Maxon has recently launched its latest addition to the company’s Excessive Efficiency Robotic Joints portfolio, a move that further solidifies its position as a leading manufacturer of high-performance robotic components. Maxon highlighted the novel demands for its advanced actuator units, emphasizing increased torque density and effectiveness. The HEJ 70-48-50 is designed to support a broad spectrum of autonomous cellular robots operating in uncharted environments alongside other devices, such as sensors, actuators, and controllers.
The HEJ 70-48-50 motor achieves a maximum torque of 50 Nm and attains speeds of up to 28 rad/s while weighing only slightly more than 1 kg. Maxon highlights the HEJ 70-48-50’s compact design and exceptional torque density, rendering it an ideal choice for cell manipulation tasks, offering roboticists a robust yet lightweight solution.
“The HEJ 70 marks a significant breakthrough in actuator innovation for dynamic robotics,” said Stefan Müller, Chief Technology Officer at maxon. What enables our clients to pioneer new frontiers in autonomous cellular robotics is our unique fusion of cutting-edge effectiveness and seamless technique harmonization within an incredibly agile and portable framework.
Maxon’s Excessive Effectivity Joints combine high-torque electrical motors, precision planetary gearing, intelligent electronics, advanced sensors, and assist structures to create ultra-compact, robust (IP67-rated), and EtherCAT-controlled robotic actuators. Embedded heat dissipation mechanisms and precision-engineered cross-roller bearing systems enable seamless fusion of advanced therapy methods.
Maxon is expanding its Excessive Effectivity Joint platform to further amplify its capabilities. Here is the rewritten text:
Currently, there are two techniques available: the HEJ 90, which offers 140 Nm of torque at a weight of 2 kg, and the HEJ 70, which provides 50 Nm of torque at a weight of 1 kg. | Credit score: maxon
The Maxon management system’s configurability enables flexible setup and accommodates various topological configurations for effective impedance management within the joint. While the compact HEJ 70-48-50 excels in cell manipulation and small robotics applications, its larger counterpart, the HEJ 90-48-140, is better suited for locomotion and propulsion methodologies. Maxon highlights key actuator options for autonomous cell robots: excessive robustness, low mechanical inertia, good backdrivability, and high efficiency?
Techniques utilizing deep reinforcement learning and associated simulation methods enable roboticists to develop high-performance and reliable robots that align with current design trends. Maxon suggests that swift-paced robotics companies should focus on their core robotics value drivers and hurdles, while Maxon tackles critical intricacies occasionally tied to robotics actuators, encompassing high-efficiency, reliability, supply chain management, integration, and testing considerations.
The HEJ 70-48-50 is slated to begin deliveries in the early part of second quarter 2025. Discover the comprehensive datasheet and learn more about how the HEJ 70-48-50 actuator can elevate your robotic operations by clicking here.
