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。</p><p style="text-indent:25px">要讓電機轉(zhuǎn)動起來，控制部就需要按照Hall-sensor感應(yīng)到的電機轉(zhuǎn)子所在位置，然后依照定子繞線決定開啟（或關(guān)閉）換流器**率晶體管的順序，使電流依序流經(jīng)電機線圈產(chǎn)生順向（或逆向）旋轉(zhuǎn)磁場，并與轉(zhuǎn)子的磁鐵相互作用，如此就能使電機順時/逆時轉(zhuǎn)動。當電機轉(zhuǎn)子轉(zhuǎn)動到Hall-sensor感應(yīng)出另一組信號的位置時，控制部又再開啟下一組功率晶體管，如此循環(huán)電機就可以依同一方向繼續(xù)轉(zhuǎn)動直到控制部決定要電機轉(zhuǎn)子停止則關(guān)閉功率晶體管（或只開下臂功率晶體管）；要電機轉(zhuǎn)子反向則功率晶體管開啟順序相反。</p><div

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">所有家用電器在電機運行中，均產(chǎn)生不同程度的諧波電壓和電流，使電動機在非正弦電壓、電流下運行。高次諧波會引起電動機定子銅耗、轉(zhuǎn)子銅(鋁)耗、鐵耗及附加損耗的增加，較為明顯的就是轉(zhuǎn)子銅(鋁)耗。因為普通的交流異步電動機是以接近于基波頻率所對應(yīng)的同步轉(zhuǎn)速旋轉(zhuǎn)的，因此，高次諧波電壓以較大的轉(zhuǎn)差切割轉(zhuǎn)子導(dǎo)條后，便會產(chǎn)生很大的轉(zhuǎn)子損耗。除此之外，還需考慮因集膚效應(yīng)所產(chǎn)生的附加銅耗。這些損耗都會使電動機額外發(fā)熱，效率降低，輸出功率減小，但如果使用變頻電機，其能耗能減少20%-30%左右。日本東榮伺服電機價格</p><p
