AC/DC FAN MOTOR USES EPOXY FOR CASTING/ENCAPSULATING AND OBTAINS IP67 OR IP68 RATINGAC/DC 風扇電機采用環氧樹脂澆注/密封實現IP67或IP68防護等級

對于需要實現防水,即達到IP67防護等級的AC/DC 風扇電機來講,使用環氧樹脂澆注/密封繞線組和PCB是目前最有效的解決方案。

For AC/DC Fan Motor which requires water protection (ie IP67 or IP68), the use of Epoxy to potting / encapsulate the winding group and PCB is the most effective solution currently.

在過去的案例中,我們看到一部分客戶期望通過使用三防材料涂層讓風扇電機達到IP67防護等級,但這種方案僅僅能夠讓風扇電機達到防潮而不是防水。薄而且強度有限的涂層一旦被水浸泡,將很快被分解和破壞,最終失去保護功能。潮濕與泡水對電氣產品來講是兩種程度不同的環境影響因素。

In the past cases, we saw that some clients would like to make Fan Motor to obtain IP67 even IP68 rating by using coating, but this will only allow Fan Motor to keep away from moisture rather than water. Once the coating which is thin with limited strength is immersed in water, it will soon be broken down and destroyed, and ultimately lose protection. Moisture and soaking in water are two different degrees of environmental factors for electrical products.

AC/DC 風扇電機采用環氧樹脂實現澆注/密封的工藝主要存在以下兩方面的難點:

There are two difficulties for AC/DC Fan Motor to use Epoxy to achieve the Epoxy casting / encapsulating process:

首先,大部分風扇電機的尺寸很小,尺寸精度要求高。風扇電機內部存在很多狹小的間隙,大部分的環氧樹脂難以順利澆注灌封,如果客戶需要環氧樹脂具有高導熱性能,這要求將提高環氧樹脂的粘度,讓灌封變得更困難。

First of all, most of the Fan Motor size is very small with high requirements on dimensional accuracy. Fan Motor has a lot of small gaps inside, and most of the Epoxy is difficult for potting. If the client requires Epoxy with high thermal conductivity, it’ll increase the viscosity of Epoxy, making potting more difficult.

其次,AC/DC 風扇電機的市場特點決定只有實現高效的批量生產才能夠獲利,意味著模具的裝配到環氧樹脂澆注灌封都不能過于復雜,否則會導致產品成本過高。

Secondly, AC/DC Fan Motor's market characteristics determine that only efficient batch production can be profitable, meaning that it cannot be too complicated from mold assembly to Epoxy potting, otherwise it will lead to excessive product cost.

我們可以看到,解決問題的關鍵在于模具的設計和環氧樹脂的合理選擇。模具的排氣路徑要合理,需要充分考慮到環氧樹脂在流動階段下的特點和真空下的“反應”。Epoxy在導熱性能滿足客戶要求的前提下,需要具備低混合粘度和容易脫泡的特點。一旦掌握這些要點,大部分存在的困難能夠順利解決。

We can see that the key to solving the problem lies in the design of the mold and reasonable choice of Epoxy. The exhaust path of the mold should be reasonable, and Epoxy’ characteristics in the flow phase and its "reaction" under vacuum condition should be taken full account of. Epoxy requires a low mixing viscosity and easy defoaming under the premise that its thermal conductivity meets client’s requirements. Once you master these points, most difficulties can be resolved successfully.
