驅動器之間的(de)不同介紹(shao)

一，總線型步(bu)進驅動器，控制精度不同

兩(liang)相(xiang)(xiang)混合式(shi)步(bu)(bu)進電(dian)(dian)機(ji)(ji)的(de)步(bu)(bu)距(ju)(ju)角(jiao)(jiao)一(yi)般為(wei)3.6度(du)(du)和1.8度(du)(du)，五相(xiang)(xiang)混合式(shi)步(bu)(bu)進電(dian)(dian)機(ji)(ji)的(de)步(bu)(bu)距(ju)(ju)角(jiao)(jiao)一(yi)般為(wei)0.72度(du)(du)和0.36度(du)(du)。還(huan)有(you)一(yi)些高的(de)性能的(de)步(bu)(bu)進電(dian)(dian)機(ji)(ji)，步(bu)(bu)距(ju)(ju)角(jiao)(jiao)更小。如四(si)通(tong)公司(si)生(sheng)產的(de)線切(qie)割(ge)機(ji)(ji)床用步(bu)(bu)進電(dian)(dian)機(ji)(ji)，步(bu)(bu)距(ju)(ju)角(jiao)(jiao)為(wei)0.09度(du)(du)；bergerlahr生(sheng)產的(de)三相(xiang)(xiang)混合式(shi)步(bu)(bu)進電(dian)(dian)機(ji)(ji)的(de)步(bu)(bu)距(ju)(ju)角(jiao)(jiao)可以通(tong)過dip開關設置為(wei)1.8、0.9、0.72、0.36、0.18、0.09、0.072、0.036，兼容(rong)兩(liang)相(xiang)(xiang)和五相(xiang)(xiang)混合式(shi)步(bu)(bu)進電(dian)(dian)機(ji)(ji)的(de)步(bu)(bu)距(ju)(ju)角(jiao)(jiao)。

二，低頻特性不同

步(bu)(bu)進(jin)電(dian)(dian)機在(zai)(zai)低(di)速時(shi)容(rong)易(yi)產生低(di)頻(pin)振動(dong)(dong)(dong)。振動(dong)(dong)(dong)頻(pin)率(lv)(lv)與(yu)負載(zai)和驅動(dong)(dong)(dong)器性能有(you)關，一(yi)(yi)般認為振動(dong)(dong)(dong)頻(pin)率(lv)(lv)為電(dian)(dian)機空載(zai)起飛頻(pin)率(lv)(lv)的一(yi)(yi)半。這種低(di)頻(pin)振動(dong)(dong)(dong)的現(xian)象，是由(you)步(bu)(bu)進(jin)電(dian)(dian)機的工作(zuo)原理決定(ding)的，對機器的正(zheng)常(chang)運(yun)行非(fei)常(chang)不利。步(bu)(bu)進(jin)電(dian)(dian)機低(di)速工作(zuo)時(shi)，一(yi)(yi)般應采用(yong)(yong)阻(zu)尼(ni)技術(shu)來(lai)克服低(di)頻(pin)振動(dong)(dong)(dong)現(xian)象，總(zong)線型步(bu)(bu)進(jin)驅動(dong)(dong)(dong)器公司，如在(zai)(zai)電(dian)(dian)機上加阻(zu)尼(ni)器或在(zai)(zai)驅動(dong)(dong)(dong)器上采用(yong)(yong)細分(fen)技術(shu)。

Ac servo motor運行非常流(liu)暢，即使低速也不會有震動。交流(liu)伺服系統具有共振(zhen)(zhen)抑制功能，可以彌補(bu)機械剛性的不足，系統具有頻率分析(fft)功能，可以檢測機器(qi)的共振(zhen)(zhen)點(dian)，方便系統調整。

驅動器調速方法介紹

隨著電(dian)力電(dian)子(zi)技(ji)術的(de)(de)飛速(su)(su)(su)發展，變頻調(diao)(diao)速(su)(su)(su)的(de)(de)性(xing)能指標可以完(wan)全達到甚至超(chao)過(guo)直流(liu)電(dian)動機(ji)調(diao)(diao)速(su)(su)(su)系(xi)統 。步(bu)進電(dian)動機(ji)驅(qu)動器(qi)(qi)通過(guo)調(diao)(diao)節(jie)輸入驅(qu)動器(qi)(qi)的(de)(de)脈(mo)沖頻率和驅(qu)動器(qi)(qi)的(de)(de)細分參數來調(diao)(diao)節(jie)步(bu)進電(dian)動機(ji)的(de)(de)速(su)(su)(su)度 。實際上，它(ta)是控制(zhi)單位時(shi)間內步(bu)進電(dian)機(ji)的(de)(de)步(bu)數 。步(bu)進電(dian)機(ji)驅(qu)動器(qi)(qi)的(de)(de)調(diao)(diao)速(su)(su)(su)方(fang)法主(zhu)要(yao)包(bao)括六個：改變極對數調(diao)(diao)速(su)(su)(su)、變頻調(diao)(diao)速(su)(su)(su)、換(huan)向器(qi)(qi)電(dian)機(ji)調(diao)(diao)速(su)(su)(su)、串級調(diao)(diao)速(su)(su)(su)、定子(zi)調(diao)(diao)壓調(diao)(diao)速(su)(su)(su)和電(dian)磁轉差離合器(qi)(qi)調(diao)(diao)速(su)(su)(su) 。
