fieldbus support: Ethercat/CAN/CAN FD
- IP54-rated joint structure and continuous 360 rotation (as shown in product materials)
- Axial installation to the robot shell illustrated for fast integration
- Lightweight design at 0.98 Kg
