驅動器

驅(qu)(qu)動器均采用數字(zi)信號(hao)處理器(DSP)作為控(kong)制(zhi)主要(yao)，可(ke)以實(shi)現比較復雜的控(kong)制(zhi)算(suan)法，實(shi)現數字(zi)化、網絡化和智(zhi)能(neng)(neng)化。功率器件普遍采用以智(zhi)能(neng)(neng)功率模塊(IPM)為主要(yao)設(she)計的驅(qu)(qu)動電路，配(pei)套驅(qu)(qu)動器公司，IPM內(nei)部集成(cheng)了驅(qu)(qu)動電路，同時具有過電壓(ya)、過電流(liu)、過熱、欠壓(ya)等故障檢測保護(hu)電路，在主回路中還(huan)加入(ru)了軟啟動電路，以減小啟動過程(cheng)對驅(qu)(qu)動器的沖擊。

什么是驅動器？

步(bu)(bu)(bu)進(jin)(jin)驅(qu)(qu)動(dong)(dong)器(qi)(qi)(qi)是(shi)驅(qu)(qu)動(dong)(dong)步(bu)(bu)(bu)進(jin)(jin)電(dian)(dian)(dian)機(ji)(ji)運行(xing)的(de)(de)(de)功率放大器(qi)(qi)(qi)，它能接收控(kong)(kong)制(zhi)(zhi)器(qi)(qi)(qi)（PLC/單(dan)片機(ji)(ji)等）發送來的(de)(de)(de)控(kong)(kong)制(zhi)(zhi)信(xin)號(hao)并控(kong)(kong)制(zhi)(zhi)步(bu)(bu)(bu)進(jin)(jin)電(dian)(dian)(dian)機(ji)(ji)轉(zhuan)過(guo)相(xiang)應的(de)(de)(de)角度(du)/步(bu)(bu)(bu)數。常(chang)見的(de)(de)(de)控(kong)(kong)制(zhi)(zhi)信(xin)號(hao)是(shi)脈沖(chong)(chong)(chong)信(xin)號(hao)，步(bu)(bu)(bu)進(jin)(jin)驅(qu)(qu)動(dong)(dong)器(qi)(qi)(qi)接收到一(yi)個有(you)(you)(you)效脈沖(chong)(chong)(chong)就控(kong)(kong)制(zhi)(zhi)步(bu)(bu)(bu)進(jin)(jin)電(dian)(dian)(dian)機(ji)(ji)運行(xing)一(yi)步(bu)(bu)(bu)。具有(you)(you)(you)細(xi)分功能的(de)(de)(de)步(bu)(bu)(bu)進(jin)(jin)驅(qu)(qu)動(dong)(dong)器(qi)(qi)(qi)可以改變步(bu)(bu)(bu)進(jin)(jin)電(dian)(dian)(dian)機(ji)(ji)的(de)(de)(de)固有(you)(you)(you)步(bu)(bu)(bu)距角，達到更大的(de)(de)(de)控(kong)(kong)制(zhi)(zhi)精度(du)、降(jiang)低(di)振動(dong)(dong)及提高輸出轉(zhuan)矩；除(chu)了脈沖(chong)(chong)(chong)信(xin)號(hao)，具有(you)(you)(you)總線通信(xin)功能的(de)(de)(de)步(bu)(bu)(bu)進(jin)(jin)驅(qu)(qu)動(dong)(dong)器(qi)(qi)(qi)還能接收總線信(xin)號(hao)控(kong)(kong)制(zhi)(zhi)步(bu)(bu)(bu)進(jin)(jin)電(dian)(dian)(dian)機(ji)(ji)進(jin)(jin)行(xing)相(xiang)應的(de)(de)(de)動(dong)(dong)作。

驅(qu)動器常見故障及解(jie)決辦法

步進電機一(yi)直震動(dong)是什么原因，可(ke)能是信號電壓低(di)所導致(zhi)的，需要去利(li)用電機的的震點去錯(cuo)開這個震動(dong)頻率然(ran)后去容(rong)易交換同一(yi)相。

步(bu)進電(dian)機(ji)堵住轉，可能是因(yin)為(wei)電(dian)機(ji)的(de)扭(niu)矩(ju)力太(tai)小了(le)(le)，需要(yao)去(qu)選擇大扭(niu)矩(ju)的(de)電(dian)機(ji)。如果(guo)(guo)排(pai)除了(le)(le)這個問(wen)題，山東(dong)配套驅動器(qi)，那(nei)么就(jiu)(jiu)是加(jia)速(su)的(de)時間(jian)過于(yu)太(tai)短了(le)(le)，只(zhi)需要(yao)加(jia)大加(jia)速(su)的(de)時間(jian)；如果(guo)(guo)是電(dian)壓(ya)過低(di)了(le)(le)就(jiu)(jiu)是電(dian)流需要(yao)去(qu)加(jia)高(gao)一點，提高(gao)電(dian)流與(yu)電(dian)壓(ya)，在一個合適的(de)范圍之內。

這些(xie)大(da)概(gai)就是步(bu)進(jin)電機驅動的(de)的(de)一(yi)些(xie)常見問(wen)(wen)題(ti)和解決方法，根(gen)(gen)據具體問(wen)(wen)題(ti)具體分析，只要根(gen)(gen)據上面(mian)的(de)問(wen)(wen)題(ti)去一(yi)步(bu)步(bu)進(jin)行排(pai)除，那么這些(xie)問(wen)(wen)題(ti)一(yi)定(ding)能夠迎刃而解。
