    [2]步進(jìn)電機(jī)主要構(gòu)造編輯三相磁阻式步進(jìn)電動(dòng)機(jī)模型的結(jié)構(gòu)示意圖如圖所示。它的定、轉(zhuǎn)子鐵心都由硅鋼片疊成。定子上有六個(gè)磁極，每兩個(gè)相對(duì)的磁極繞有同一相繞組，三相繞組接成星形作為控制繞組；轉(zhuǎn)子鐵心上沒有繞組，只有四個(gè)齒，齒寬等于定子極靴寬。[1]步進(jìn)電機(jī)步進(jìn)電機(jī)加減速過程控制技術(shù)正因?yàn)椴竭M(jìn)電機(jī)的廣應(yīng)用,對(duì)步進(jìn)電機(jī)的控制的研究也越來越多，在啟動(dòng)或加速時(shí)如果步進(jìn)脈沖變化太快，轉(zhuǎn)子由于慣性而跟隨不上電信號(hào)的變化，產(chǎn)生堵轉(zhuǎn)或失步在停止或減速時(shí)由于同樣原因則可能產(chǎn)生超步。為防止堵轉(zhuǎn)、失步和超步，提高工作頻率,要對(duì)步進(jìn)電機(jī)進(jìn)行升降速控制。[2]步進(jìn)電機(jī)的轉(zhuǎn)速取決于脈沖頻率、轉(zhuǎn)子齒數(shù)和拍數(shù)。其角速度與脈沖頻率成正比，而且在時(shí)間上與脈沖同步。因而在轉(zhuǎn)子齒數(shù)和運(yùn)行拍數(shù)一定的情況下，只要控制脈沖頻率即可獲得所需速度。由于步進(jìn)電機(jī)是借助它的同步力矩而啟動(dòng)的，為了不發(fā)生失步,啟動(dòng)頻率是不高的。特別是隨著功率的增加,轉(zhuǎn)子直徑增大，慣量增大，啟動(dòng)頻率和**高運(yùn)行頻率可能相差十倍之多。[2]步進(jìn)電機(jī)的起動(dòng)頻率特性使步進(jìn)電機(jī)啟動(dòng)時(shí)不能直接達(dá)到運(yùn)行頻率，而要有一個(gè)啟動(dòng)過程，即從一個(gè)低的轉(zhuǎn)速逐漸升速到運(yùn)行轉(zhuǎn)速。停止時(shí)運(yùn)行頻率不能立即降為零。60MM系列兩相步進(jìn)馬達(dá): TD60A15-40A，TD60A30-50A，TD60A315-50A。寧波leesn立三機(jī)電步進(jìn)馬達(dá)DMA860

    在控制步進(jìn)電機(jī)工作時(shí)，接口部件必須要有下列功能。①電壓隔離功能。單片機(jī)工作在5V，而步進(jìn)電機(jī)是工作在幾十V，甚至更高。一旦步進(jìn)電機(jī)的電壓串到單片機(jī)中，就會(huì)損壞單片機(jī);步進(jìn)電機(jī)的信號(hào)會(huì)干擾單片機(jī)，也可能導(dǎo)致系統(tǒng)工作失誤，因此接口器件必須有隔離功能。②信息傳遞功能。接口部件應(yīng)能夠把單片機(jī)的控制信息傳遞給步進(jìn)電機(jī)回路，產(chǎn)生工作所需的控制信息，對(duì)應(yīng)于不同的工作方式，接口部件應(yīng)能產(chǎn)生相應(yīng)的工作控制波形。③產(chǎn)生所需的不同頻率。為了使步進(jìn)電機(jī)以不同的速度工作，以適應(yīng)不同的目的，接口部件應(yīng)能產(chǎn)生不同的工作頻率。(2)電壓隔離接口。電壓隔離接口**于隔離低壓部分的單片機(jī)和高壓部分的步進(jìn)電機(jī)驅(qū)動(dòng)電路，以保證它們的正常工作。電壓隔離接口可以用脈沖變壓器或光電隔離器，基本上是采用光電隔離器。單片機(jī)輸出信號(hào)可以通過TTL門電路或者直接送到晶體管的基極，再由晶體管驅(qū)動(dòng)光電耦合器件的發(fā)光二極管。發(fā)光二極管的光照到光電耦合器件內(nèi)部的光敏管上，轉(zhuǎn)換成電信號(hào)，再去驅(qū)動(dòng)步進(jìn)電機(jī)的功率放大電路，電流放大接口是步進(jìn)電機(jī)功放電路的前置放大電路。它的作用是把光電隔離器的輸出信號(hào)進(jìn)行電流放大，以便向功放電路提供足夠大的驅(qū)動(dòng)電流。。步距角1.8°/步，雙極性；高轉(zhuǎn)速，溫升更低, 進(jìn)口配件，壽命更長；無錫LS步進(jìn)馬達(dá)DM845
