　　關(guān)于交流伺服電機(jī)的幾個(gè)問題：
　　問（A）：交流同步伺服、交流異步伺服的額定轉(zhuǎn)速與極數(shù)是否有關(guān)？n1=60f/2p？額定轉(zhuǎn)速以下輸出恒轉(zhuǎn)矩，額定轉(zhuǎn)速以上恒功率，那么額定轉(zhuǎn)速的界定是由電機(jī)本身的機(jī)械決定還是驅(qū)動(dòng)器來決定？
　　有關(guān)，同步轉(zhuǎn)速n1=60f/2p，異步機(jī)還有滑差s，n=(1-s)n1，同步機(jī)n=n1，2p為極對(duì)數(shù)。控制中弱磁速度的界定是由驅(qū)動(dòng)器判斷的。
　　額定轉(zhuǎn)速可以由幾個(gè)方面決定：同步伺服的反電勢(shì)高低、電機(jī)鐵心材料允許的驅(qū)動(dòng)電流交變頻率、額定轉(zhuǎn)矩下電機(jī)的功率、溫升等，主要還是反電勢(shì)；異步電機(jī)主要受材料允許的頻率以及極對(duì)數(shù)限制。
額定轉(zhuǎn)速的界定由電機(jī)本身的機(jī)械和電器特性來決定。

減速機(jī)是一種常見的動(dòng)力傳達(dá)機(jī)構(gòu)，在各種機(jī)械傳動(dòng)系統(tǒng)中都有應(yīng)用。減速機(jī)的安裝和使用一定要符合技術(shù)規(guī)范和標(biāo)準(zhǔn)，這直接關(guān)系到減速機(jī)的運(yùn)行效果。
1、減速機(jī)在安裝時(shí)，要特別注意傳動(dòng)中心軸線的對(duì)中，對(duì)中的誤差不能超過減速機(jī)所用聯(lián)軸器的使用補(bǔ)償量。減速機(jī)按照要求對(duì)中之后，可以獲得更理想的傳動(dòng)效果和更長(zhǎng)久的使用壽命。
2、在減速機(jī)的輸出軸上安裝傳動(dòng)件時(shí)，必須注意操作的柔和，禁止使用錘子等工具粗暴安裝，是利用裝配夾具和軸端的內(nèi)螺紋進(jìn)行安裝，以螺栓擰入的力度將傳動(dòng)件壓入減速機(jī)軸，這樣可以保護(hù)減速機(jī)內(nèi)部零件不會(huì)受到損壞。
3、減速機(jī)所采用的聯(lián)軸器有多種類型可選，但不要使用鋼性固定式聯(lián)軸器，這類聯(lián)軸器沒有徑向偏移補(bǔ)償量而且安裝比較困難，一旦安裝不當(dāng)就會(huì)加大載荷量，容易造成軸承的損壞，甚至?xí)�造成輸出軸的斷裂。
