霍爾元件電子剎把改為機(jī)械剎把：機(jī)械剎把兩根線中的一根與信號(hào)線連接，另一根與負(fù)極線連接。不使用紅色5伏。其原理是機(jī)械剎把將兩根導(dǎo)線連接到控制器內(nèi)部三極管的集電極和負(fù)極（以常用的NPN電子開(kāi)關(guān)電路為例）。集電極上是控制器速度信號(hào)通過(guò)的地方，即一旦機(jī)械剎把開(kāi)關(guān)閉合，速度信號(hào)被旁路到地面（負(fù)極）。低電平：剎車(chē)線控制器對(duì)外輸出電壓信號(hào)路過(guò)剎把開(kāi)關(guān)，關(guān)閉后信號(hào)倒地，剎車(chē)動(dòng)作。高電平：將電壓信號(hào)輸入控制器的剎把線，打開(kāi)控制器中的電子開(kāi)關(guān)，剎車(chē)動(dòng)作。 </p><p> 霍爾元件在電風(fēng)扇中的應(yīng)用： </p> <p> 電風(fēng)扇的主要部件是：雙線圈直流馬達(dá)電機(jī)其工作原理是帶電線圈在磁場(chǎng)作用下旋轉(zhuǎn)。能量轉(zhuǎn)換的形式是：電能主要轉(zhuǎn)化為機(jī)械能，同時(shí)由于線圈具有電阻，部分電能不可避免地轉(zhuǎn)化為熱能。 </p> <p> 風(fēng)扇中的霍爾開(kāi)關(guān)主要用于雙線圈直流電機(jī)驅(qū)動(dòng)。風(fēng)扇中的霍爾開(kāi)關(guān)也可用于CPU冷卻風(fēng)扇和直流冷卻風(fēng)扇。該風(fēng)扇霍爾開(kāi)關(guān)工作電壓低，聲音很低，并且風(fēng)扇霍爾開(kāi)關(guān)的穩(wěn)定性非常穩(wěn)定，與其他傳感器兼容。一般使用鎖存型霍爾元件，如HX41F-H,HXS41H,HX6571,HX6572,HX6573,HX6574等我公司霍爾產(chǎn)品擁有超大庫(kù)存，可以快速發(fā)貨。每一箱霍爾產(chǎn)品都會(huì)在工廠備案，提供一對(duì)一完善的售后服務(wù)。</p><div
