“驅動電(dian)路"，以及(ji)逆變器和(he)電(dian)動機的“保護電(dian)路"組成。

(1)運算電(dian)路(lu)：將外部(bu)的速度，轉矩等指(zhi)令同檢測電(dian)路(lu)的電(dian)流，電(dian)壓信號進行運算比較，決定逆變(bian)器(qi)的輸(shu)出電(dian)壓，頻率。

(2)SEW變頻器(qi)電(dian)(dian)壓(ya)，電(dian)(dian)流(liu)檢測(ce)電(dian)(dian)路：與主電(dian)(dian)路電(dian)(dian)位(wei)隔離檢測(ce)電(dian)(dian)壓(ya)，電(dian)(dian)流(liu)等。

(3)SEW變(bian)頻器驅動電路(lu)：驅動主電路(lu)器件的(de)電路(lu)。它與(yu)控制電路(lu)隔離使(shi)主電路(lu)器件導(dao)通，關斷。

(4)SEW變頻(pin)器(qi)速(su)度檢(jian)測電路以(yi)裝在異步(bu)電動機軸機上的(de)速(su)度檢(jian)測器(qi)的(de)信號為速(su)度信號，送入運算回路，根(gen)據指令(ling)和運算可使電動機按指令(ling)速(su)度運轉。

(5)SEW變(bian)頻(pin)器(qi)(qi)保護(hu)電(dian)路(lu)(lu)：檢(jian)測主(zhu)電(dian)路(lu)(lu)的(de)電(dian)壓，電(dian)流等，當發生(sheng)過(guo)(guo)載(zai)或者過(guo)(guo)電(dian)壓等異常時，為了防止(zhi)逆變(bian)器(qi)(qi)和異步電(dian)動機損壞，使(shi)逆變(bian)器(qi)(qi)停止(zhi)工作或抑制電(dian)壓，電(dian)流值。

     SEW變(bian)(bian)頻器(qi)(qi)變(bian)(bian)頻器(qi)(qi)功率范(fan)圍達到 160KW ，適用于幾(ji)乎所有的開環驅動應用，可對 SEW變(bian)(bian)頻器(qi)(qi) 和(he)非 SEW 交流減速(su)(su)電機進行變(bian)(bian)頻調(diao)速(su)(su)。

操(cao)作操(cao)作及顯示完備的功(gong)能、簡(jian)便的操(cao)作，出廠值(zhi)適用(yong)于大多數(shu)應用(yong)場合。可通過紅外接(jie)口(kou)進行快速、準確(que)的參(can)數(shu)設定(ding)及操(cao)作。

    德國(guo)SEW電(dian)(dian)(dian)(dian)機(ji)不僅可(ke)以降低電(dian)(dian)(dian)(dian)阻損(sun)耗，而且可(ke)以地提(ti)高(gao)功率因數。例(li)如，永磁同步電(dian)(dian)(dian)(dian)機(ji)可(ke)以在25%～120%的額(e)定(ding)負(fu)載范圍內(nei)保(bao)持較高(gao)的效率和(he)功率因數。16以內(nei)的微(wei)型永磁直流電(dian)(dian)(dian)(dian)動機(ji)的效率比同規格的電(dian)(dian)(dian)(dian)勵(li)磁電(dian)(dian)(dian)(dian)動機(ji)提(ti)高(gao)10%～20%。將(jiang)風機(ji)、泵負(fu)載電(dian)(dian)(dian)(dian)機(ji)改為永磁電(dian)(dian)(dian)(dian)機(ji)后，綜合節能效果十分顯(xian)著(zhu)。功率越(yue)大(da)，勵(li)磁損(sun)耗占總損(sun)耗的比例(li)越(yue)大(da)，永磁電(dian)(dian)(dian)(dian)機(ji)效率高(gao)的就越(yue)突出。
