滾珠絲杠在機(jī)床行業(yè)的普遍應(yīng)用，推動了加工機(jī)床行業(yè)的快速發(fā)展，但機(jī)械式傳動的局限性，已無法應(yīng)對日益高速化、高效化切削的發(fā)展趨勢。直線電動機(jī)式就是在這種趨勢的需求下產(chǎn)生的一種高速高效傳動方式，特別是機(jī)床的高速傳動發(fā)展跨上一個(gè)新臺階。德國作為世界先進(jìn)機(jī)床的先驅(qū)，20世紀(jì)80年代就開始了高速銑削和車削技術(shù)的研發(fā)。1993年，德國EXCELLO公司推出了世界上第一個(gè)由直線電動機(jī)驅(qū)動的工作臺HSC-240型高速加工中心，機(jī)床主軸最高速達(dá)到24 000r/min，最大進(jìn)給速度為60n/min，加速度達(dá)到1g。

當(dāng)進(jìn)給速度為20m/min時(shí)，其輪廓精度可達(dá)0.004mm。美國的Ingersoll公司緊接著推出了HVM-800型高速加工中心，最大進(jìn)給速度達(dá)到75.20m/m i n。

1996年開始，日本相繼研制成功采用直線電動機(jī)的臥式加工中心、高速機(jī)床、超高速小型加工中心、超精密鏡面加工機(jī)床、高速成形機(jī)床等。從此以后，直線電動機(jī)在高速數(shù)控機(jī)床的應(yīng)用如雨后春筍般地迅速發(fā)展起來。近十年來，世界上各工業(yè)發(fā)達(dá)國家紛紛投入巨資，大力研究、開發(fā)成功不少直線電動機(jī)驅(qū)動的高速數(shù)控機(jī)床，并逐漸有搶占傳統(tǒng)滾珠絲杠市場的態(tài)勢。

直線電動機(jī)加工中心在國外的寶馬、通用等著名汽車公司已經(jīng)有成熟的應(yīng)用，在國內(nèi)上汽通用、東風(fēng)雪鐵龍、昌河鈴木、海馬汽車等也有整線的應(yīng)用實(shí)例。本文從技術(shù)分析和應(yīng)用實(shí)例上進(jìn)行了直線電動機(jī)和滾珠絲杠驅(qū)動加工中心的對比。圖1為Comau Urane25直線電動機(jī)高速加工中心。
傳動原理分析對比滾珠杠副存任的問題如下：

（1）“旋轉(zhuǎn)電動機(jī)+滾珠絲杠副”的直線驅(qū)動方式存在著多個(gè)彈性環(huán)節(jié)，當(dāng)整個(gè)系統(tǒng)在高速運(yùn)動時(shí)，會出現(xiàn)剛度下降，同時(shí)彈性變形使系統(tǒng)的階次變高，系統(tǒng)的魯棒性降低，從而使伺服性能下降。彈性變形是數(shù)控機(jī)床產(chǎn)生機(jī)械諧振的根源。

（2）中間傳動環(huán)節(jié)的存在，增加了運(yùn)動體的慣量，使得位移和速度響應(yīng)變慢。

（3）間隙死區(qū)、摩擦、誤差積累等因素，使進(jìn)給速度和加速度受到限制。

（4）動轉(zhuǎn)平穩(wěn)性較差，在高速運(yùn)動下噪聲易發(fā)熱。

（5）精度保持壽命相對短。
而直線電動機(jī)以—個(gè)運(yùn)動部件實(shí)現(xiàn)直線運(yùn)動，則具有以下優(yōu)點(diǎn)：直接驅(qū)動中力是無接觸傳遞的，因此無磨損，使用壽命長，維護(hù)簡單；傳動剛性高，推力平穩(wěn)，直接驅(qū)動，彈性環(huán)節(jié)減少，系統(tǒng)剛性提高，傳動效果高；定位精度和重復(fù)定位精度高，可達(dá)亞微米級，比伺服電動機(jī)及滾珠絲杠副傳動的加速度和重復(fù)定位精度提高7～10 倍。
