作為紡織設(shè)備的主要機(jī)型，以往的玻纖捻線機(jī)升降系統(tǒng)主要通過機(jī)械凸輪實現(xiàn)成型。如過工藝參數(shù)發(fā)生變化，只能通過更換機(jī)械凸輪的方式實現(xiàn)，更換周期長，操作過程復(fù)雜。也有部分捻線機(jī)采用步進(jìn)電機(jī)代替機(jī)械凸輪來實現(xiàn)系統(tǒng)升降功能，但是有一定的局限性：

作為紡織設(shè)備的主要機(jī)型，以往的玻纖捻線機(jī)升降系統(tǒng)主要通過機(jī)械凸輪實現(xiàn)成型。如過工藝參數(shù)發(fā)生變化，只能通過更換機(jī)械凸輪的方式實現(xiàn)，更換周期長，操作過程復(fù)雜。也有部分捻線機(jī)采用步進(jìn)電機(jī)代替機(jī)械凸輪來實現(xiàn)系統(tǒng)升降功能，但是有一定的局限性：
1. 凸輪需要連續(xù)變速，而步進(jìn)電機(jī)響應(yīng)較慢。為了適應(yīng)步進(jìn)電機(jī)的特性，升降時的連續(xù)變速只能改為恒轉(zhuǎn)速，但是取消了變速的功能，紗形和卷裝量都受到影響，不利于退解，降低了卷裝量;
2. 步進(jìn)電機(jī)隨著轉(zhuǎn)速提高，力矩下降很快;
3. 步進(jìn)電機(jī)一般溫升較高，影響了整個電氣系統(tǒng)的穩(wěn)定運行時間。
