步進(jìn)電機(jī)和普通電動機(jī)不同之處是步進(jìn)電機(jī)接受脈沖信號的控制。步進(jìn)電機(jī)靠一種叫環(huán)形分配器的電子開關(guān)器件，通過功率放大器使勵磁繞組按照順序輪流接通直流電源。由于勵磁繞組在空間中按的規(guī)律排列，輪流和直流電源接通后，就會在空間形成一種階躍變化的旋轉(zhuǎn)磁場，使轉(zhuǎn)子步進(jìn)式的轉(zhuǎn)動，隨著脈沖頻率的增高，轉(zhuǎn)速就會增大。步進(jìn)電機(jī)的旋轉(zhuǎn)同時與相數(shù)、分配數(shù)、轉(zhuǎn)子齒輪數(shù)有關(guān)。

現(xiàn)在比較常用的步進(jìn)電機(jī)包括反應(yīng)式步進(jìn)電機(jī)、永磁式步進(jìn)電機(jī)、混合式步進(jìn)電機(jī)和單相式步進(jìn)電機(jī)等。其中反應(yīng)式步進(jìn)電機(jī)的轉(zhuǎn)子磁路由軟磁材料制成，定子上有多相勵磁繞組，利用磁導(dǎo)的變化產(chǎn)生轉(zhuǎn)矩。現(xiàn)階段，反應(yīng)式步進(jìn)電機(jī)獲得多的應(yīng)用。

步進(jìn)電機(jī)和普通電機(jī)的區(qū)別主要就在于其脈沖驅(qū)動的形式，正是這個特點(diǎn)，步進(jìn)電機(jī)可以和現(xiàn)代的數(shù)字控制技術(shù)相結(jié)合。不過步進(jìn)電機(jī)在控制的精度、速度變化范圍、低速性能方面都不如傳統(tǒng)的閉環(huán)控制的直流伺服電動機(jī)。在精度不是需要特別高的場合就可以使用步進(jìn)電機(jī)，步進(jìn)電機(jī)可以發(fā)揮其結(jié)構(gòu)簡單、可靠性高和成本低的特點(diǎn)。使用恰當(dāng)?shù)臅r候，甚至可以和直流伺服電動機(jī)性能相媲美。
