## Size a joint

- [Motor torque calculator](/tools/motor-torque-calculator?solve=power&t=30&n=60): **188 W** of shaft power at its rated 30 N·m and 60 rpm.
- [Robot arm torque calculator](/tools/robot-arm-torque-calculator?L=0.4,0.35,0.12&m=1.2,0.8,0.3&a=0.66,0.5,0&p=2): **32.6 N·m** at the shoulder with its 660 g at the elbow of a 2 kg-payload arm.
- [Humanoid robot actuators](/guides/humanoid-robot-actuators#waist): **4 of 7 joints** within its rated torque, up to the waist at 16.9 N·m.

## Use cases

- robot arm
- humanoid joint
- exoskeleton
- quadruped leg

## Robots that use it

- [BIG YAM](https://actuatorlist.com/robots#i2rt-big-yam) by i2RT Robotics: Heavier-payload 6-DOF variant. Uses DM6248 motors at the shoulders with substantially different control gains and a reversed joint 2; the only YAM whose SDK gains differ meaningfully from Standard.

## Notes

76mm OD x 62.5mm planetary joint motor with integrated driver and crossed-roller output bearing (the P suffix), the shoulder motor of the i2RT BIG YAM. 30 N.m rated, 97 N.m peak, 40 rpm rated, 48:1. No-load 60 rpm at 24V and 115 rpm at 48V; 11.3A rated and 38.7A peak phase current. DAMIAO manual V1.4 lists ~660g (AIFITLAB lists 628g). CAN with MIT, speed and position modes. $265 is the AIFITLAB price for the motor alone.
