【減速電機】步進電機加速控制方法

什么是(shi)(shi)(shi)(shi)步(bu)(bu)(bu)進(jin)電(dian)(dian)(dian)(dian)機？步(bu)(bu)(bu)進(jin)電(dian)(dian)(dian)(dian)機也稱為(wei)步(bu)(bu)(bu)進(jin)器或感應電(dian)(dian)(dian)(dian)機，是(shi)(shi)(shi)(shi)采用(yong)(yong)(yong)數(shu)(shu)字控(kong)制(zhi)傳動(dong)的(de)，屬于永磁結(jie)構電(dian)(dian)(dian)(dian)機，工(gong)作原(yuan)(yuan)理是(shi)(shi)(shi)(shi)電(dian)(dian)(dian)(dian)磁原(yuan)(yuan)理轉化(hua)成機械轉動(dong)；按(an)照(zhao)結(jie)構分類(lei)分為(wei)可變磁阻型(xing)、和混合(he)型(xing)，兩種電(dian)(dian)(dian)(dian)機的(de)用(yong)(yong)(yong)途大(da)不相(xiang)同，在使(shi)用(yong)(yong)(yong)過(guo)程中(zhong)我(wo)們經常(chang)會(hui)遇到在過(guo)于短的(de)時間里，控(kong)制(zhi)系統發出的(de)脈沖數(shu)(shu)太多(duo)，也就是(shi)(shi)(shi)(shi)脈沖頻率(lv)(lv)過(guo)，將導致(zhi)步(bu)(bu)(bu)進(jin)電(dian)(dian)(dian)(dian)機堵轉。要解決這個(ge)問題，必須采用(yong)(yong)(yong)加減速的(de)辦法。實現原(yuan)(yuan)理是(shi)(shi)(shi)(shi)在步(bu)(bu)(bu)進(jin)電(dian)(dian)(dian)(dian)機起步(bu)(bu)(bu)時，要給(gei)逐漸升的(de)脈沖頻率(lv)(lv)，減速時的(de)脈沖頻率(lv)(lv)需(xu)要逐漸減低(di)。這就是(shi)(shi)(shi)(shi)我(wo)們常(chang)說的(de)“加減速”方(fang)法。
