西門(mén)子伺服電機(jī)作為一種數(shù)字式執(zhí)行元件，在運(yùn)動(dòng)控制系統(tǒng)中得到廣泛的應(yīng)用。在使用西門(mén)子電機(jī)的時(shí)候，感覺(jué)電機(jī)工作時(shí)有較大的發(fā)熱。實(shí)際上發(fā)熱是電機(jī)的一個(gè)普遍現(xiàn)象，但怎樣的發(fā)熱程度才算正常，以及如何盡量減小步進(jìn)電機(jī)發(fā)熱呢?

　　1、將西門(mén)子電機(jī)發(fā)熱控制在合理范圍內(nèi)

　　電機(jī)發(fā)熱允許到什么程度，主要取決于電機(jī)內(nèi)部絕緣等級(jí)。內(nèi)部絕緣性能在高溫下(130度以上)才會(huì)被破壞。低于130度，電機(jī)不會(huì)損壞，表面溫度會(huì)在90度以下。表面溫度在70-80度都是正常的。滴幾滴水迅速氣化，則90度以上了;當(dāng)然也可以用測(cè)溫槍來(lái)檢測(cè)。

　　2、西門(mén)子電機(jī)發(fā)熱隨速度變化的情況

　　采用恒流驅(qū)動(dòng)技術(shù)時(shí)，電機(jī)在靜態(tài)和低速下，電流會(huì)維持相對(duì)恒定，以保持恒力矩輸出。速度高到一定程度，電機(jī)內(nèi)部反電勢(shì)升高，電流將逐步下降，力矩也會(huì)下降。

　　3、發(fā)熱帶來(lái)的影響

　　電機(jī)發(fā)熱雖然一般不會(huì)影響電機(jī)的壽命，對(duì)大多數(shù)客戶(hù)來(lái)說(shuō)沒(méi)必要理會(huì)。嚴(yán)重的發(fā)熱會(huì)帶來(lái)一些負(fù)面影響。如電機(jī)內(nèi)部各部分熱膨脹系數(shù)不同導(dǎo)致結(jié)構(gòu)應(yīng)力的變化和內(nèi)部氣隙的微小變化，會(huì)影響電機(jī)的動(dòng)態(tài)響應(yīng)，高速會(huì)容易失步。

　　4、減少電機(jī)的發(fā)熱

　　減少發(fā)熱，就是減少銅損和鐵損。 減少銅損有兩個(gè)方向，減少電阻和電流，這就要求在選型時(shí)盡量選擇電阻小和額定電流小的電機(jī)，對(duì)兩相電機(jī)，能用串聯(lián)的電機(jī)就不用并聯(lián)電機(jī)。細(xì)分驅(qū)動(dòng)器由于電流波形接近正弦，諧波少，電機(jī)發(fā)熱也會(huì)較少。 減少鐵損的辦法不多，電壓等級(jí)與之有關(guān)，高壓驅(qū)動(dòng)的電機(jī)雖然會(huì)帶來(lái)高速特性的提升，但也帶來(lái)發(fā)熱的增加。
