Description
The 52mm Harmonic Drive Integrated Joint HJ2-52 is an integrated joint module for compact, high-precision motion axes. It combines motor, drive/reducer, and encoder functions in one modular unit and is part of a platform available in 52, 70, 80, 90, and 110 mm sizes. The family is designed for applications such as humanoid robots, collaborative robots, industrial robots, machine tools, and industrial automation.
Key technical strengths focus on compact integration, control precision, and industrial connectivity. The ultra-thin design reduces volume by 20%, while dual heat dissipation supports reduced heat generation. A built-in 24-bit high-resolution encoder enables closed-loop precision control, and support for EtherCAT/CANFD provides compatibility with high-speed industrial buses and open protocols. Long-life harmonic drives and ultra-long endurance are specified for durable operation, with brake-equipped versions available.

Within the 52 mm family version, the listed variants provide 11 N·m peak torque and 5 N·m rated torque. Encoder resolution is 24-bit, and unit weight is 326 g for HJ2-52H101D24-NK-EC and 380 g for HJ2-52H101D24-BK-EC. For HJ2-52H101D24-NK-EC, the data also specifies 65% overall weight reduction, 25% heat generation reduction, 2x torque density increase, and EtherCAT/CANFD bus support.
