霍爾元件是應(yīng)用霍爾效應(yīng)的半導(dǎo)體。一般用于電機(jī)中測定轉(zhuǎn)子轉(zhuǎn)速，如錄像機(jī)的磁鼓，電腦中的散熱風(fēng)扇等；是一種基于霍爾效應(yīng)的磁傳感器，汕頭電動(dòng)車霍爾元件推薦，已發(fā)展成一個(gè)品種多樣的磁傳感器產(chǎn)品族，并已得到普遍的應(yīng)用。 </p> <p> 霍爾元件是一種基于霍爾效應(yīng)的器件，它可以見到到磁場的變化，這個(gè)特性使得它應(yīng)用普遍。我們以滑蓋手機(jī)為例，當(dāng)手機(jī)蓋側(cè)的磁鐵靠近手機(jī)側(cè)的霍爾元件時(shí)，會(huì)產(chǎn)生霍爾電壓，然后進(jìn)行放大給手機(jī)的CUP處理，比如關(guān)閉屏幕等動(dòng)作。我司是專業(yè)的霍爾元件生產(chǎn)廠家。華芯晟霍爾元件是質(zhì)量的霍爾元件生產(chǎn)廠家，汕頭電動(dòng)車霍爾元件推薦，廠家直銷，汕頭電動(dòng)車霍爾元件推薦，庫存充足，十七年專業(yè)做霍爾值得信賴！汕頭電動(dòng)車霍爾元件推薦</p><div

線性霍爾和開關(guān)式霍爾可以通用嗎？在轉(zhuǎn)把上用的霍爾元件，我們把它叫線性霍爾元件。就是說，根據(jù)磁場感應(yīng)的大小，它的電壓會(huì)隨著磁場大小的變化而變化，磁場感應(yīng)的強(qiáng)度越強(qiáng)，翰出的霍爾電壓就越大；磁場感應(yīng)的強(qiáng)度越小，翰出的電壓就越小。所以我們在轉(zhuǎn)動(dòng)轉(zhuǎn)把時(shí)，電壓可以從由小到大，逐漸加大，或者是逐漸變小。在電機(jī)上用的霍爾元件，我們把它叫做開關(guān)式霍爾元件。在磁場靠近霍爾元件時(shí)，這是霍爾元件直接導(dǎo)通狀態(tài)，輸出比較大電壓。磁場感應(yīng)離開時(shí)，直接進(jìn)入關(guān)閉狀態(tài)，沒有電壓輸出。就像個(gè)開關(guān)一樣的，保持通斷的功能。不能像轉(zhuǎn)把霍爾元件那樣，逐步的施加電壓。所以這兩種霍爾元件，因?yàn)榉诺奈恢貌煌?，所涉及的原理也不太一樣，所以它們是不能互相代?徐州低功耗霍爾元件霍爾元件廠家,一站搞定,提供高質(zhì)量產(chǎn)品服務(wù)霍爾元件廠家華芯晟精選各類霍爾元件,提供高質(zhì)量產(chǎn)品服務(wù)。</p><div

霍爾器件是一種對磁場強(qiáng)度起反應(yīng)的小型器件，只要它附近的磁場有變化它就有反應(yīng)并輸出相應(yīng)的電壓或脈沖電壓（開關(guān)型霍爾器件）。 </p> <p> 在用霍爾傳感器測量直流電動(dòng)機(jī)的轉(zhuǎn)速時(shí)，將一個(gè)小磁鐵塊固定在電機(jī)的轉(zhuǎn)子上，將霍爾傳感器（開關(guān)型）靠近小磁鐵附近，當(dāng)電機(jī)轉(zhuǎn)動(dòng)以后，磁鐵會(huì)以一定的周期靠近傳感器一次，這樣霍爾傳感器將輸出一個(gè)低電平，當(dāng)小磁鐵遠(yuǎn)離傳感器時(shí)，傳感器輸出一個(gè)高電平。將這個(gè)脈沖送到單片機(jī)內(nèi)部定時(shí)器，計(jì)算出脈沖一個(gè)周期的時(shí)間，就可以算出電機(jī)的轉(zhuǎn)速。 </p><p> <br /> </p> <p> 霍爾元件在電冰箱中的應(yīng)用： </p> <p> 冰箱霍爾開關(guān)常用來檢測冰箱門的開關(guān)狀態(tài)，冰箱中有兩個(gè)磁鐵兩個(gè)霍爾開關(guān)和一個(gè)電機(jī)是冰箱門的主要組成部分之一，把冰箱霍爾開關(guān)跟磁鐵分開固定在冷藏門跟冷凍門中，使冰箱霍爾開關(guān)跟磁鐵相對，根據(jù)冰箱霍爾開關(guān)靠近或離開時(shí)產(chǎn)生高低電壓來判斷冰箱開關(guān)，當(dāng)達(dá)到設(shè)定時(shí)間沒有關(guān)閉時(shí)候會(huì)通過控制系統(tǒng)給出使用者提示。冰箱門上用的霍爾一般用單極霍爾，如我司的HX6286,HX6278,HX6287等。冰箱電機(jī)里一般用鎖存型霍爾元件，如我司的HX41F-H,HXS41H,HX6571,HX6572,HX6573,HX6574等霍爾元件新春大促中~華芯質(zhì)量霍爾元件，多年行業(yè)好評，質(zhì)量好，價(jià)格優(yōu)，長期與多加**企業(yè)合作。</p><div

src="http://tyunfile.71360.com/UploadFile/wxhxskj/637082098600371094/3436331.jpg"></div><p> 如何判斷單極開關(guān)型霍爾元件是否有損壞？ </p> <p> 比如說，單極開關(guān)霍爾元件為5V接通，輸出端子的輸出電阻為串聯(lián)。當(dāng)磁體遠(yuǎn)離開關(guān)霍爾元件時(shí)，開關(guān)霍爾元件的輸出電壓為高電平(5V)。當(dāng)磁體接近(通常為S極)單極霍爾開關(guān)元件時(shí)，開關(guān)霍爾元件的輸出電壓較低(約0.2V)，說明開關(guān)開型霍爾元件性能良好。如果霍爾開關(guān)的輸出電平保持不變，就無法識別磁鐵接近或離開霍爾開關(guān)，則霍爾開關(guān)損壞。單極霍爾元件起到的就是開關(guān)功能，通過感應(yīng)磁場靠近或者原理來輸出低電壓或者高電壓，如果電壓不變，這個(gè)霍爾就已經(jīng)被損壞了。華芯多年專業(yè)做霍爾,大品牌值得信賴,精選各類霍爾元件,好評如潮,庫存充足!霍爾元件一站搞定,價(jià)格優(yōu)惠!連云港低功耗霍爾元件哪家好</p><p
