①有刷電機成本低，結(jié)構(gòu)簡單，啟動轉(zhuǎn)矩大，調(diào)速范圍寬，控制容易，需要維護，但維護不方便（換碳刷），產(chǎn)生電磁干擾，對環(huán)境有要求。因此它可以用于對成本敏感的普通工業(yè)和民用場合。 ②無刷電機體積小，重量輕，出力大，響應(yīng)快，速度高，慣量小，轉(zhuǎn)動平滑，力矩穩(wěn)定?？刂茝?fù)雜，容易實現(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。電機免維護，效率很高，運行溫度低，電磁輻射很小，長壽命，可用于各種環(huán)境。</p><p> 直流電機具有響應(yīng)快速、較大的起動轉(zhuǎn)矩、從零轉(zhuǎn)速至額定轉(zhuǎn)速具備可提供額定轉(zhuǎn)矩的性能，但直流電機的優(yōu)點也正是它的缺點，由于直流電機要產(chǎn)生額定負載下恒定轉(zhuǎn)矩的性能，則電樞磁場與轉(zhuǎn)子磁場須恒維持90°，這就要藉由碳刷及整流子。碳刷及整流子在電機轉(zhuǎn)動時會產(chǎn)生火花、碳粉因此除了會造成組件損壞之外，使用場合也受到限制。交流電機沒有碳刷及整流子，免維護、堅固、應(yīng)用廣，但性能上若要達到相當于直流電機的性能須用復(fù)雜控制技術(shù)才能達到。

style="text-indent:25px">伺服電機是指在伺服系統(tǒng)中控制機械元件運轉(zhuǎn)的發(fā)動機，是一種補助馬達間接變速裝置。伺服電機可使控制速度，位置精度非常準確，可以將電壓信號轉(zhuǎn)化為轉(zhuǎn)矩和轉(zhuǎn)速以驅(qū)動控制對象。伺服電機轉(zhuǎn)子轉(zhuǎn)速受輸入信號控制，并能快速反應(yīng)，在自動控制系統(tǒng)中，用作執(zhí)行元件，并且具有機電時間常數(shù)小、線性度高、始動電壓等特性，能夠把所收到的電信號轉(zhuǎn)換成電動機軸上的角位移或角速度輸出。分為直流和交流伺服電動機兩大類，其主要特點是，當信號電壓為零時無自轉(zhuǎn)情況，轉(zhuǎn)速隨著轉(zhuǎn)矩的增加而勻速下降。德國EMG電機</p><p
