About this product

DM-JH14-51-2EC is a DAMIAO integrated harmonic robot-joint actuator with a 51:1 reduction ratio, a hollow central bore, dual encoders and an integrated drive. The manufacturer publishes 5.4 N m rated output torque and 18 N m peak torque, with 40 rpm rated output speed; permitted peak duration is unspecified. It has a nominal 24 V rating and supports 24–48 V supplies, CAN FD communication up to 5 Mbps, and UART parameter tuning. The manufacturer assigns the cover photograph to its JH14 page containing both reduction-ratio models; the photograph does not establish the internal ratio. An exact release date is not verified. Cover image: Manufacturer series image; size may vary.
