With the rapid development of AI, industrial automation, and intelligent manufacturing, robots have penetrated into every corner of our lives and industries
Four legged robots run on inspection sites, collaborative robotic arms precisely assemble mobile phone chips, exoskeleton equipment helps rehabilitation patients walk again
These seemingly futuristic scenes have become reality
With the continuous evolution of robots towards lightweight, high-precision, and intelligent collaboration, joint motors, as the “driving core”, are facing multiple challenges in power density, heat dissipation, and reliability. Material breakthroughs have become the key to improving its performance.
Frameless torque motor – the central power of efficient robot systems
Frameless Torque Motor is designed specifically for high-performance robots and industrial automation. With its advantages of compact structure, light weight, and strong output, it is gradually replacing the traditional combination of “reducer+servo motor” and becoming the new generation of power core.
The electromagnetic system has been optimized and designed to increase torque and power density by up to 25%, meeting the urgent demand for high-efficiency output in lightweight systems. Internally integrated Hall and temperature sensors, combined with advanced encapsulation technology, ensure excellent heat resistance and long-term stability even in high temperature environments, while achieving precise control and real-time monitoring.
Behind the technical difficulties lies the material bottleneck
Electromagnetic efficiency is no longer the only pursuit, “structure+thermal management+reliability” is the new generation competitiveness of robot joint motors.
Soft magnetic materials under high power are prone to saturation and suffer from significant eddy current losses;
The thermal expansion stress caused by extreme temperature differences affects the lifespan of electronic components;
Difficulty in heat dissipation under a closed shell and the threat of moisture intrusion to system safety;
The cogging torque causes low-speed shaking, which affects the cooperation accuracy;
Under long-term operation, bonding/sealing materials are prone to aging and cracking.
EP 1720- Creating a Robot Core Power Safety Barrier
To cope with the extreme working conditions faced by robot joint motors, ELAPLUS has launched EP 1720 two-component flexible epoxy sealant. This material is designed specifically for low stress protection and high temperature aging resistance, with excellent crack resistance and long-term electrical stability.
