電動機使用變頻器的作用就是為了調(diào)速，并降低啟動電流。為了產(chǎn)生可變的電壓和頻率，該設(shè)備首先要把電源的交流電變換為直流電，這個過程叫整流。一般逆變器是把直流電源逆變?yōu)橐恍┑墓潭l率和一些電壓的逆變電源。對于逆變?yōu)轭l率可調(diào)、電壓可調(diào)的逆變器我們稱為變頻器。變頻器輸出的波形是模擬正弦波，主要是用在三相異步電動機調(diào)速用，又叫變頻調(diào)速器。對于主要用在儀器儀表的檢測設(shè)備中的波形要求較高的可變頻率逆變器，要對波形進行整理，可以輸出標準的正弦波，叫變頻電源。一般變頻電源是變頻器價格的15-20倍。由于變頻器設(shè)備中產(chǎn)生變化的電壓或頻率的主要裝置叫變頻器，故該產(chǎn)品本身就被命名變頻器。
變頻不是到處可以省電，有不少場合用變頻并不肯定能省電。 作為電子電路，變頻器本身也要耗電（約額定功率的3-5%）。一臺1.5匹的空調(diào)自身耗電算下來也有20-30W,相當于一盞長明燈. 變頻器在工頻下運行，具有節(jié)電功能，是事實。但是他的前提條件是： 小李 15306977204（微信同號）
