Abstract 本文提供一個新的反電動勢檢測技術，可以廣範圍的控制。 特點: 1.解決以前只能控制high or low duty的情況。 2.不需要使用任何hall or position sensor=用未激磁相量測到 的端電壓來計算反電動勢的零交越點，產生正確的換相控制。 3.容易使用數位系統來實現=使用FPGA架構來實現BLDC Driver System。

Introduction 與感應馬達比較，優點：沒有轉子側的銅損。 減少BLDC控制成本的做法=無感測器控制。 這些參考論文使用的方式都使用從量測與dc-link串聯 的 “電阻”產生的資料，重建中性點電壓和終端點電壓。 各參考論文提及:
