驅動器的驅動方式

單電壓功率驅動

實(shi)用單電(dian)壓(ya)功率(lv)驅動(dong)接口及單步響應曲線電(dian)路(lu)如圖5所示。在電(dian)機繞組回(hui)路(lu)中串(chuan)有(you)電(dian)阻Rs，使電(dian)機回(hui)路(lu) 雙電(dian)壓(ya)功率(lv)驅動(dong)接口時間常數(shu)減小，高頻(pin)時電(dian)機能(neng)產生較大的電(dian)磁(ci)轉矩，還能(neng)緩(huan)解電(dian)機的低頻(pin)共振現象，但它引起附(fu)加的損耗。一般情況下(xia)，簡(jian)單單電(dian)壓(ya)驅動(dong)線路(lu)中，Rs是(shi)不可缺少的。Rs步進電(dian)機單步響應的改善。

控制器(qi)與步驅(qu)動器(qi)區別

常規步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)控(kong)(kong)制(zhi)(zhi)系統為(wei)步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)、步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)驅(qu)動(dong)器(qi)(qi)、以及步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)，步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)是在(zai)步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)驅(qu)動(dong)器(qi)(qi)之上(shang)的(de)部分(fen)，它可以給步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)驅(qu)動(dong)器(qi)(qi)發出高速脈沖信(xin)(xin)號，步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)驅(qu)動(dong)器(qi)(qi)接受由(you)步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)發來的(de)高速脈沖信(xin)(xin)號，甘肅(su)步(bu)進(jin)(jin)(jin)(jin)(jin)驅(qu)動(dong)器(qi)(qi)，并將(jiang)該信(xin)(xin)號放(fang)大，用以驅(qu)動(dong)步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)，由(you)此步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)控(kong)(kong)制(zhi)(zhi)器(qi)(qi)與步(bu)進(jin)(jin)(jin)(jin)(jin)電(dian)機(ji)(ji)(ji)驅(qu)動(dong)器(qi)(qi)區別有以下(xia)幾點

1、步進(jin)電機控(kong)制器是脈沖發(fa)生(sheng)器，步進(jin)驅動器價(jia)格(ge)，可產生(sheng)高速脈沖

2、步(bu)進電機控制器相(xiang)對步(bu)進電機驅(qu)動(dong)器更多樣化，步(bu)進電機驅(qu)動(dong)器一(yi)(yi)般功能(neng)單一(yi)(yi)，步(bu)進驅(qu)動(dong)器公(gong)司(si)，主(zhu)要是(shi)放大脈(mo)沖信號功能(neng)

3、步進(jin)電機控(kong)制器(qi)一般可編程(cheng)，步進(jin)電機驅(qu)動器(qi)直(zhi)接(jie)接(jie)收脈沖(chong)信(xin)號

4、步進電(dian)機控制(zhi)器(qi)為低壓控制(zhi)信號，步進電(dian)機驅動器(qi)有高低壓多種

驅動器怎么設置細分

設(she)置(zhi)步進(jin)(jin)驅動器的細(xi)(xi)分(fen)(fen)數，通常細(xi)(xi)分(fen)(fen)數越(yue)高(gao)，步進(jin)(jin)驅動器價(jia)格，控制分(fen)(fen)辨率越(yue)高(gao)。但細(xi)(xi)分(fen)(fen)數太高(gao)則(ze)影響(xiang)到(dao)進(jin)(jin)給(gei)(gei)(gei)速(su)(su)度。一般來說，對(dui)于模具機(ji)用戶(hu)可考慮(lv)脈沖(chong)(chong)當量(liang)為(wei)(wei)0.001mm/P（此(ci)時進(jin)(jin)給(gei)(gei)(gei)速(su)(su)度為(wei)(wei)9600mm/min）或(huo)者0.0005mm/P（此(ci)時進(jin)(jin)給(gei)(gei)(gei)速(su)(su)度為(wei)(wei)4800mm/min）；對(dui)于精度要(yao)求(qiu)不(bu)高(gao)的用戶(hu)，脈沖(chong)(chong)當量(liang)可設(she)置(zhi)的大一些，如0.002mm/P（此(ci)時進(jin)(jin)給(gei)(gei)(gei)速(su)(su)度為(wei)(wei)19200mm/min）或(huo)0.005mm/P（此(ci)時進(jin)(jin)給(gei)(gei)(gei)速(su)(su)度為(wei)(wei)48000mm/min）。對(dui)于兩相步進(jin)(jin)電機(ji)，脈沖(chong)(chong)當量(liang)計算方法(fa)如下(xia)：脈沖(chong)(chong)當量(liang)=絲杠螺(luo)距÷細(xi)(xi)分(fen)(fen)數÷200。
