Overview
TLIBOT TSJA17 is a compact Robot Motor integrating a harmonic-drive joint, high-resolution absolute encoders, fieldbus interface, and an electromagnetic brake for precise robotic motion. It supports multiple harmonic reduction ratios and delivers high torque density for lightweight robotic mechanisms and collaborative robots.
Key Features
- Harmonic reduction ratio options: 50 / 80 / 100 / 120.
- Rated torque: 20 / 28 / 31 / 31 Nm; peak torque for start/stop: 44 / 56 / 70 / 70 Nm.
- Maximum allowable average load torque: 34 / 35 / 51 / 51 Nm; instantaneous allowable maximum torque: 91 / 113 / 143 / 112 Nm.
- Maximum rotational speed at the output end: 60 / 37.5 / 30 / 25 RPM.
- Motor rated speed: 3000 RPM; peak instantaneous motor speed: 4500 RPM.
- Rated voltage: 48 V; weight: 0.68 kg.
- Encoders: 19bit single-turn absolute (battery-less) at output; 19bit ST absolute (multi-turn via output, battery-less) at input.
- Fieldbus options: EtherCAT / CAN / CAN FD.
- Integrated gear-meshed electromagnetic brake.
- Per product images: IP54-rated joint structure with continuous 360° rotation; suitable for lightweight arms in the 5–10 kg payload, 500–1000 mm reach class.
- Axial mounting method illustrated for shell integration (see installation document).
