驅動器結構組成及作用(yong)

步(bu)進(jin)(jin)驅(qu)動(dong)(dong)器(qi)接(jie)收上位(wei)機(ji)(ji)的脈(mo)沖信(xin)(xin)號，配(pei)套驅(qu)動(dong)(dong)器(qi)價格，再(zai)分配(pei)脈(mo)沖信(xin)(xin)號，配(pei)套驅(qu)動(dong)(dong)器(qi)公(gong)司，再(zai)把信(xin)(xin)號功率(lv)放(fang)大(da)，再(zai)輸出給步(bu)進(jin)(jin)電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)繞組，使電(dian)(dian)(dian)動(dong)(dong)機(ji)(ji)轉動(dong)(dong)。由(you)此可知，步(bu)進(jin)(jin)驅(qu)動(dong)(dong)器(qi)一般由(you)脈(mo)沖信(xin)(xin)號發生電(dian)(dian)(dian)路、脈(mo)沖分配(pei)電(dian)(dian)(dian)路和功率(lv)放(fang)大(da)電(dian)(dian)(dian)路構成。

1、脈沖(chong)(chong)發生器(qi)（變頻(pin)(pin)信號(hao)源）：將產生的(de)基準頻(pin)(pin)率信號(hao)輸(shu)入給(gei)脈沖(chong)(chong)分配器(qi)，由(you)上位機或多諧振蕩器(qi)和單結晶體(ti)管構成的(de)弛張(zhang)振蕩器(qi)電路(lu)來發送(song)脈沖(chong)(chong)。

2、脈沖分配(pei)器（環形分配(pei)器）：由(you)雙(shuang)穩態觸發(fa)器和(he)門電路組成，也(ye)可(ke)由(you)可(ke)編程邏(luo)輯器件(jian)組成，是一(yi)(yi)個數字邏(luo)輯單(dan)元，作用是根據運行(xing)指令按一(yi)(yi)定的邏(luo)輯關系分配(pei)脈沖信號到每一(yi)(yi)相的脈沖放大器上。

驅動器的優點介紹

出色的(de)(de)(de)平均和低(di)速(su)(su)(su)(su)(su)范圍：步(bu)(bu)(bu)進(jin)驅(qu)(qu)動器(qi)體(ti)積小，吉林(lin)配(pei)套(tao)驅(qu)(qu)動器(qi)，在(zai)這樣一(yi)個小的(de)(de)(de)系(xi)(xi)統(tong)(tong)(tong)中(zhong)(zhong)，較好(hao)的(de)(de)(de)平均值和低(di)速(su)(su)(su)(su)(su)縮放是必(bi)要的(de)(de)(de)，小系(xi)(xi)統(tong)(tong)(tong)中(zhong)(zhong)的(de)(de)(de)較大(da)轉(zhuan)矩(ju)是步(bu)(bu)(bu)進(jin)驅(qu)(qu)動器(qi)的(de)(de)(de)一(yi)個流行特性，這也是步(bu)(bu)(bu)進(jin)驅(qu)(qu)動器(qi)和伺(si)服(fu)電(dian)機(ji)(ji)(ji)的(de)(de)(de)區(qu)別點。伺(si)服(fu)電(dian)機(ji)(ji)(ji)是在(zai)中(zhong)(zhong)高(gao)速(su)(su)(su)(su)(su)運行時(shi)能夠產生(sheng)平滑轉(zhuan)矩(ju)的(de)(de)(de)電(dian)機(ji)(ji)(ji)，配(pei)套(tao)驅(qu)(qu)動器(qi)公司，而(er)步(bu)(bu)(bu)進(jin)電(dian)機(ji)(ji)(ji)驅(qu)(qu)動器(qi)在(zai)中(zhong)(zhong)低(di)速(su)(su)(su)(su)(su)運行時(shi)會產生(sheng)高(gao)頻轉(zhuan)矩(ju)，隨著(zhu)轉(zhuan)速(su)(su)(su)(su)(su)范圍的(de)(de)(de)增大(da)，高(gao)頻轉(zhuan)矩(ju)逐漸減小。步(bu)(bu)(bu)進(jin)驅(qu)(qu)動器(qi)也可用于(yu)高(gao)速(su)(su)(su)(su)(su)操作(zuo)(zuo)，但周期(qi)有限。通常情況下，由于(yu)功率(lv)損耗大(da)、系(xi)(xi)統(tong)(tong)(tong)控制率(lv)低(di)、電(dian)機(ji)(ji)(ji)停止不準確度增加等(deng)原因(yin)，避免了(le)高(gao)速(su)(su)(su)(su)(su)測距操作(zuo)(zuo)。通常中(zhong)(zhong)速(su)(su)(su)(su)(su)操作(zuo)(zuo)中(zhong)(zhong)，伺(si)服(fu)和步(bu)(bu)(bu)進(jin)驅(qu)(qu)動器(qi)都(dou)配(pei)備良好(hao)。伺(si)服(fu)電(dian)機(ji)(ji)(ji)在(zai)低(di)速(su)(su)(su)(su)(su)時(shi)會出現(xian)問題，因(yin)為它們不利于(yu)上(shang)述操作(zuo)(zuo)，在(zai)實際應用中(zhong)(zhong)，步(bu)(bu)(bu)進(jin)驅(qu)(qu)動器(qi)更有用。由于(yu)其結(jie)構簡單，價格(ge)低(di)廉，因(yin)此將(jiang)其納入(ru)系(xi)(xi)統(tong)(tong)(tong)中(zhong)(zhong)也可以(yi)降低(di)生(sheng)產成(cheng)本。
