Açıklama
This is the joint actuator Unitree builds into its Z1 6-axis robot arm, supplied as a separate part for teams that run Z1 arms and need a replacement or a spare joint. It combines the motor with a harmonic reducer and an industrial-grade crossed roller bearing in a compact Φ65 × 52 mm housing weighing 405 g.
Unitree rates it at 33 N·m maximum torque with about 6 arcmin of backlash and a reduction ratio of 60 and above. A 15-bit encoder and a 1 kHz control frequency over RS-485 support the arm's force control, with a force-control accuracy of about 0.2 N·m. The motor reports torque, angle and angular velocity, and accepts torque, angle, angular velocity, stiffness and damping commands; 24 V is the recommended supply.
These joints give the Z1 its position-plus-force control and collision detection, and they also explain a trait Unitree is open about: because the reduction ratios are relatively low, the arm's position-control stiffness is low, and without an optimised control mode it can show position error and shake in motion. Which of the arm's six joints the part fits, whether it suits your Z1 Air or Z1 Pro, and the replacement procedure are confirmed in writing with your quotation.

Sıkça Sorulan Sorular
That is confirmed with your quotation. Tell us your arm version, Z1 Air or Z1 Pro, and the joint you need to replace, and we confirm the fit before you order.
33 N·m maximum torque, about 6 arcmin of backlash, a harmonic reducer with a 60+ ratio, a 15-bit encoder, about 0.2 N·m force-control accuracy and 1 kHz control over RS-485, at 405 g and Φ65 × 52 mm.
The Z1's joints use relatively low reduction ratios, which keeps them suited to force control but makes position-control stiffness low. Without an optimised control mode the arm can show position error and shake, so control tuning matters after any joint work.
The replacement procedure for your arm version is confirmed with the quotation, and technical support is coordinated through the manufacturer's service network.
The Unitree Z1 Joint Motor is priced at 129.995 Ft in your market.
