Electromate is now offering the new High-Efficiency Joint (HEJ) series—a compact, integrated actuator solution developed to meet the demanding performance needs of mobile and manipulation robots. The HEJ Series HEJ 90 and HEJ 70 actuators are engineered for use in legged robots (including quadrupeds and bipeds), autonomous mobile manipulators, compact robotic arms, and wearable systems such as exoskeletons. Each unit features integrated joint control electronics with 1 kHz loop cycles, sensor feedback, and active thermal management. Built-in heat sinks and high-load output bearings (cross-roller type) enhance reliability for outdoor, dynamic, or mobile use cases. With onboard control, torque sensing, and EtherCAT daisy-chaining capabilities, the HEJ series reduces the number of external components and cables required, enabling system integrators to speed up development and simplify system complexity.
