快(kuai)速(su)(su)門一般是由電機(ji)來推動運作的，而在快(kuai)速(su)(su)門上所安裝的電機(ji)也(ye)分成(cheng)(cheng)很多種(zhong)多樣，其品質也(ye)不盡相同。快(kuai)速(su)(su)門電機(ji)有(you)鋁線電纜包(bao)的及其銅心線包(bao)的，而用(yong)(yong)鋁線電纜包(bao)的電機(ji)成(cheng)(cheng)本費比較便宜，電機(ji)的使用(yong)(yong)期不久(jiu)，缺陷許多且(qie)非(fei)常(chang)容易燒毀(hui)：

  1、鋁線電(dian)纜的(de)(de)電(dian)阻高，因此繞阻的(de)(de)電(dian)阻測量(liang)大，所造成(cheng)的(de)(de)發熱(re)量(liang)也(ye)更大。

   2、鋁(lv)線電纜的傳熱工作能力比銅心線低，不容易熱管散(san)熱。

  3、鋁線(xian)電纜的色澤比銅心線(xian)的軟，抗磁場的帶動工作能(neng)力和(he)抗機(ji)械設備的震動力都(dou)較為弱，因而線(xian)間與堵轉會造成磨擦，時間長了就非常(chang)容易毀壞。

  而(er)銅(tong)心線(xian)(xian)(xian)(xian)包(bao)的(de)(de)電(dian)(dian)(dian)(dian)機(ji)(ji)則(ze)不一(yi)樣。盡管用銅(tong)心線(xian)(xian)(xian)(xian)包(bao)的(de)(de)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)成(cheng)本費(fei)要比鋁(lv)(lv)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜包(bao)的(de)(de)電(dian)(dian)(dian)(dian)機(ji)(ji)高很(hen)多，可(ke)是用銅(tong)心線(xian)(xian)(xian)(xian)包(bao)的(de)(de)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)使(shi)(shi)用期要比鋁(lv)(lv)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜包(bao)的(de)(de)電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)使(shi)(shi)用期更(geng)長，更(geng)長的(de)(de)使(shi)(shi)用期另外也(ye)可(ke)以節省電(dian)(dian)(dian)(dian)機(ji)(ji)的(de)(de)成(cheng)本費(fei)。并且銅(tong)電(dian)(dian)(dian)(dian)磁線(xian)(xian)(xian)(xian)圈(quan)(quan)電(dian)(dian)(dian)(dian)機(ji)(ji)在運行(xing)那時(shi)候所(suo)(suo)造成(cheng)的(de)(de)發熱量要比鋁(lv)(lv)電(dian)(dian)(dian)(dian)磁線(xian)(xian)(xian)(xian)圈(quan)(quan)電(dian)(dian)(dian)(dian)機(ji)(ji)所(suo)(suo)造成(cheng)的(de)(de)少許多，換句話說銅(tong)電(dian)(dian)(dian)(dian)磁線(xian)(xian)(xian)(xian)圈(quan)(quan)電(dian)(dian)(dian)(dian)機(ji)(ji)更(geng)耐高溫和經久耐用。

  因(yin)而快速(su)門(men)電機要挑選品質更強的銅電磁線圈(quan)電機，那樣才可以確保(bao)快速(su)門(men)高頻、長期地平穩運作。
