MRS Series Rotary Joint Actuators

1. Product Introduction This rotary joint actuator highly integrates a high-precision hollow inductive encoder a high-performance frameless torque motor and a harmonic reducer balancing extreme space utilization and excellent performance. Equipped with a large hollow through-hole structure it supports centralized routing of wires to optimize system wiring. The full series includes five specifications of harmonic reducers (11 14 17 20 25) and its lightweight design is compatible with multiple joints of humanoid robots such as wrists elbows shoulders hips and waists. The standardized interface supports quick replacement of three reduction ratios (51/81/101) enabling a single platform to flexibly cover high-speed and high-torque requirements and meet core demands for joint drive. 2. Product Highlights ①Highly Integrated Design: Integrates three core components with a maximum torque density of 88Nm/kg adapting to the extreme space of robot joints and optimizing installation layout. ②Full-Scenario Compatibility: Five specifications of harmonic reducers combined with lightweight design accurately cover multiple robot joints featuring strong versatility without additional modification. ③High Precision and Stable Operation: Harmonic drive ensures gear backlash < 1arcmin with smooth transmission and low loss guaranteeing high precision and long service life of the driver. ④Flexible Adaptability: Quick switching of three reduction ratios allows a single platform to meet both high-speed and high-torque needs reducing R&D and procurement costs. ⑤Systematic Optimization: The large hollow through-hole organizes wires solving wiring clutter and improving the convenience of system design. 3. Main Application Industries It is mainly applied in the humanoid robot industry and extended to high-end intelligent manufacturing precision automation and special robot fields suitable for scenarios requiring high precision and stability.
