JUXIE INTELLIGENT CE-HM-R120 Series Robot Motor, 48 V, 51:1/101:1/161:1, up to 600 Nm peak, dual encoders, EtherCAT/CAN

Overview

JUXIE INTELLIGENT CE-HM-R120 Series is a high-torque Robot Motor platform for humanoid and mobile robotics. The series offers multiple gear configurations (51:1, 101:1, 161:1) and a high-power CE-HM-R120Max variant. It integrates dual encoders (19-bit single-turn) and an EtherCAT/CAN driver with 50KHz current loop and 10KHz speed loop. Typical use cases include shoulder, hip, and waist joints in humanoid robots and robotic arms, with compact dimensions R120*78.5mm or R120*100mm and overall weight from 2.5kg to 4kg.
