## Size a joint

- [Motor torque calculator](/tools/motor-torque-calculator?solve=power&t=0.75&n=4150): **326 W** of shaft power at its rated 0.75 N·m and 4150 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=0.248,0.5,0&p=2): **31 N·m** at the shoulder with its 248 g at the elbow of a 2 kg-payload arm.

## Use cases

- robot arm
- exoskeleton
- quadruped leg

## Notes

Motor. R-series torque motor (housed/framed with bearings + Hall sensors), dia 73.8 x 23 mm. Peak torque 2.3 Nm at 28A peak; rated torque 0.75 Nm at ~8.5A; no-load speed ~5520 rpm; 351 W. The bare-frameless equivalents are the RO60 outrunner and RI60 inrunner. Needs an external FOC driver (e.g. ODrive/moteus). Km 0.171 Nm/sqrt(W).
