## Size a joint

- [Motor torque calculator](/tools/motor-torque-calculator?solve=power&t=360): **360 N·m** peak; add a speed for its shaft power.
- [Humanoid robot actuators](/guides/humanoid-robot-actuators): **7 joints** with a static torque estimate and the catalog parts that reach it.

## Use cases

- humanoid joint
- quadruped leg
- heavy arm

## Notes

High-torque internal-rotor PMSM joint used across the Unitree H1 / H1-2 humanoid. Unitree publishes no standalone motor spec table. The 360 N.m peak is Unitree's robot-level 'knee torque about 360 N.m' (H1 also lists hip ~220, arm ~75, ankle ~59 N.m; H1-2 arm 120 N.m), not a motor rating. Unitree also states a 189 N.m/kg peak torque density for H1 without giving the motor mass. The previous 1900 g weight was inferred from 360/189 and is removed, since Unitree does not publish it. Weight, gear ratio, rated torque, speed, voltage and price are not published for the bare motor (sold as part of H1). Unverified: no manufacturer weight or ratio.
