直線電機的高速運動原理，中(zhong)間(jian)轉換(huan)(huan)裝(zhuang)置(zhi)有哪些優點，下面詳細介紹(shao)下。我們在很(hen)多(duo)場合都可(ke)以看到(dao)，很(hen)多(duo)直線傳動裝(zhuang)置(zhi)或系統(tong)是由旋轉電機，通(tong)過中(zhong)間(jian)轉換(huan)(huan)設備轉換(huan)(huan)成直線運動的。考慮到(dao)這類設備或系統(tong)有著中(zhong)間(jian)傳遞結構，所(suo)以整個機械存在體積較大、效率低(di)、精度低(di)等問題。

 直(zhi)線(xian)(xian)(xian)(xian)電(dian)(dian)機(ji)的(de)(de)(de)(de)(de)發展迅速(su)(su)，在各個領域得到了(le)廣(guang)泛地應用，直(zhi)線(xian)(xian)(xian)(xian)電(dian)(dian)機(ji)的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)速(su)(su)通常是(shi)指直(zhi)線(xian)(xian)(xian)(xian)轉(zhuan)(zhuan)速(su)(su)，相當于(yu)旋(xuan)轉(zhuan)(zhuan)電(dian)(dian)機(ji)的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)速(su)(su)。直(zhi)線(xian)(xian)(xian)(xian)電(dian)(dian)機(ji)的(de)(de)(de)(de)(de)速(su)(su)度(du)遠(yuan)高于(yu)旋(xuan)轉(zhuan)(zhuan)電(dian)(dian)機(ji)，通過機(ji)械部(bu)件的(de)(de)(de)(de)(de)直(zhi)線(xian)(xian)(xian)(xian)位移運動(dong)的(de)(de)(de)(de)(de)速(su)(su)度(du)。直(zhi)線(xian)(xian)(xian)(xian)電(dian)(dian)機(ji)的(de)(de)(de)(de)(de)應用與(yu)旋(xuan)轉(zhuan)(zhuan)電(dian)(dian)機(ji)有(you)所(suo)不同(tong)，與(yu)負(fu)載有(you)很大的(de)(de)(de)(de)(de)關系。通常沒有(you)負(fu)載的(de)(de)(de)(de)(de)直(zhi)線(xian)(xian)(xian)(xian)運動(dong)的(de)(de)(de)(de)(de)速(su)(su)度(du)，普通的(de)(de)(de)(de)(de)旋(xuan)轉(zhuan)(zhuan)電(dian)(dian)機(ji)的(de)(de)(de)(de)(de)轉(zhuan)(zhuan)速(su)(su)受(shou)到離心力的(de)(de)(de)(de)(de)限制(zhi)，直(zhi)線(xian)(xian)(xian)(xian)電(dian)(dian)機(ji)在運行時，其部(bu)件和傳動(dong)裝置與(yu)旋(xuan)轉(zhuan)(zhuan)電(dian)(dian)機(ji)不同(tong)，因(yin)此直(zhi)線(xian)(xian)(xian)(xian)轉(zhuan)(zhuan)速(su)(su)不受(shou)限制(zhi)。

 考慮到直(zhi)線(xian)電機(ji)的(de)技術高(gao)，制(zhi)造(zao)工(gong)藝和材(cai)料成(cheng)本較高(gao)，這不(bu)僅(jin)是因(yin)為永磁材(cai)料的(de)成(cheng)本高(gao)。也是因(yin)為制(zhi)造(zao)直(zhi)線(xian)電機(ji)對(dui)加工(gong)成(cheng)本的(de)設(she)備有要(yao)求(qiu)，比如如何保證長行程的(de)加工(gong)精度，都(dou)需要(yao)精密(mi)的(de)數控機(ji)床(chuang)來完成(cheng)。

 直(zhi)(zhi)線(xian)電(dian)(dian)機(ji)(ji)采用全閉環控(kong)制，是(shi)(shi)(shi)指(zhi)電(dian)(dian)機(ji)(ji)在(zai)本(ben)體上(shang)裝(zhuang)有光(guang)柵(zha)尺(chi)，將(jiang)力(li)(li)矩(ju)反饋到執行器的位置，因為光(guang)柵(zha)尺(chi)的位置精度高，所以(yi)直(zhi)(zhi)線(xian)電(dian)(dian)機(ji)(ji)的驅(qu)動(dong)(dong)負載，可以(yi)提(ti)高控(kong)制精度。與(yu)標(biao)準伺服驅(qu)動(dong)(dong)直(zhi)(zhi)線(xian)運(yun)(yun)(yun)動(dong)(dong)相比，該傳(chuan)(chuan)動(dong)(dong)裝(zhuang)置由直(zhi)(zhi)線(xian)電(dian)(dian)機(ji)(ji)驅(qu)動(dong)(dong)，不需(xu)要轉(zhuan)化(hua)裝(zhuang)置，直(zhi)(zhi)接(jie)(jie)產(chan)生推(tui)力(li)(li)，簡化(hua)系統，保證運(yun)(yun)(yun)行的可靠性，提(ti)高了傳(chuan)(chuan)動(dong)(dong)效率(lv)，降低制造成本(ben)，便(bian)于維(wei)護。直(zhi)(zhi)線(xian)電(dian)(dian)機(ji)(ji)是(shi)(shi)(shi)由電(dian)(dian)能直(zhi)(zhi)接(jie)(jie)產(chan)生的直(zhi)(zhi)線(xian)電(dian)(dian)磁(ci)推(tui)力(li)(li)，在(zai)驅(qu)動(dong)(dong)設(she)備中，運(yun)(yun)(yun)動(dong)(dong)可以(yi)無機(ji)(ji)械接(jie)(jie)觸(chu)，使傳(chuan)(chuan)動(dong)(dong)部件無磨損，從而(er)減少了機(ji)(ji)械損耗，直(zhi)(zhi)線(xian)電(dian)(dian)機(ji)(ji)驅(qu)動(dong)(dong)的磁(ci)懸浮列車就是(shi)(shi)(shi)這種(zhong)情況。普通伺服直(zhi)(zhi)線(xian)運(yun)(yun)(yun)動(dong)(dong)的機(ji)(ji)械結(jie)構在(zai)運(yun)(yun)(yun)行時，噪聲是(shi)(shi)(shi)不可避(bi)免的。

 直線(xian)電機結構簡單(dan)，散(san)熱(re)效果更好。考(kao)慮到一(yi)次鐵芯和繞組(zu)的(de)端(duan)部都(dou)暴露在空氣中，鐵芯很(hen)長，有(you)很(hen)大(da)的(de)散(san)熱(re)面，所以直線(xian)電機的(de)熱(re)負荷可(ke)以達(da)到更高，而且不需要額外(wai)的(de)冷(leng)卻設備。

 同時(shi)，直線電機(ji)的(de)動(dong)態響應速度比普(pu)通(tong)伺(si)服驅動(dong)方式要(yao)快，用直線電機(ji)驅動(dong)，可以提高設備的(de)生(sheng)產效率。
