博世力士樂Rexroth驅(qū)動(dòng)器DKC02.3-100-7，REXROTH伺服驅(qū)動(dòng)器工作原理：
目前主流的伺服驅(qū)動(dòng)器均采用數(shù)字信號(hào)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(dòng)電路,IPM內(nèi)部集成了驅(qū)動(dòng)電路,同時(shí)具有過電壓、過電流、過熱、欠壓等故障檢測(cè)保護(hù)電路,在主回路中還加入軟啟動(dòng)電路,以減小啟動(dòng)過程對(duì)驅(qū)動(dòng)器的沖擊。功率驅(qū)動(dòng)單元首先通過三相全橋整流電路對(duì)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(lái)驅(qū)動(dòng)三相永磁式同步交流伺服電機(jī)。功率驅(qū)動(dòng)單元的整個(gè)過程可以簡(jiǎn)單的說(shuō)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?br />隨著伺服系統(tǒng)的大規(guī)模應(yīng)用，伺服驅(qū)動(dòng)器使用、伺服驅(qū)動(dòng)器調(diào)試、伺服驅(qū)動(dòng)器維修都是伺服驅(qū)動(dòng)器在當(dāng)今比較重要的技術(shù)課題，越來(lái)越多工控技術(shù)服務(wù)商對(duì)伺服驅(qū)動(dòng)器進(jìn)行了技術(shù)深層次研究。
博世力士樂Rexroth驅(qū)動(dòng)器DKC02.3-100-7，REXROTH伺服進(jìn)給系統(tǒng)要求：
1、調(diào)速范圍寬
2、定位精度高
3、有足夠的傳動(dòng)剛性和高的速度穩(wěn)定性
4、快速響應(yīng)，無(wú)超調(diào)
為了保證生產(chǎn)率和加工質(zhì)量，除了要求有較高的定位精度外，還要求有良好的快速響應(yīng)特性，即要求跟蹤指令信號(hào)的響應(yīng)要快，因?yàn)閿?shù)控系統(tǒng)在啟動(dòng)、制動(dòng)時(shí)，要求加、減加速度足夠大，縮短進(jìn)給系統(tǒng)的過渡過程時(shí)間，減小輪廓過渡誤差。
5、低速大轉(zhuǎn)矩，過載能力強(qiáng)
一般來(lái)說(shuō)，伺服驅(qū)動(dòng)器具有數(shù)分鐘甚至半小時(shí)內(nèi)1.5倍以上的過載能力，在短時(shí)間內(nèi)可以過載4～6倍而不損壞。
6、可靠性高
要求數(shù)控機(jī)床的進(jìn)給驅(qū)動(dòng)系統(tǒng)可靠性高、工作穩(wěn)定性好，具有較強(qiáng)的溫度、濕度、振動(dòng)等環(huán)境適應(yīng)能力和很強(qiáng)的抗干擾的能力。
對(duì)電機(jī)的要求
1、從zui低速到zui高速電機(jī)都能平穩(wěn)運(yùn)轉(zhuǎn)，轉(zhuǎn)矩波動(dòng)要小，尤其在低速如0.1r/min或更低速時(shí)，仍有平穩(wěn)的速度而無(wú)爬行現(xiàn)象。
2、電機(jī)應(yīng)具有大的較長(zhǎng)時(shí)間的過載能力，以滿足低速大轉(zhuǎn)矩的要求。一般直流伺服電機(jī)要求在數(shù)分鐘內(nèi)過載4～6倍而不損壞。
3、為了滿足快速響應(yīng)的要求，電機(jī)應(yīng)有較小的轉(zhuǎn)動(dòng)慣量和大的堵轉(zhuǎn)轉(zhuǎn)矩，并具有盡可能小的時(shí)間常數(shù)和啟動(dòng)電壓。
4、電機(jī)應(yīng)能承受頻繁啟、制動(dòng)和反轉(zhuǎn)。
