    ω為每秒角速度，單位為弧度，n為每分鐘轉(zhuǎn)速，M為力矩單位為牛頓·米P=2πfM/400(半步工作)其中f為每秒脈沖數(shù)(簡稱PPS)折疊編輯本段常用術(shù)語步距角:每輸入一個(gè)電脈沖信號(hào)時(shí)轉(zhuǎn)子轉(zhuǎn)過的角度稱為步距角。步距角的大小可以直接影響電機(jī)的運(yùn)行精度;保持轉(zhuǎn)矩:是指步進(jìn)電機(jī)通電但沒有轉(zhuǎn)動(dòng)時(shí)，定子鎖住轉(zhuǎn)子的力矩。它是步進(jìn)電機(jī)**重要的參數(shù)之一，通常步進(jìn)電機(jī)在低速時(shí)的力矩接近保持轉(zhuǎn)矩。由于步進(jìn)電機(jī)的輸出力矩隨速度的增大而不斷衰減，輸出功率也隨速度的增大而變化，所以保持轉(zhuǎn)矩就成為了衡量步進(jìn)電機(jī)**重要的參數(shù)之一。比如，當(dāng)人們說2Nm的步進(jìn)電機(jī)，在沒有特殊說明的情況下是指保持轉(zhuǎn)矩為2Nm的步進(jìn)電機(jī);定位轉(zhuǎn)矩:定位轉(zhuǎn)矩是指步進(jìn)電機(jī)沒有通電的情況下，定子鎖住轉(zhuǎn)子的力矩。反應(yīng)式步進(jìn)電機(jī)的轉(zhuǎn)子不是永磁材料，所以它沒有定轉(zhuǎn)矩;空載啟動(dòng)頻率:指步進(jìn)電機(jī)能夠不失步啟動(dòng)的**高脈沖頻率;啟動(dòng)矩頻特性:在給定的驅(qū)動(dòng)條件下，負(fù)載慣量一定時(shí)，啟動(dòng)頻率與負(fù)載轉(zhuǎn)矩之間的關(guān)系稱為啟動(dòng)矩頻特性，又稱牽入特性。運(yùn)行矩頻特性:在負(fù)載慣量不變時(shí)，運(yùn)行頻率與負(fù)載轉(zhuǎn)矩之間的關(guān)系稱為運(yùn)行矩頻特性，又稱牽出特性。39系列系列步進(jìn)電機(jī) STH-39D0009，STH-39D0019，STH-39D1143，STH-39D1144，STH-39D2008?。無錫立三leesn步進(jìn)馬達(dá)DMA545

    不因電源電壓、負(fù)載環(huán)境的波動(dòng)而變化的特性，這種升速方法的加速度是恒定的，其缺點(diǎn)是未充分考慮步進(jìn)電機(jī)輸出力矩隨速度變化的特性，步進(jìn)電機(jī)在高速時(shí)會(huì)發(fā)生失步。[2]步進(jìn)電機(jī)步進(jìn)電機(jī)的細(xì)分驅(qū)動(dòng)控制步進(jìn)電機(jī)由于受到自身制造工藝的限制，如步距角的大小由轉(zhuǎn)子齒數(shù)和運(yùn)行拍數(shù)決定，但轉(zhuǎn)子齒數(shù)和運(yùn)行拍數(shù)是有限的，因此步進(jìn)電機(jī)的步距角一般較大并且是固定的,步進(jìn)的分辨率低、缺乏靈活性、在低頻運(yùn)行時(shí)振動(dòng)，噪音比其他微電機(jī)都高,使物理裝置容易疲勞或損壞。這些缺點(diǎn)使步進(jìn)電機(jī)只能應(yīng)用在一些要求較低的場合，對(duì)要求較高的場合，只能采取閉環(huán)控制，增加了系統(tǒng)的復(fù)雜性，這些缺點(diǎn)嚴(yán)重限制了步進(jìn)電機(jī)作為優(yōu)良的開環(huán)控制組件的有效利用。細(xì)分驅(qū)動(dòng)技術(shù)在一定程度上有效地克服了這些缺點(diǎn)。[2]步進(jìn)電機(jī)細(xì)分驅(qū)動(dòng)技術(shù)是年代中期發(fā)展起來的一種可以明顯改善步進(jìn)電機(jī)綜合使用性能的驅(qū)動(dòng)技術(shù)。年美國學(xué)者、第1次在美國增量運(yùn)動(dòng)控制系統(tǒng)及器件年會(huì)上提出步進(jìn)電機(jī)步距角細(xì)分的控制方法。在其后的二十多年里,步進(jìn)電機(jī)細(xì)分驅(qū)動(dòng)得到了很大的發(fā)展。逐步發(fā)展到上世紀(jì)九十年代完全成熟的。我國對(duì)細(xì)分驅(qū)動(dòng)技術(shù)的研究,起步時(shí)間與國外相差無幾。[2]在九十年代中期的到了較大的發(fā)展。無錫立三leesn步進(jìn)馬達(dá)DMA545
