在用霍爾傳感器測量直流電動機的轉速時，將一個小磁鐵塊固定在電機的轉子上，江蘇HX163霍爾開關，將霍爾傳感器（開關型）靠近小磁鐵附近，當電機轉動以后，磁鐵會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低電平，當小磁鐵遠離傳感器時，傳感器輸出一個高電平，江蘇HX163霍爾開關。將這個脈沖送到單片機內部定時器，計算出脈沖一個周期的時間，就可以算出電機的轉速。華芯霍爾元件，江蘇HX163霍爾開關，質量霍爾元件，行業(yè)**霍爾元件，廠家直銷，質量有保障。江蘇HX163霍爾開關</p><div

手電筒霍爾元件的設計提供了內部控制時鐘機制，通過定期掃描提供給霍爾器件和模擬信號處理電路。電路的一部分用于“睡眠”模式下的高電流消耗。周期性地喚醒內部電路以根據霍爾元件的通量確定預定閾值。磁通中的密度低于或高于BOP/BRP閾值，則驅動輸出晶體管的相應狀態(tài)將改變，在睡眠周期期間，輸出晶體管被鎖定在先前狀態(tài)。手電筒霍爾元件它極大地延長了電池的使用壽命，以滿足客戶對低功耗系統(tǒng)的要求。一般使用全極微功耗的霍爾元件，如：如HX6383，HX6382,HX6363,HX6373等全極微功耗霍爾開關。中山HX6278霍爾開關價格無錫華芯霍爾開關是質量的霍爾開關供應商，連續(xù)17年專業(yè)做霍爾。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇HX163霍爾開關,霍爾開關"

線性霍爾和開關式霍爾可以通用嗎？在轉把上用的霍爾開關，我們把它叫線性霍爾開關。就是說，根據磁場感應的大小，它的電壓會隨著磁場大小的變化而變化，磁場感應的強度越強，翰出的霍爾電壓就越大；磁場感應的強度越小，翰出的電壓就越小。所以我們在轉動轉把時，電壓可以從由小到大，逐漸加大，或者是逐漸變小。在電機上用的霍爾開關，我們把它叫做開關式霍爾開關。在磁場靠近霍爾開關時，這是霍爾元件直接導通狀態(tài)，輸出比較大電壓。磁場感應離開時，直接進入關閉狀態(tài)，沒有電壓輸出。就像個開關一樣的，保持通斷的功能。不能像轉把霍爾開關那樣，逐步的施加電壓。所以這兩種霍爾開關，因為放的位置不同，所涉及的原理也不太一樣，所以它們是不能互相代。 </p><p> 霍爾開關在電動車中的應用 </p> <p> 霍爾開關在電動車速度控制開關中的作用：旋轉手柄的旋轉角度由霍爾開關轉換為可變數字電壓到可變數字電壓，以便為控制器提供調節(jié)的目的。一般使用線性霍爾開關來實現該功能，如HX6649,HX6659,HX6639等線性霍爾開關 </p> <p> 其次，霍爾開關在電動汽車電機中的作用：霍爾開關在電動汽車電機中的主要作用是改變相電流的方向，用來代替電機的電刷，所以使用霍爾開關的電機必須是無刷電機。一般使用鎖存型霍爾開關如HX41F,HXS41H,HX6571等 </p> <p> 霍爾開關在電動車輛斷開制動中的作用：斷開制動的霍爾開關是將制動時產生的磁場強度變化轉化為數字電壓，為電機提供動力啟動剎車裝置。一般使用單極霍爾開關如HX6286,HX6278,HX6287等。華芯十六年專業(yè)做霍爾元件,****!霍爾元件一對一方案設計,快速交貨,完善的售后服務體系!</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="江蘇HX163霍爾開關,霍爾開關" src="http://tyunfile.71360.com/UploadFile/wxhxskj/637128652396113282/8184245.jpg"></div><p> 霍爾開關時使用注意事項（上） </p> <p> 1.霍爾是敏感器件，在使用過程以及存儲過程中應注意采取靜電防護措施。 </p> <p> 2.適宜的電源電壓和負載電路及工作溫度是霍爾器件正常工作的先決條件，霍爾器件的供電電壓，負載電流及工作溫度不得超出規(guī)格書中多規(guī)定的范圍。 </p> <p> 3.所用工具，特別是焊接用的電烙鐵，必須嚴格接上地線，以保證電烙鐵不漏電，即電烙鐵的鐵皮是接地的，比較好選用低壓恒溫可調電烙鐵進行焊接。 </p> <p> 4.所有設備都應嚴格接地，并用檢電筆逐個查明確無漏電，才能開始工作。 </p> <p> 5.要求印制板及霍爾器件管腳嚴格經過清潔處理，使它與焊錫有良好的浸潤性。華芯全極霍爾元件功耗低,穩(wěn)定性高,一致性好,廣泛應用于電池供電設備,全極霍爾元件不分南極北極,便于安裝。東莞HX6571霍爾開關</p><p

6.由于機械應力會造成霍爾器件磁敏感度的漂移，在使用安裝中應盡量減少施加到器件外殼和引線上的機械力，如管腳需要彎曲，請在距引線根部3mm以外操作。；7.將導線平行焊接在霍爾器件的引腳上，焊接時不能掰動霍爾器件引腳。；8.建議焊接溫度：電烙鐵焊接，建議溫度在350℃，**長5秒；波峰焊：建議比較高溫度260℃，**長3秒；紅外回流焊：建議比較高245℃，**長10秒。；9.焊點不得有毛刺，以避免將熱縮管刺破而導致短路燒壞霍爾器件。；10.熱縮管必須套在霍爾器件的引腳根部，保證器件充分絕緣，比較好在熱縮管及引線的下面再鋪一層絕緣紙。江蘇HX163霍爾開關</p><p>
