Beschreibung
HJ2-70F101D24-BK-EC is a compact integrated robotic joint for high-precision motion axes. This 70 mm module combines motor, harmonic reducer, and 24-bit encoder in one unit, with a 101 reduction ratio and integrated field bus support. It is part of the HJ2 platform for humanoid robots, collaborative robots, industrial robots, machine tools, and industrial automation.
Key performance data include 9.6 Nm rated torque at 20 RPM, 34 Nm peak torque, 49 RPM peak speed, and 10 arcsec backlash. The joint operates on 48 VDC, with 3.6 A rated current and 5 A max current. Its built-in 24-bit encoder supports closed-loop precision control, while EtherCAT, CAN, and CANFD enable integration into high-speed industrial bus systems and open protocol environments.
- Integrated motor, reducer, and encoder for compact axis design
- 24-bit encoder for high-resolution closed-loop precision control
- Supports EtherCAT, CAN, and CANFD communication
- Ultra-thin modular design with 20% volume reduction and dual heat dissipation
- Brake version with long-life harmonic drive and ultra-long endurance
The unit has a 70 mm outer diameter, 12 mm inner diameter, 82.3 mm length, 800 g mass, and 125 g·cm² inertia. Additional electrical data include 0.47 Ω resistance, 0.215 mH inductance, 10 pole pairs, and a torque constant of 8.9 Nm/A. Speed is specified at 37 RPM at 4.8 Nm, and maximum allowable torque is 13.5 Nm.
