AC/DC 风扇电机实现IP68的防护等级
AC/DC fan motors with a protection IP68 level
对于需要实现高于IP67防护等级的AC/DC风扇电机，使用环氧树脂浇注/密封绕组和控制PCB是目前最有效的解决方案。对于期望使用涂料浸渍来获得相同的防护等级并不现实，涂料浸渍只能实现防潮，潮湿与在水中浸泡是两种完全不同的应有场景。
For AC/DC fan motors that need to achieve a protection level higher than IP67, the most effective solution by far is to pot/encapsulate the windings with epoxies and control PCBs. It is not realistic to expect the same level of protection with dipping paint, which only provides protection against moisture. Mere moisture and immersion in water are two completely different scenarios.
AC/DC 电机采用环氧树脂浇注/密封的工艺存在一些难点：
Difficulties do exist when it comes to potting/encapsulating AC/DC motors with epoxy resin:
● 因尺寸小和尺寸精度要求高，大部分的环氧树脂难以在狭小的内部间隙中顺利完成灌封，如果客户同时要求树脂具有高的导热性能，随之带来的粘度上升会让灌封工艺变得更加困难。
The size is small and the requested dimensional accuracy is high. Most epoxy resins have difficulty completing potting in narrow gaps. If the customer also requires the resin to be of high thermal conductivity, the consequent increase in viscosity will make the potting process even more difficult.
● AC/DC风扇电机的市场特点决定只有实现高效的批量生产才能够获利，意味着模具的装配到环氧树脂的灌封到脱模都不能过于复杂，且要能够迅速完成。
The feature of the AC/DC fan motor market dictates that only efficient mass production can be profitable, which means that the assembly of the mold, the encapsulation of the epoxy resin, and the mold's release must not be too complicated and must be done quickly.
可以看到，模具的设计和环氧树脂的合理选择是解决问题的关键。模具的排气路径要合理，需要充分考虑到环氧树脂在流动特性和真空下的“反应”。环氧树脂在导热性能满足客户要求的前提下，需要具备低混合粘度和容易脱泡的特点。一旦掌握这些要点，大部分存在的困难能够顺利解决。
As you can see, the design of the mold and the reasonable selection of the epoxy resin are the key to the problem. The exhaust path of the mold should be reasonable, taking into account the flow characteristics and the "reaction" of the epoxy resin under vacuum. The epoxy resin needs to have a low mixing viscosity and be easy to de-bubble while its thermal conductivity meets the customer's requirements. Once these points are mastered, most challenges will not be difficult to solve.
