變頻器和軟啟動器是兩種完全不同用途的產品。變頻器主要是用于需要電動機調速的地方，因此也被稱為變頻調速器，其輸出不但改變電壓而且同時改變頻率。變頻器具備所有軟啟動器和其他啟動控制裝置的功能，且啟動特性上較之其他電動機啟動裝置有比較大的優(yōu)勢.因此完全可以用作電動機的軟啟動控制。但之所以目前在電動機的啟動控制領城軟啟動器仍占據主要位置.是由于變頻器固有的一些劣勢，且短期內很難克服.只有克服了這些劣勢之后.變頻器才有可能取代軟啟動器。變頻器的特點如下。(1)啟動轉矩大，功率因數高。因為電動機的功率因數與工作頻率有關，在電動機低速運行時工頻電源下的功率因數遠低于低頻電源下的功率因數。變頻器可以控制電動機從低頻起步.且在整個啟動過程中在接近額定電流的條件下始終保持比較高的功率因數和接近額定轉矩的輸出轉矩。(2)輕載或空載條件下.或啟動期間采取減載卸載等措施時.變頻器容量可以比電動機容量小。當然，啟動完成后變頻器需要退出運行。(3)啟動電流小。變頻器一電動機拖動系統(tǒng)允許的啟動時間可以很長。因為在這期間，電動機電流可以不超過電動機額定電流，因此，不論是變頻器、電動機還是其他元器件均沒有超常地發(fā)熱。

軟起動器就是應用**效用**突出的控制設備,軟啟動器在不同領域、不同行業(yè)甚至是不同設備上的應用往往也有著極大的不同。1、軟起動器在城市雨水排污泵站、污水處理廠中的應用雨水排污站的泄水池是雨水、生活污水、工業(yè)污水的集中地，為確保泄水池液位保持在允許的范圍內，通過檢測泄水池液位來自動控制排污泵組工作以保證污水的正常排放。2、軟起動器應用于自來水廠、加壓泵站清水泵主要實現大功率水泵電機的軟起動、軟停車，重點消除、減弱水錘的危害。當液體在管路系統(tǒng)中受外力突然加速或突然減速、或改變流向就會造成水錘，水錘危害很大，輕則引起管路，系統(tǒng)振動，發(fā)出噪聲，重則造成損壞，甚至使泵房被淹。3、軟起動器在消防泵控制中的應用消火栓泵、噴淋泵是工業(yè)和民用建筑消防設施的重要消防裝備，其運行可靠性極其重要，隨著大中型建設項目的興建，所配置的消火栓泵、噴淋泵功率、揚程增大，傳統(tǒng)的降壓起動方式凸顯其缺點，尤其高層建筑水錘危害嚴重，給設備運行帶來不安全因素，目前軟起動在消防泵控制中得到的應用。4、軟起動器在在各種類型的深井潛水泵、長軸泵中的應用一般深井潛水泵揚程較大，非軟停機時水錘現象明顯。
