Overview

The Ti5 ROBOT CRA-RI60-70-PRO Motor is a lightweight joint module designed for compact robotic joints where high torque density and precise feedback are required. It integrates key joint components such as the encoder, control board, motor stator/rotor, and harmonic reducers into a modular structure.

Key Features

  • Lightweight, compact joint module: Small size design for space-constrained robotic joints.
  • Ultra-lightweight concept: Stated reduction in weight by more than 1/3, helping reduce operating energy consumption.
  • Stronger performance (stated): Industrial-grade performance standards; stated torque density is twice that of similar products.
  • Modularization: Six modules are described as interoperable; three series are described as adaptable for different scenarios, supporting improved production efficiency.
  • Integrated joint structure: Motor back cover, control board, encoder, stator housing, motor rotor, motor stator, harmonic reducers, and flexspline cover.
  • Mass production advantage (stated): Underlying hardware described as controllable; a complete software toolchain is described for robot development and R&D acceleration.
  • Torque density comparison graphic: Chart title shown as “Comparison of torque density of mainstream joint products (Nm/kg)” with values shown: 250+ (Ti5 Robot Next Generation), 254 (An American brand), 192 (Ti5 Robot mass production model), 80.4 (A Chinese brand), 53.5 (A Canadian brand), 33.8 (A Korean brand).
