　　伺服與變頻的一個(gè)重要區(qū)別是:
　　變頻可以無編碼器,伺服則必須有編碼器,作電子換向用，交流伺服的技術(shù)本身就是借鑒并應(yīng)用了變頻的技術(shù)，在直流電機(jī)的伺服控制的基礎(chǔ)上通過變頻的PWM方式模仿直流電機(jī)的控制方式來實(shí)現(xiàn)的，也就是說交流伺服電機(jī)必然有變頻的這一環(huán)節(jié)：PLC資料變頻就是將工頻的50、60HZ的交流電先整流成直流電，然后通過可控制門極的各類晶體管(IGBT，IGCT等)通過載波頻率和PWM調(diào)節(jié)逆變?yōu)轭l率可調(diào)的波形類似于正余弦的脈動(dòng)電，由于頻率可調(diào)，所以交流電機(jī)的速度就可調(diào)了(n=60f/2p ，n轉(zhuǎn)速，f頻率， p極對(duì)數(shù))。

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：
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。
