RJSII series joint modules-for industrial applications

The RJSII series joint modules are the second generation of RJS joint modules launched by Techservo to solve the needs of industrial robots, medical, military, aerospace, and other applications.

Explore and innovate security cooperation
• The new design structure has better heat dissipation performance and can be applied to the working scene of -20 ℃ -50 ℃
• The output is more powerful and the average load torque is larger, which can be used in the robotic 15-20kg payload
• With better waterproof and dustproof performance, protection grade IP54 (IP64 optional), suitable for more demanding industrial environments

RJSII series joint modules-Seiko quality, originality

Solve the adaptability and stability of robots in more complex work environments

New upgrade, exquisite craftsmanship, high cost performance

Comprehensive performance improvement, higher positioning accuracy, larger output torque, smoother and safer operation.

Traditional friction brake

Efficient braking Safe and reliable
• The traditional friction brake is used for better braking effect and safety.
• Excellent safety braking, anti-collision, instant locking.
• Compact structure, low noise, high safety, long life.
• Small torque fluctuations can instantly brake the load even when abnormal.

Driver

Intelligent drive, efficient and accurate
• Support EtherCAT / CANopen optional.
• High performance full digital servo driver, maximum power 1KW.
• Ultra-thin integration, smooth operation and fast response.
• Dual encoder feedback for precise control and robot dynamics development.

Motor

Hollow ultra-thin strong output
• Large hollow frameless motor, torque 0.2-5N.m, speed 2000-4000RPM.
• The total weight of the fixed rotor is only 0.27kg, which minimizes joint weight.
• Minimal torque ripple, low moment of inertia, and fast dynamic response.
• High accuracy, precise positioning, and 50% increase in output power.

Dual encoder

Keep improving
• High-precision dual encoder for precise control of motion trajectory beyond imagination.
• Hollow large aperture, ultra-thin design, more compact structure.
• Motor end incremental encoder resolution 20000P/R.
• End-point absolute encoder resolution 17bit, repeatability ± 0.015 °.
• Support BISS protocol.
