步進(jìn)電機(jī)驅(qū)動(dòng)器有三種基本的步進(jìn)電機(jī)驅(qū)動(dòng)模式:整步、半步、細(xì)分。其主要區(qū)別在于電機(jī)線圈電流的控制精度(即激磁方式)。
整步驅(qū)動(dòng)
在整步運(yùn)行中,同一種步進(jìn)電機(jī)既可配整/半步驅(qū)動(dòng)器也可配細(xì)分驅(qū)動(dòng)器,但運(yùn)行效果不同。步進(jìn)電機(jī)驅(qū)動(dòng)器按脈沖/方向指令對兩相步進(jìn)電機(jī)的兩個(gè)線圈循環(huán)激磁(即將線圈充電設(shè)定電流),這種驅(qū)動(dòng)方式的每個(gè)脈沖將使電機(jī)移動(dòng)一個(gè)基本步距角,即1.80度 (標(biāo)準(zhǔn)兩相電機(jī)的一圈共有200個(gè)步距角)。
半步驅(qū)動(dòng)
在單相激磁時(shí),電機(jī)轉(zhuǎn)軸停至整步位置上,驅(qū)動(dòng)器收到下一脈沖后,如給另一相激磁且保持原來相繼處在激磁狀態(tài),則電機(jī)轉(zhuǎn)軸將移動(dòng)半個(gè)步距角,停在相鄰兩個(gè)整步位置的中間。如此循環(huán)地對兩相線圈進(jìn)行單相然后雙相激磁步進(jìn)電機(jī)將以每個(gè)脈沖0.90度的半步方式轉(zhuǎn)動(dòng)。山社電機(jī)供應(yīng)的所有的整/半步驅(qū)動(dòng)器都可以執(zhí)行整步和半步驅(qū)動(dòng),由驅(qū)動(dòng)器撥碼開關(guān)的撥位進(jìn)行選擇。和整步方式相比,半步方式具有精度高一倍和低速運(yùn)行時(shí)振動(dòng)較小的優(yōu)點(diǎn),所以實(shí)際使用整/半步驅(qū)動(dòng)器時(shí)一般選用半步模式。
細(xì)分驅(qū)動(dòng)
細(xì)分驅(qū)動(dòng)模式具有低速振動(dòng)極小和定位精度高兩大優(yōu)點(diǎn)。對于有時(shí)需要低速運(yùn)行(即電機(jī)轉(zhuǎn)軸有時(shí)工作在60rpm以下)或定位精度要求小于0.90度的步進(jìn)應(yīng)用中,細(xì)分型步進(jìn)電機(jī)驅(qū)動(dòng)器獲得廣泛應(yīng)用。其基本原理是對電機(jī)的兩個(gè)線圈分別按正弦和余弦形的臺階進(jìn)行精密電流控制,從而使得一個(gè)步距角的距離分成若干個(gè)細(xì)分步完成。例如十六細(xì)分的驅(qū)動(dòng)方式可使每圈200標(biāo)準(zhǔn)步的步進(jìn)電機(jī)達(dá)到每圈200*16=3200步的運(yùn)行精度(即0.1125°)。
