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 utilisation and excellent performance. 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 utilisation and excellent performance. Equipped with a large hollow through-hole structure it supports centralised 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 standardised 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 drives.
