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.<\/p>\n
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.<\/p>\n
Integrated motor, reducer, and encoder in one compact joint module
\n24-bit encoder for high-resolution closed-loop precision control
\nEtherCAT\/CANFD support for high-speed industrial bus communication
\nUltra-thin design with 20% volume reduction
\nLong-life harmonic drives with dual heat dissipation
\nWithin the 52 mm family version, the listed variants provide 11 N\u00b7m peak torque and 5 N\u00b7m 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. <\/p>\n","protected":false},"excerpt":{"rendered":"
