style="text-indent:25px">三相異步電動(dòng)機(jī)要旋轉(zhuǎn)起來的先決條件是具有一個(gè)旋轉(zhuǎn)磁場(chǎng)，三相異步電動(dòng)機(jī)的定子繞組就是用來產(chǎn)生旋轉(zhuǎn)磁場(chǎng)的。但相電源相與相之間的電壓在相位上是相差120度的，三相異步電動(dòng)機(jī)定子中的三個(gè)繞組在空間方位上也互差120度，這樣，當(dāng)在定子繞組中通入三相電源時(shí)，定子繞組就會(huì)產(chǎn)生一個(gè)旋轉(zhuǎn)磁場(chǎng)。電流每改變一個(gè)周期，旋轉(zhuǎn)磁場(chǎng)在空間旋轉(zhuǎn)一周，即旋轉(zhuǎn)磁場(chǎng)的旋轉(zhuǎn)速度與電流的改變是同步的。旋轉(zhuǎn)磁場(chǎng)的轉(zhuǎn)速為：n=60f/P式中f為電源頻率、P是磁場(chǎng)的磁極對(duì)數(shù)、n的單位是：每分鐘轉(zhuǎn)數(shù)。根據(jù)此式咱們知道，電動(dòng)機(jī)的轉(zhuǎn)速與磁極數(shù)和運(yùn)用電源的頻率有關(guān)。</p><p style="text-indent:25px">電源部可以直接以直流電輸入或以交流電輸入，如果輸入是交流電就得先經(jīng)轉(zhuǎn)換器轉(zhuǎn)成直流。不論是直流電輸入或交流電輸入要轉(zhuǎn)入電機(jī)線圈前須先將直流電壓由換流器（Inverter）轉(zhuǎn)成3相電壓來驅(qū)動(dòng)電機(jī)。換流器一般由6個(gè)功率晶體管分為上臂/下臂連接電機(jī)作為控制流經(jīng)電機(jī)線圈的開關(guān)。控制部則提供（脈沖寬度調(diào)制）決定功率晶體管開關(guān)頻度及換流器換相的時(shí)機(jī)。直流無刷電機(jī)一般希望使用在當(dāng)負(fù)載變動(dòng)時(shí)速度可以穩(wěn)定于設(shè)定值而不會(huì)變動(dòng)太大的速度控制，所以電機(jī)內(nèi)部裝有能感應(yīng)磁場(chǎng)的霍爾傳感器，作為速度之閉回路控制，同時(shí)也做為相序控制的依據(jù)。但這只是用來做為速度控制并不能拿來做為定位控制。直線電機(jī)具有起動(dòng)推力大、傳動(dòng)剛度高、動(dòng)態(tài)響應(yīng)快、定位精度高、行程長(zhǎng)度不受限制等優(yōu)點(diǎn)。</p><div
