Sealing, potting, thermal management

Linear and rotary actuators

Actuators, consisting of components such as encoders, motors, servo drives, and force sensors, require potting and sealing to withstand vibration, shock, and mechanical loads and to be protected against environmental influences, as well as thermal protection to prevent thermal drift.

Sealing, thermal management

Battery

Sealing and thermal management protect cells and ensure battery safety, performance, and longevity.

Encapsulation

Tactile hand

The tactile incorporates encoders, motors, and sensors and requires protective encapsulation. This safeguards sensitive electronics from vibration, impact, repetitive mechanical loads, dust, and moisture, while preserving sensing accuracy and long-term durability.

Potting

Vision

Potting is used to encapsulate the LiDAR and camera modules in humanoid robot vision systems, providing mechanical stability, vibration damping, and protection against dust, moisture, and thermal stress while maintaining sensor alignment and performance.

Sensors and lidar systems are used to ensure the robot's safety, reliability, and efficiency

Potting

Electric motor

Potting of e‑motors protects against environmental influences, improves vibration resistance, and reduces thermal stress critical for compact, high‑torque joints. At the same time, stabilizing and protecting the copper windings helps prevent short circuits and increases stator rigidity.
