【導(dǎo)讀】步進電機是一種將電脈沖轉(zhuǎn)化為角位移的數(shù)字控制執(zhí)行機構(gòu)。步進電機具有控制簡便、定位準(zhǔn)確等特點。任意設(shè)定步進電機的轉(zhuǎn)速、旋轉(zhuǎn)角度、轉(zhuǎn)動次數(shù)和控制步進電機的運行狀態(tài)。簡化控制電路,降低生產(chǎn)成本,提高系統(tǒng)的運行效率和靈活性。累計誤差，具有良好的跟隨性。步進電機的動態(tài)響應(yīng)快，易于起停、正反轉(zhuǎn)及變速。當(dāng)寬的范圍內(nèi)平滑調(diào)節(jié)，低速下仍能保證獲得大轉(zhuǎn)矩。步進電機只能通過脈沖。步進電機存在振蕩。步進電機是自動控制系統(tǒng)中常用的執(zhí)行部件。由于步進電機能夠直接接受數(shù)字信號,而不需數(shù)。目前打字機、計算機外部設(shè)備、數(shù)控機床、傳真機等設(shè)備中都使用了步進電機。步進電機是將電脈沖信號轉(zhuǎn)變?yōu)榻俏灰苹蚓€位移的開環(huán)控制元件。
