永磁交流伺服電動(dòng)機(jī)
20世紀(jì)80年代以來，隨著集成電路、電力電子技術(shù)和交流可變速驅(qū)動(dòng)技術(shù)的發(fā)展，永磁交流伺服驅(qū)動(dòng)技術(shù)有了突出的發(fā)展，各國(guó)電氣廠商相繼推出各自的交流伺服電動(dòng)機(jī)和伺服驅(qū)動(dòng)器系列產(chǎn)品并不斷完善和更新。交流伺服系統(tǒng)已成為當(dāng)代高性能伺服系統(tǒng)的主要發(fā)展方向，使原來的直流伺服面臨被淘汰的危機(jī)。90年代以后，各國(guó)已經(jīng)商品化了的交流伺服系統(tǒng)是采用全數(shù)字控制的正弦波電動(dòng)機(jī)伺服驅(qū)動(dòng)。交流伺服驅(qū)動(dòng)裝置在傳動(dòng)領(lǐng)域的發(fā)展日新月異。永磁交流伺服電動(dòng)機(jī)同直流伺服電動(dòng)機(jī)比較，主要優(yōu)點(diǎn)有：
?、艧o電刷和換向器，因此工作可靠，對(duì)維護(hù)和保養(yǎng)要求低。

伺服的基本概念是準(zhǔn)確、、快速定位。變頻是伺服控制的一個(gè)必須的內(nèi)部環(huán)節(jié)，伺服驅(qū)動(dòng)器中同樣存在變頻（要進(jìn)行無級(jí)調(diào)速）。但伺服將電流環(huán)速度環(huán)或者位置環(huán)都閉合進(jìn)行控制，這是很大的區(qū)別。除此外，伺服電機(jī)的構(gòu)造與普通電機(jī)是有區(qū)別的，要滿足快速響應(yīng)和準(zhǔn)確定位?，F(xiàn)在市面上流通的交流伺服電機(jī)多為永磁同步交流伺服，但這種電機(jī)受工藝限制，很難做到很大的功率，十幾KW以上的同步伺服價(jià)格及其昂貴，這樣在現(xiàn)場(chǎng)應(yīng)用允許的情況下多采用交流異步伺服，這時(shí)很多驅(qū)動(dòng)器就是高端變頻器，帶編碼器反饋閉環(huán)控制。所謂伺服就是要滿足準(zhǔn)確、、快速定位，只要滿足就不存在伺服變頻之爭(zhēng)。
