細(xì)分步即是將原來的一個整步步距分成多步驅(qū)動細(xì)分步后，各相的驅(qū)動電流再也不是非通即斷的開關(guān)狀態(tài)，而是一系列分級變化的電流臺階，細(xì)分步數(shù)越多、臺階越多，在步進(jìn)角之間的定位點(diǎn)就越多。對于二相步進(jìn)驅(qū)動器，若細(xì)分級數(shù)無窮大，則A、B相電流即為正弦、余弦波形。隨著細(xì)分級數(shù)的增加，電機(jī)運(yùn)行時跳躍角度減小。因?yàn)槭遣捎每臻g矢量算法求得的電流向量,所以是可以精確定位的,并細(xì)分步距角也上相當(dāng)精確的,本系列驅(qū)動器是用16位的專用運(yùn)算芯片采用付里葉級數(shù)的算法，通過D/A轉(zhuǎn)換逐步計算，得到各相所需電流值的,因?yàn)檗D(zhuǎn)距正比于電流通量又正比于激磁電流.所以通過控制A.B相的電流大小及方向,我們即可控制轉(zhuǎn)子到達(dá)各定位點(diǎn)的角度,并鎖定.
本系列驅(qū)動器的特點(diǎn)在于細(xì)分步工作方式,驅(qū)動器的細(xì)分即是對基步距角的細(xì)分,例如:二相步進(jìn)電機(jī)基步距角為1.8° .若 對其十細(xì)分,則細(xì)分步距角為0.18° . 本系列步進(jìn)電機(jī)驅(qū)動器因采用可選擇細(xì)分步驅(qū)動方式,所以可達(dá)高分辨率,最高分辨率可達(dá)360° /200*500=0.0036° (二相).360° /500*500=0.00144° (五相).所以非常 適用于高分辨率的場合及有平穩(wěn)運(yùn)行要求的場合.
