磁旋轉(zhuǎn)編碼器主要由磁阻傳感器、充磁磁鼓、信號(hào)處理電路和機(jī)械結(jié)構(gòu)部分組成。它采用磁阻變化原理檢測(cè)微弱磁場(chǎng)信號(hào)的變化。磁鼓刻錄成等間距的小磁極，磁極被磁化后，磁鼓在旋轉(zhuǎn)時(shí)能在周圍空間分布周期性變化的磁場(chǎng)。在一定的間距上，這個(gè)磁場(chǎng)的Ｙ方向分量在每個(gè)磁極的正上方位置，磁旋轉(zhuǎn)編碼器的值為零；在相鄰磁極的正中位置，它的值為zui大。

磁鼓旋轉(zhuǎn)時(shí)磁阻元件由于具有磁阻效應(yīng)，磁旋轉(zhuǎn)編碼器的阻值會(huì)隨著磁場(chǎng)的改變而改變，在外加電勢(shì)的作用下，變化的電阻值導(dǎo)致電阻上的電壓變化，橋式電路的輸出端的電壓也就隨之發(fā)生變化。因此，橋式電路的輸出信號(hào)和磁鼓的旋轉(zhuǎn)是緊密相聯(lián)的。磁鼓每旋轉(zhuǎn)一個(gè)磁化長(zhǎng)度，磁場(chǎng)變化半周，信號(hào)輸出則變化一個(gè)周期，磁鼓上磁極對(duì)的數(shù)量和輸出信號(hào)的周期數(shù)在旋轉(zhuǎn)一周時(shí)是相等的。所以通過(guò)測(cè)定輸出信號(hào)的周期數(shù)或周期時(shí)間就可知道磁鼓的位置和旋轉(zhuǎn)速度了。可查看磁性編碼器的更多介紹。
