何時(shí)選用直流伺服系統(tǒng)，它和交流伺服有何區(qū)別？
答：直流伺服電機(jī)分為有刷和無(wú)刷電機(jī)。
有刷電機(jī)成本低，結(jié)構(gòu)簡(jiǎn)單，啟動(dòng)轉(zhuǎn)矩大，調(diào)速范圍寬，控制容易，需要維護(hù)，但維護(hù)方便（換碳刷），產(chǎn)生電磁干擾，對(duì)環(huán)境有要求。因此它可以用于對(duì)成本敏感的普通工業(yè)和民用場(chǎng)合。
無(wú)刷電機(jī)體積小，重量輕，出力大，響應(yīng)快，速度高，慣量小，轉(zhuǎn)動(dòng)平滑，力矩穩(wěn)定?？刂茝?fù)雜，容易實(shí)現(xiàn)智能化，其電子換相方式靈活，可以方波換相或正弦波換相。電機(jī)免維護(hù)，效率很高，運(yùn)行溫度低，電磁輻射很小，長(zhǎng)壽命，可用于各種環(huán)境。

行星減速器空載力矩的測(cè)試
　　在傳統(tǒng)的行星減速機(jī)空載力矩測(cè)試時(shí)，采用在常溫下，減速器輸入端安裝力矩扳手，逐漸增加扭矩，輸出軸由靜止到轉(zhuǎn)動(dòng)，記錄扭矩值。扭矩值將呈現(xiàn)由小到大，再減小的過(guò)程。測(cè)試時(shí)輸出軸轉(zhuǎn)動(dòng)大于10轉(zhuǎn)，扭矩值的值為行星減速器空載轉(zhuǎn)動(dòng)扭矩。但是這種測(cè)試方法人為因素占很大比重，轉(zhuǎn)動(dòng)力矩扳手的速度很難控制好，由于輸入轉(zhuǎn)速會(huì)直接影響減速機(jī)的輸出力矩波動(dòng)，因此對(duì)于減速機(jī)存在微小力矩變換很難觀察出來(lái)。
　　本方法是采用一套伺服驅(qū)動(dòng)系統(tǒng)來(lái)動(dòng)態(tài)測(cè)量減速機(jī)的機(jī)械效率。用一套伺服系統(tǒng)測(cè)試減速機(jī)傳遞效率的方法，無(wú)需準(zhǔn)備專用測(cè)試平臺(tái)，只需要減速機(jī)與一套現(xiàn)有伺服驅(qū)動(dòng)裝置連接，通過(guò)測(cè)量分析力矩波動(dòng)值來(lái)對(duì)行星減速機(jī)進(jìn)行檢驗(yàn)測(cè)試。
　　方法采用計(jì)算機(jī)與控制器、驅(qū)動(dòng)器連接，驅(qū)動(dòng)器與電機(jī)連接然后電機(jī)直接與行星減速機(jī)連接，效率是行星減速機(jī)的一個(gè)重要性能指標(biāo)，但是效率需要在減速機(jī)運(yùn)行狀態(tài)下測(cè)量，一般情況下不易測(cè)量。
　　減速機(jī)的傳動(dòng)比是恒定的，即只要測(cè)出輸入、輸出軸的轉(zhuǎn)矩，就可以測(cè)出行星減速機(jī)在傳遞力矩時(shí)就產(chǎn)生變形，只要測(cè)出輸入軸（或輸出軸）兩截面的相對(duì)扭轉(zhuǎn)角，就可以測(cè)出該軸的扭矩。
