2、同步型
同步型交流伺服電動(dòng)機(jī)雖較感應(yīng)電動(dòng)機(jī)復(fù)雜,但比直流電動(dòng)機(jī)簡(jiǎn)單。它的定子與感應(yīng)電動(dòng)機(jī)一樣,都在定子上裝有對(duì)稱三相繞組。而轉(zhuǎn)子卻不同,按不同的轉(zhuǎn)子結(jié)構(gòu)又分電磁式及非電磁式兩大類。非電磁式又分為磁滯式、永磁式和反應(yīng)式多種。其中磁滯式和反應(yīng)式同步電動(dòng)機(jī)存在效率低、功率因數(shù)較差、制造容量不大等缺點(diǎn)。數(shù)控機(jī)床中多用永磁式同步電動(dòng)機(jī)。與電磁式相比,永磁式優(yōu)點(diǎn)是結(jié)構(gòu)簡(jiǎn)單、運(yùn)行可靠、效率較高;缺點(diǎn)是體積大、啟動(dòng)特性欠佳。但永磁式同步電動(dòng)機(jī)采用高剩磁感應(yīng),高矯頑力的稀土類磁鐵后,可比直流電動(dòng)外形尺寸約小1/2,質(zhì)量減輕60﹪,轉(zhuǎn)子慣量減到直流電動(dòng)機(jī)的1/5。它與異步電動(dòng)機(jī)相比,由于采用了永磁鐵勵(lì)磁,消除了勵(lì)磁損耗及有關(guān)的雜散損耗,所以效率高。又因?yàn)闆]有電磁式同步電動(dòng)機(jī)所需的集電環(huán)和電刷等,其機(jī)械可靠性與感應(yīng)(異步)電動(dòng)機(jī)相同,而功率因數(shù)卻大大高于異步電動(dòng)機(jī),從而使永磁同步電動(dòng)機(jī)的體積比異步電動(dòng)機(jī)小些。這是因?yàn)樵诘退贂r(shí),感應(yīng)(異步)電動(dòng)機(jī)由于功率因數(shù)低,輸出同樣的有功功率時(shí),它的視在功率卻要大得多,而電動(dòng)機(jī)主要尺寸是據(jù)視在功率而定的。

3.現(xiàn)代交流伺服系統(tǒng),在經(jīng)歷了從模擬到數(shù)字化的轉(zhuǎn)變后,其內(nèi)部數(shù)字控制環(huán)已經(jīng)無處不在,比如換相、電流、速度和位置控制等;其實(shí)現(xiàn)主要通過功率半導(dǎo)體器件,像高性能DSP加FPGA、甚至伺服專用模塊也不足為奇。且新的功率器件或模塊每2~2.5年就會(huì)更新一次,新的軟件算法也日新月異,廠商的伺服產(chǎn)品大概每5年亦會(huì)更新?lián)Q代——總而言之,產(chǎn)品生命周期越來越短,變化越來越快??偨Y(jié)伺服廠家的技術(shù)路線和產(chǎn)品路線,結(jié)合市場(chǎng)需求的變化,可以看到以下一些伺服電機(jī)系統(tǒng)的發(fā)展趨勢(shì):
率化
盡管化一直都是伺服系統(tǒng)重要的發(fā)展課題,但是仍需要繼續(xù)加強(qiáng)。主要包括電機(jī)本身的率:比如永磁材料性能的改進(jìn)和更好的磁鐵安裝結(jié)構(gòu)設(shè)計(jì);也包括驅(qū)動(dòng)系統(tǒng)的率化:包括逆變器驅(qū)動(dòng)電路的優(yōu)化,加減速運(yùn)動(dòng)的優(yōu)化,再生制動(dòng)和能量反饋以及更好的冷卻方式等。
