## Size a joint

- [Motor torque calculator](/tools/motor-torque-calculator?solve=power&t=40&n=150): **628 W** of shaft power at its rated 40 N·m and 150 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=1.485,0.5,0&p=2): **35.8 N·m** at the shoulder with its 1490 g at the elbow of a 2 kg-payload arm.
- [Humanoid robot actuators](/guides/humanoid-robot-actuators#ankle): **5 of 7 joints** within its rated torque, up to the ankle at 38.4 N·m.

## Use cases

- robot arm
- humanoid joint
- quadruped leg

## Notes

MIT-driven integrated joint motor with built-in 10:1 reduction and dual 14-bit magnetic encoders; MIT (impedance/torque), position and velocity modes; CAN 1 Mbps control, UART tuning. Spot-checked against the DAMIAO manual V1.0 (2024-05-19) specifications table: rated 40 N.m, peak 150 N.m, 10:1, rated 100 rpm, max no-load 150 rpm, 48 V rated (24-48 V supported), rated 20 A, peak 70 A, about 1485 g, 112 mm OD (120 mm max outline) x 62 mm. Torques are listed for the geared unit; the manual does not say 'output shaft' explicitly, but the 100/150 rpm speeds only fit output-side values at 10:1. Not to be confused with the DM-J10010L-2EC. No DAMIAO product page for this model on damiaokeji.com; price is Foxtech's (authorized distributor, USD).
