【正文】 to apply over a long period of time, to its technique also pare in order to acquaint with, especially typical of hybrid type39。t start, and the panion have a roar the interjection tread to have a technique parameter into the electrical engineering: empty carry start frequency, then tread into electrical engineering at empty carry under circumstance can start normally of pulse frequency, if the pulse frequency is high in should be worth., The electrical engineering can39。（2）、對(duì)電動(dòng)機(jī)進(jìn)行綜合設(shè)計(jì)即把轉(zhuǎn)速位置傳感器，減速齒輪等和電動(dòng)機(jī)本體綜合設(shè)計(jì)在一起，這樣使其能方便地組成一個(gè)閉環(huán)系統(tǒng)，因而具有一更加優(yōu)越的控制性能?？梢酝ㄟ^(guò)控制脈沖個(gè)數(shù)來(lái)控制角位移最，從而達(dá)到確定位的目的。（2）、步進(jìn)電機(jī)外表允許的最高溫度步進(jìn)電機(jī)溫度過(guò)高首先會(huì)使電機(jī)的磁性材料退磁，從而導(dǎo)致力矩下降乃至于失步，因此電機(jī)外表允許的最高溫度應(yīng)取決于小同電機(jī)磁性材料的退磁點(diǎn)。步進(jìn)電機(jī)的基本特點(diǎn):（1）、一般步進(jìn)電機(jī)的精度為步進(jìn)角的35%且不累積。當(dāng)步進(jìn)驅(qū)動(dòng)器接收到一個(gè)脈沖信號(hào)，它就驅(qū)動(dòng)步進(jìn)電機(jī)按設(shè)定的方向轉(zhuǎn)動(dòng)一個(gè)固定的角度稱為“步距角”，它的旋轉(zhuǎn)是以固定的角度一步一步運(yùn)行的。國(guó)內(nèi)外電機(jī)的發(fā)展趨勢(shì):（1）、繼續(xù)沿著小型化的方向發(fā)展隨著電動(dòng)機(jī)本身應(yīng)用領(lǐng)域的拓寬以及各類整機(jī)的不斷小型化，要求與之配套的電動(dòng)機(jī)也必須越來(lái)越小，在57, 42機(jī)座號(hào)的電動(dòng)機(jī)應(yīng)用了多年后，現(xiàn)在其機(jī)座號(hào)向3 9, 3 5,30, 25方向向下延伸。 The frequency is more high, anti to electromotive force more big ，big in its function, the electrical engineering enlarges with the frequency(or speed) but mutually the electric current let up, causing the dint descend thus.（4）、 can revolve normally when 4 enter electrical engineering low speed, but if high in certain the speed can39。s, has been is the type of to tread to share governance position into the electric motor, the mixture type tread into the electric motor is after 8039。t accumulate error margin accuracy to 100 to divide 100 of characteristics, be suffused with to apply in various open a wreath control PLC which enter electrical engineering technique.make the importation tread to be subjected to a homologous control into total amount and pulse frequency of the importation pulse of electrical engineering. Establish the pulse signal occurrence that a pulse total amount and pulse frequency can control a machine therefore and in control，software。這種現(xiàn)狀對(duì)步進(jìn)電動(dòng)機(jī)的發(fā)展是不利的。因此在控制軟件上設(shè)置一個(gè)脈沖總數(shù)和脈沖頻率可控的脈沖信號(hào)發(fā)生器。頻率越高，反向電動(dòng)勢(shì)越大在它的作用大，電機(jī)隨頻率(或速度)的增大而相電流減小，從而導(dǎo)致力矩下降。中文資料淺析步進(jìn)電機(jī)的PLC控制技術(shù)與發(fā)展趨勢(shì)概述：隨著微電子技術(shù)和計(jì)算機(jī)技術(shù)的發(fā)展，可編程序控制器有一了突飛猛進(jìn)的發(fā)展，其功能已遠(yuǎn)遠(yuǎn)超出了邏輯控制、順序控制的范圍，它與計(jì)算機(jī)有一效結(jié)合，可進(jìn)行模擬最控制，具有一遠(yuǎn)程通信功能等。（4）、步進(jìn)電機(jī)低速時(shí)可以正常運(yùn)轉(zhuǎn)，但若高于一定速度就無(wú)法啟動(dòng)，并伴有一嘯叫聲步進(jìn)電機(jī)有一個(gè)技術(shù)參數(shù):空載啟動(dòng)頻率，即步進(jìn)電機(jī)在空載情況下能夠正常啟動(dòng)的脈沖頻率，如果脈沖頻率高于該值.，電機(jī)不能正常啟動(dòng)，可能發(fā)生丟步或堵轉(zhuǎn)。對(duì)于頻率較低的控制脈沖，可以利用PL的定時(shí)器構(gòu)成，脈沖頻率可以通過(guò)定時(shí)器的定時(shí)常數(shù)控制脈沖周期，脈沖總數(shù)控制則可以設(shè)置一脈沖計(jì)數(shù)器C10當(dāng)脈沖數(shù)達(dá)到設(shè)定值時(shí)，計(jì)數(shù)器C1。英文資料The shallow treads into the PLC control technique and development trend
