The JRM-C Planetary Joint Module is a lightweight, high-torque actuator module specially designed for humanoid robots, wheeled robots, quadruped robots, and other intelligent robotic systems.
By deeply integrating a high power-density frameless motor, planetary reducer, high-precision encoder, and integrated driver, the module achieves a more compact structure, smaller size, high torque output, and lightweight design.

HONPINE’s self-developed drive algorithms ensure high compatibility between the joint module and the robot body, enabling highly coordinated operation and significantly improving motion synchronization and control performance.
At the same time, the module is designed to meet the robotics industry’s demands for high customization, rapid development cycles, flexible configuration, and fast market responsiveness.
Features of the JRM Planetary Joint Module
Full-series outer diameter coverage from 42 mm to 150 mm, with peak torque support up to 600 Nm.
Equipped with HONPINE’s self-developed fourth-generation high torque-density motor for powerful performance output.
High rigidity under heavy loads with stable long-life operation.
Plug-and-play quick-connect design for easier and more reliable wiring.
