What Adhesives for Humanoid Robots? Selection Guide for Joint Motors, Magnets and Sensors
Common electronic adhesives for humanoid robots mainly include thermal conductive potting compounds, structural adhesives, thermal conductive gels, silicone gels, conformal coatings and sealants. One single material cannot fit all positions. For joint‑motor stators, thermal conductivity, insulation and mechanical fixation are critical. For magnet bonding, high‑temperature adhesion and vibration resistance are essential. Power devices such as MOSFETs require thermal‑interface materials with low thermal resistance. Torque / pressure sensors are best protected by low‑stress silicone gels. Control PCBs generally adopt conformal coatings for moisture‑proof and insulation protection. For these applications, ELAPLUS provides electronic functional‑material solutions including EP 1715 (2#), EP 1769, SIPA 1850, TCMP series, FSGEL 3200, COATING 9060 UV and others. 1. Why Do Humanoid Robots Need Electronic Adhesives? Humanoid robots are highly integrated with frameless torque motors, reducers, drivers, AI computing modules, torque sensors, encoders, control PCBs, batteries and wiring harness systems. During walking, running, jumping, handling, emergency stop and frequent direction switching, internal electronic and mechanical components are continuously exposed to: Accordingly, electronic adhesives for humanoid robots serve six core purposes:thermal conduction, electrical insulation, structural bonding, potting protection, vibration damping and moisture‑proof sealing. The higher the robot’s motion performance, the less designers should rely merely on initial bond strength or single thermal‑conductivity values. Thermal cycling, vibration, shock, fatigue and property retention after long‑term aging must also be evaluated. 2. Which Adhesive for Humanoid‑Robot Joint‑Motor Stators? Recommended: Thermally conductive epoxy potting compound The stator of a humanoid‑robot joint motor requires potting materials delivering thermal conduction, electrical insulation and mechanical fixation.In frameless torque motors, copper windings continuously generate heat. Large air gaps between windings and metal housings severely degrade heat dissipation efficiency. Potting establishes a heat‑transfer path:Windings → Potting Material → Motor Housingwhile mechanically locking the coils in place. Recommended Model: ELAPLUS EP 1715 (2#)EP 1715 (2#) is a two‑component thermally…
