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。
