Description

車用發電機之繞線定子製作方法
本發明係相關於一種車用發電機之繞線定子製作方法,特指一種可提高發電機發電效率之新穎繞線定子的製作步驟。
定子為發電機內主要的軸心機構,藉由定子與轉子間之相互感應可達到令發電機產生感應電流之效。而現有技術繞線式車用發電機之定子製作上,為利用一定子環之T型爪片為繞組來進行漆包線之纏繞,以於定子環上層層繞上感應線圈。
然而傳統之繞線方式所製作之定子中,其繞線後所產生之銅損較高,且繞線後之漆包線之線端上暴露出之銅心部分較長,導致整體的銅損高,因此往往造成在產品性能上無法提升之窘境,且更容易帶來馬達作業時升溫之問題,此外,在現有技術之繞線手法中,線圈與線圈間之間距無法整齊,亦即線圈之疏密程度難以保持一致,因此漆包線之佔槽率容易因該繞線的間距不等而受影響,並進而減損發電機整體之發電效率。
為解決上述之現有技術不足之處,本發明目的在提供一創新之車用發電機之繞線定子製作方法,以改良現有技術中之效率問題。
本發明主要目的係在提供一種車用發電機之繞線定子製作方法,係包括:定子環成型步驟,其為利用定子環成型工法製作一定子環,其上環繞設有複數個呈輻散分佈之長型透孔,該透孔之總數量為三之倍數;銅線裁剪步驟,其為將斷面呈現矩形之漆包銅線裁剪成複數段長度相同之插線;彎線成型步驟,其為將複數長直之插線彎成U字型後,再進一步將U字型插線之圓滑彎曲處折合成V字型;除端線絕緣漆步驟,其為將彎折完畢之插線兩自由端之包覆絕緣漆切除;置設絕緣紙步驟,其為將對應透孔內環壁面之複數絕緣紙套對應穿設於定子環之每一透孔中;銅線插設步驟,其為將定子環之每一透孔自外而內分成第一至四等四等分,並將所有之插線均分為兩部,第一部之每一插線之一自由端對應插設於一透孔之第二等分處,其另一自由端以相同方向對應跨越五個透孔後插設於相鄰之第六個透孔中的第三等分處,且第二部之每一插線之一自由端對應插設於一透孔之第一等分處,其另一自由端以相同方向對應跨越五個透孔後插設於相鄰之第六個透孔中的第四等分處,而藉兩部之插線依序將所有透孔交織佈滿而形成一環繞之線圈結構,而插線之線端穿出透孔之另一端;加壓整線步驟,其為以一加壓機具從已插設妥之插線上端對各插線進行加壓,使其具有平整之表面並使突出於另一面之線端彼此齊平;端線扭線步驟,其為自線端穿出透孔處將第一部之插線的線端朝相同之一切線方向作彎折,並再將線端處彎折使其朝透孔外向延伸,此外並將穿出透孔之第二部插線的線端朝與第一部之插線彎折向相反的切線方向作彎折,並將線端處彎折使其朝透孔外向延伸,同時令第二部插線位於第一等分處之線端對應於一第一部插線位於第二等分處的線端且該兩線端並排鄰設,此外令第一部插線位於第三等分處之線端對應於一第二部插線位於第四等分處的線端且兩線端並排鄰設;端線焊接步驟為將各第一、二部之插線彎折後相鄰並排之線端作焊接,使原本相互成斷路之分離插線形成一相連並成迴圈之線路。
利用本發明所製作之定子具有能有效降低銅損之特徵,可以在產品性能上得到提升,並解決馬達於作業時升溫快速之問題,此外,由於插線與插線間交織慎密且整齊,因此可有效率的控制線圈之疏密程度,並且達到提高佔槽率之訴求,進而增加發電機整體之發電效率。
