絲桿步(bu)進電(dian)機的(de)用途詳解

1.絲桿步進電動機工作時每相繞組不是恒定地通電，而是按一(yi)定的規律輪流(liu)通電。

2.每輸入一個脈(mo)沖(chong)電(dian)信號轉(zhuan)子轉(zhuan)過的角(jiao)度稱(cheng)為步(bu)距角(jiao)。

3.絲(si)桿(gan)步(bu)進(jin)(jin)(jin)電機(ji)可(ke)(ke)(ke)以按特定指令進(jin)(jin)(jin)行(xing)角度(du)控(kong)(kong)制(zhi)，也可(ke)(ke)(ke)以進(jin)(jin)(jin)行(xing)速(su)度(du)控(kong)(kong)制(zhi)。角度(du)控(kong)(kong)制(zhi)時(shi)，每輸入一(yi)(yi)個脈(mo)(mo)沖(chong)，定子繞(rao)組就(jiu)(jiu)換(huan)接一(yi)(yi)次，微型(xing)(xing)步(bu)進(jin)(jin)(jin)電機(ji)價格，輸出(chu)軸(zhou)就(jiu)(jiu)轉(zhuan)過一(yi)(yi)個角度(du)，其步(bu)數與(yu)脈(mo)(mo)沖(chong)數一(yi)(yi)致，輸出(chu)軸(zhou)轉(zhuan)動(dong)的角位移量與(yu)輸入脈(mo)(mo)沖(chong)成正比(bi)(bi)。速(su)度(du)控(kong)(kong)制(zhi)時(shi)，微型(xing)(xing)步(bu)進(jin)(jin)(jin)電機(ji)價格，步(bu)進(jin)(jin)(jin)電機(ji)繞(rao)組中送入的是連(lian)續脈(mo)(mo)沖(chong)，各(ge)相繞(rao)組不斷(duan)地輪流通(tong)電，步(bu)進(jin)(jin)(jin)電機(ji)連(lian)續動(dong)轉(zhuan)，它的轉(zhuan)速(su)與(yu)脈(mo)(mo)沖(chong)頻率成正比(bi)(bi)。改變通(tong)電順序(xu)，即改變定子磁場旋轉(zhuan)方向，就(jiu)(jiu)可(ke)(ke)(ke)以控(kong)(kong)制(zhi)電機(ji)正轉(zhuan)或(huo)是反轉(zhuan)。

4.絲桿步進(jin)電機(ji)具有自(zi)鎖能力。當(dang)控(kong)制脈(mo)(mo)沖(chong)停止輸入，而讓后一個(ge)脈(mo)(mo)沖(chong)控(kong)制的(de)(de)繞組繼續通直流電時，則(ze)電機(ji)可以保持在固定的(de)(de)位(wei)(wei)置上(shang)，即(ji)停在后一個(ge)脈(mo)(mo)沖(chong)控(kong)制的(de)(de)角位(wei)(wei)移的(de)(de)終點位(wei)(wei)置上(shang)，這樣，步進(jin)電機(ji)可以實(shi)現停車時轉子定位(wei)(wei)。
