电机绕组/定子的环氧树脂浇注密封工艺

Motor Winding/Stator Epoxy Resin Potting & Encapsulating

几乎所有的电机在工作时都不可避免面对升温，震动和离心力的影响，这些负面因素长期累积会造成绕组松动和绝缘材料老化，进而导致匝间和线间因摩擦带来的绝缘破坏，对电机的稳定性和寿命带来负面影响。

The impact of temperature rise, vibration, and centrifugal force are faced by almost all motors during operation. The accumulation of these negative factors over time will cause winding loosening and insulation material deterioration, which in turn will lead to insulation damage due to friction between coils and wires, negatively affecting the stability and working life of the motor.

绕组浸漆工艺已沿用多年，但针对应用场景复杂和高可靠性要求的电机，这种工艺显然并不足够，特别是受水，油，腐蚀性化学气体或粉尘等物质时，绝缘材料的寿命会大打折扣。

For many years, it was common to varnish the stator windings to achieve insulation. However, such varnishes do not fulfill the requirements of more demanding motors and more complex environments. In addition, their working life will be greatly reduced when facing materials such as water, oil, corrosive chemical gases, and dust.

一种提高电机工作稳定性和寿命的工艺是使用聚合物浇注密封电机绕组，环氧树脂是最常用的物料。坚固且绝缘的环氧树脂将绕组或铁芯包裹在内部，起到固定和抗震的作用，同时也让这些零部件与环境中的 “有害物质”隔离。具有高导热性能的Epoxy还能够帮助绕组将热量传导到外界从而保证电机整体的温度更加稳定。

One process to improve the operating stability and life of motors is to encapsulate the motor windings with polymer, and epoxy is the most common material for this purpose. The strong, insulating epoxy encases the windings or cores inside, providing anchoring and shock resistance while keeping these parts isolated from "harmful" substances in the environment. The high thermal conductivity of epoxy also helps the windings to conduct heat to the external environment, thus ensuring a more stable overall motor temperature.

浇注密封的工艺在今天已经很普遍，在诸如伺服电机，力矩电机，直线电机，水泵，油泵等等上都能够看到这种应用。 WILKON在这一领域具有丰富的经验，向有需要的客户提供高性价比的解决方案。WILKON推向市场的物料在开发前充分考虑到电机的结构，组装工艺和最终的工作状况，这些物料大部分具有以下特点：
