Electromate Introduces the maxon HEJ Series in Canada: Compact, High Torque Robot Joints for Robotic Applications

Electromate Introduces the maxon HEJ Series in Canada

Electromate, Canada’s exclusive distributor of precision mechatronic components from maxon, 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 90 and HEJ 70 units combine maxon’s core competencies—brushless motors, gearboxes, encoders, and motion controllers—into sealed joint actuators ready for harsh, real-world applications.

Product Highlights 

HEJ90 

  • Delivers up to 140 Nm peak torque (180 Nm optional) 
  • Max joint speed: 13 rad/s 

HEJ70 

  • Delivers 50 Nm peak torque 
  • Max joint speed: 28 rad/s 

Key Benefits 

  • High output powers, well-coolable 
  • Dynamic motions and high peak torques 
  • Efficiencies up to 86% 
  • IP67 ingress protected 
  • Integrated electronics and joint output bearing 
  • Ideal for Mobile Autonomous Robots: Humanoids, Quadrupeds, and Mobile Manipulators 

These 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.
