滾珠絲杠進(jìn)給傳動(dòng)方式，由于受自身結(jié)構(gòu)的限制，在進(jìn)給速度、加速度、快速定位精度等方面很難有突破性的提高，已無(wú)法滿足超高速切削、超精密加工對(duì)機(jī)床進(jìn)給系統(tǒng)伺服性能提出的更高要求。直線電機(jī)將電能直接轉(zhuǎn)換成直線運(yùn)動(dòng)機(jī)械能，不需要任何中間轉(zhuǎn)換機(jī)構(gòu)的傳動(dòng)裝置。具有起動(dòng)推力大、傳動(dòng)剛度高、動(dòng)態(tài)響應(yīng)快、定位精度高、行程長(zhǎng)度不受限制等優(yōu)點(diǎn)。在機(jī)床進(jìn)給系統(tǒng)中，采用直線電動(dòng)機(jī)直接驅(qū)動(dòng)與原旋轉(zhuǎn)電機(jī)傳動(dòng)的較大區(qū)別是取消了從電機(jī)到工作臺(tái)（拖板）之間的機(jī)械傳動(dòng)環(huán)節(jié)，把機(jī)床進(jìn)給傳動(dòng)鏈的長(zhǎng)度縮短為零，因而這種傳動(dòng)方式又被稱(chēng)為“零傳動(dòng)”。正是由于這種零傳動(dòng)方式,帶來(lái)了原旋轉(zhuǎn)電機(jī)驅(qū)動(dòng)方式無(wú)法達(dá)到的性能指標(biāo)和優(yōu)點(diǎn)。</p><p
