## Size a joint

- [Motor torque calculator](/tools/motor-torque-calculator?solve=power&t=0.59&n=420): **25.9 W** of shaft power at its rated 0.59 N·m and 420 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=0.428,0.5,0&p=2): **31.7 N·m** at the shoulder with its 428 g at the elbow of a 2 kg-payload arm.

## Use cases

- gimbal
- robot arm
- direct drive joint

## Notes

Motor. Large gimbal/direct-drive motor, 36N/42P, dia 89.5 x 33.4 mm, hollow shaft, weight 428g. Torque figures converted from published load torque (manufacturer quotes 6 kg-cm = 0.59 Nm; higher listings cite up to 9 kg-cm = 0.88 Nm); no-load current 0.3A, load current 2A, phase resistance 4.2 ohm. Low-Kv (80T) gimbal winding suited to low-speed direct-drive joints. Price is with-encoder variant (iFlight EU). Needs external FOC/gimbal driver.
