It combines motor, reducer, and encoder in one compact unit for high-precision motion axes in humanoid robots, collaborative robots, industrial robots, machine tools, and industrial automation. This version has a 101 reduction ratio, 48 VDC supply, 24-bit encoder resolution, EtherCAT\/CAN\/CANFD field bus support, 70 mm outer diameter, 61.3 mm length, and 598 g mass.  <\/p>\n<p class=\"paragraph\">  Key technical strengths focus on compact integration, precision control, and industrial communication. The integrated architecture reduces system complexity, while the built-in 24-bit encoder supports closed-loop precision control. Harmonic drive technology provides 10 arcsec backlash, with 9.6 Nm rated torque at 20 RPM, 34 Nm peak torque, 13.5 Nm max allowable torque, 64 RPM peak speed, and 52 RPM at 4.8 Nm. The platform also features an ultra-thin design with 20% volume reduction, dual heat dissipation, modular design, long-life harmonic drives, ultra-long endurance, and open protocol compatibility.  <\/p>\n<ul>\n<li>Integrated motor, reducer, and encoder in one module<\/li>\n<li>24-bit encoder for high-resolution closed-loop precision control<\/li>\n<li>EtherCAT, CAN, and CANFD support for industrial bus integration<\/li>\n<li>Low 10 arcsec backlash for precise motion<\/li>\n<li>Compact 70 mm diameter format within the HJ2 size platform<\/li>\n<\/ul>\n<p class=\"paragraph\">  The module is suited to compact robot joints and other precision axes where space, accuracy, and bus connectivity are critical. Electrical data includes 8 A max current, 2.3 A rated current, 0.37 \u03a9 resistance, 0.19 mH inductance, 10 pole pairs, and 5.6 Nm\/A torque constant. Mechanical data includes a 12 mm inner diameter and 100 g\u00b7cm\u00b2 inertia. The HJ2 family is available in 52, 70, 80, 90, and 110 mm sizes, with brake-equipped versions available in the platform.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Integrated 70 mm robotic joint module for compact, high-precision motion axes in humanoid, collaborative, and industrial robots.
