Home Industry Solutions AI Motor module
Motor module
The servo drive motor module needs to run continuously at high speed for a long time and continuously generates a large amount of heat. At the same time, it often faces complex working conditions such as dust, condensation, and alternating vibration. Its internal coils, power devices, and drive PCBA need to rely on the cooperation of three types of functional materials such as thermal conductive potting, conformal anti-paint, and thermally conductive interface materials to achieve core guarantees.
