 DKC02.3-040-7-FW力士樂伺服驅(qū)動 伺服驅(qū)動器（servo drives）又稱為“伺服控制器”、“伺服放大器”，是用來控制伺服電機(jī)的一種控制器，其作用類似于變頻器作用于普通交流馬達(dá)，屬于伺服系統(tǒng)的一部分，主要應(yīng)用于高精度的定位系統(tǒng)。一般是通過位置、速度和力矩三種方式對伺服馬達(dá)進(jìn)行控制，實(shí)現(xiàn)高精度的傳動系統(tǒng)定位，目前是傳動技術(shù)的高端產(chǎn)品。

目前主流的伺服驅(qū)動器均采用數(shù)字信號處理器（DSP）作為控制核心，可以實(shí)現(xiàn)比較復(fù)雜的控制算法，實(shí)現(xiàn)數(shù)字化、網(wǎng)絡(luò)化和智能化。功率器件普遍采用以智能功率模塊（IPM）為核心設(shè)計(jì)的驅(qū)動電路,IPM內(nèi)部集成了驅(qū)動電路,同時(shí)具有過電壓、過電流、過熱、欠壓等故障檢測保護(hù)電路,在主回路中還加入軟啟動電路,以減小啟動過程對驅(qū)動器的沖擊。功率驅(qū)動單元首先通過三相全橋整流電路對輸入的三相電或者市電進(jìn)行整流，得到相應(yīng)的直流電。經(jīng)過整流好的三相電或市電，再通過三相正弦PWM電壓型逆變器變頻來驅(qū)動三相永磁式同步交流伺服電機(jī)。功率驅(qū)動單元的整個(gè)過程可以簡單的說就是AC-DC-AC的過程。整流單元（AC-DC）主要的拓?fù)潆娐肥侨嗳珮虿豢卣麟娐贰?
