從應用角度而言，兩者各自優勢可以從速度穩定性、加載負載穩定性、控制對象上進行對比。伺服驅動器一般控制同步電機，變頻器一般控制異步電機。變頻器主要功能是調速，伺服在調速、定位、精度上更高，功能也更強大。對升降速、高速啟停、轉矩控制要求非常高的行業與領域，伺服比變頻有著明顯的優勢。當然，從控制原理上來講，如果變頻器匹配相應的編碼器，也可以達到直流無刷矢量伺服電機的性能要求。
伺服驅動器發展了變頻技術，在驅動器內部的電流環，速度環和位置環(變頻器沒有該環)都進行了比一般變頻更的控制技術和算法運算，主要的一點可以進行的位置控制。
近年來，高端變頻技術在不斷發展，配合機電時間常數小的電機也能完成伺服的定位跟蹤工程，特別是在大功率場合，伺服本身的功能就是快速定位跟蹤，變頻器做到這個程度那就是伺服了，目前從企業的發展來看，變頻器廠家推出伺服產品，無論是在技術基礎還是在銷售渠道商都占據一定的優勢，已經成為越來越多的變頻器廠家的發展方向。

L形結構件的有限元模型如圖2所示。為分析結構的不同鋪層方向對制造過程中回彈變形的影響，比較了L型結構的[]8，[/45/9/-45]2s及[9]8三種鋪層情況，結果如圖3所示，可見不同鋪層方向對回彈角的影響較大。出現這樣的變化趨勢的原因是不同鋪層的層合板L形構件在拐角處的徑向及周向熱應變及曲率收縮應變不同。對[/45/9/-45]2s種鋪層，改變L形結構件的厚度,模擬回彈角度的變化，結果如圖4所示，可見厚度的改變對回彈角的影響也很明顯，隨著厚度的增加，回彈角變小。

其實各位都忽略了一個問題，就是伺服電機都是同步電機，其轉子轉速就是電機的實際轉速，不存在速度差，而變頻器控制對象是異步電機，其實際轉速跟轉子轉速存在著轉差，所以它本身電機在速度就不是很穩定。
伺服的基本概念是準確、、快速定位。變頻僅僅是伺服控制的一個必須的內部環節，伺服驅動器中同樣存在變頻(要進行無級調速)。但伺服將電流環速度環或者位置環都閉合進行控制，這是很大的區別。除此外，伺服電機的構造與普通電機是有區別的，要滿足快速響應和準確定位。同步伺服的成本價格及其昂貴，這樣在現場應用允許的情況下多采用交流異步伺服，這時很多驅動器就是高端變頻器，帶編碼器反饋閉環控制。所謂伺服就是要滿足準確、、快速定位，所以往往只有高端的產品才采用伺服系統。
