Description of Harmonic Drive Robot Joint Motor
Based on the standard harmonic joint motor with a single encoder, this version adds a brake to further ensure the safety, stability, and control performance of the robot joint.
In the event of an emergency power-off or system shutdown, the brake automatically locks the joint, preventing the robotic arm from falling and thereby protecting both personnel and equipment.
In applications such as industrial robots and collaborative robots, joint modules equipped with a brake are more compliant with safety standards and provide greater operational convenience.

Brand Introduction
HONPINE has been manufacturing harmonic reducers since 2018. Although it started relatively late, it has progressed rapidly thanks to the support of a professional and experienced technical team. Soon after, it began producing harmonic joint modules, harmonic rotary actuators, planetary joint modules, and other products. It was one of the first Chinese companies to begin testing in the European and American markets. Its products are mainly used in humanoid robots, semiconductor equipment, medical equipment, industrial automation, collaborative robots, and industrial robots.
