無(wú)刷電機(jī)直接驅(qū)動(dòng)離心機(jī)是由電機(jī)帶轉(zhuǎn)子高速旋轉(zhuǎn)的。過去的電機(jī)是帶碳刷的直流電機(jī),離心機(jī)運(yùn)轉(zhuǎn)時(shí)碳刷磨損,帶來(lái)火花與噪聲甚至振動(dòng),且有壽命,屆時(shí)要更換碳刷再行運(yùn)轉(zhuǎn)。更嚴(yán)重的是碳刷的磨損帶來(lái)碳粉塵的污染,不僅污染離心機(jī),還會(huì)污染周圍環(huán)境,這種污染對(duì)衛(wèi)生行業(yè)是不合適的。
當(dāng)轉(zhuǎn)子高速旋轉(zhuǎn)時(shí),空氣摩擦生熱,轉(zhuǎn)子溫度會(huì)上升,試管中的樣品溫度也會(huì)升高。由于生物學(xué)樣品對(duì)溫度敏感。一般要求離心實(shí)驗(yàn)中溫度保持4℃。沒有電腦控制的智能化技術(shù),是不可能做到這樣精度的。因此,用制冷機(jī)對(duì)離心腔冷卻,而達(dá)到冷卻轉(zhuǎn)子、冷卻樣品溫度的目的。但測(cè)量旋轉(zhuǎn)中的轉(zhuǎn)子的實(shí)際溫度極為困難,都采用在離心腔底部離轉(zhuǎn)子較近處埋設(shè)溫度傳感器,間接測(cè)量轉(zhuǎn)子溫度。血型離心機(jī)Ｔ補(bǔ)償又與轉(zhuǎn)子的類別、轉(zhuǎn)速及運(yùn)行時(shí)間有關(guān)。
無(wú)刷電機(jī)離心機(jī)性能：
以前模擬技術(shù)典型的表現(xiàn)形式為旋鈕選擇操作參數(shù)(如轉(zhuǎn)速、溫度與時(shí)間等),以表盤的指針來(lái)顯示數(shù)據(jù)?，F(xiàn)在運(yùn)用數(shù)字技術(shù),典型的表現(xiàn)形式為界面友好、鍵盤操作、數(shù)字化顯示、可編程操作的全電腦控制,其核心為智能化控制,是由電腦來(lái)實(shí)現(xiàn)的。離心機(jī)操作所需要一切參數(shù)(如轉(zhuǎn)速、溫度、時(shí)間、加減速率檔等),鍵盤操作輸入,并以數(shù)字顯示出來(lái),因此選擇操作參數(shù)與讀取數(shù)誤差極小。其缺點(diǎn)為:選擇參數(shù)與數(shù)據(jù)的讀數(shù)值受操作人與讀數(shù)人的人為干擾多,控制精度差。而且每次操作都要這樣,重復(fù)性差。有的離心機(jī)雖數(shù)字顯示(如旋鈕選值而數(shù)字顯示),雖在讀數(shù)上有改進(jìn),但取值原理未變?nèi)詫倌M技術(shù)又由于是可編程操作,可把一組操作參數(shù)編成號(hào)碼,可存取使用。

1 科學(xué)調(diào)整
直流機(jī)電作發(fā)電運(yùn)行時(shí)，電樞由原念頭驅(qū)動(dòng)而在磁場(chǎng)中旋轉(zhuǎn)，在電樞繞組的兩根有用邊中感應(yīng)出電動(dòng)勢(shì);而當(dāng)電念頭運(yùn)行時(shí)，將直流電源接在兩電刷之間而電暢通流暢進(jìn)電樞繞組，其工作原理基本分歧。發(fā)機(jī)電的電磁轉(zhuǎn)矩是阻轉(zhuǎn)矩，它與電樞轉(zhuǎn)動(dòng)的標(biāo)的目的或原念頭的驅(qū)動(dòng)轉(zhuǎn)矩的標(biāo)的目的相反;而電念頭的電磁轉(zhuǎn)矩則是驅(qū)動(dòng)轉(zhuǎn)矩，它使電樞轉(zhuǎn)動(dòng)，有著本質(zhì)的區(qū)分。是以，電念頭的電磁轉(zhuǎn)矩必需與機(jī)械負(fù)載轉(zhuǎn)矩和空載消耗相平衡。一般來(lái)說，當(dāng)軸上的機(jī)械負(fù)載發(fā)生變化時(shí)，則電念頭的轉(zhuǎn)速、電動(dòng)勢(shì)、電流和電磁轉(zhuǎn)矩將自動(dòng)進(jìn)行調(diào)整，以順應(yīng)負(fù)載的變化，連結(jié)新的平衡。但當(dāng)電念頭使用時(shí)間較長(zhǎng)或受負(fù)載發(fā)生急劇變化時(shí)，應(yīng)當(dāng)進(jìn)行人工調(diào)整，以避免負(fù)載突然加年夜或失衡，致使電念頭長(zhǎng)時(shí)間運(yùn)行而損壞。
