變頻器制動電阻的選擇 在變頻調速系統中，電機的降速和停機是通過逐漸減小頻率來實現的，在頻率減小的瞬間，電機的同步轉速隨之下降，而由于機械慣性的原因，電機的轉子轉速未變。當同步轉速小于轉子轉速時，轉子電流的相位幾乎改變了180度，電機從電動狀態變為發電狀態;與此同時，電機軸上的轉矩變成了制動轉矩，使電機的轉速迅速下降，電機處于再生制動狀態。電機再生的電能經續流二極管全波整流后反饋到直流電路。由于直流電路的電能無法通過整流橋回饋到電網，僅靠變頻器本身的電容吸收，雖然其他部分能消耗電能，但電容仍有短時間的電荷堆積，形成“泵升電壓”，使直流電壓升高。過高的直流電壓將使各部分器件受到損害。因此，對于負載處于發電制動狀態中必須采取必需的措施處理這部分再生能量。處理再生能量的方法：能耗制動和回饋制動. 能耗制動的工作方式 能耗制動采用的方法是在變頻器直流側加放電電阻單元組件，將再生電能消耗在功率電阻上來實現制動。這是一種處理再生能量的直接的辦法，它是將再生能量通過專門的能耗制動電路消耗在電阻上，轉化為熱能，因此又被稱為“電阻制動”，它包括制動單元和制動電阻二部分。
