所謂“直流制動”，一般指當變頻器的輸出頻率接近為零，電機的轉速降低到一定數值時，變頻器改向異步電動機定子繞組中通入直流，形成靜止磁場，此時電動機處于能耗制動狀態，轉動著的轉子切割該靜止磁場而產生制動轉矩，使電動機迅速停止。

在電動機制動過程中，由于變頻器輸出頻率逐漸降低，則定子繞組內的同步磁場轉速低于轉子轉速，電動機處于再生制動過程，此時旋轉系統存儲的動能轉換成電能熱損耗的形式消耗于異步電動機的轉子回路中，為防止電動機減速過程中所形成的再生發電制動以及直流制動過程中的能量回饋，造成變頻器和電機的損壞，需串入專用制動單元／制動電阻。在通常電動機的制動過程中，電動機先減速，電動機同步旋轉磁場轉速低于轉子轉速，工作點在同一轉速下由A點跳至B點，即從第一象限過渡到第二象限稱之為同一轉速下特性的跳轉，則電機得到反方向的制動轉矩T進入發電制動狀態，拖動系統迅速降速，當低于某一轉速后，向定子繞組輸入直流，形成固定磁場，產生制動轉矩。在這一過程中，電機將經過再生發電制動和能耗制動而最終停止。 A6X30013318
