Fundamental

假設有一異向性磁性材料 a 在一個單一方向的磁場中,其d 軸與 q 軸有著不一樣的磁阻,磁場中的磁力線會趨向於較好通過的 d 軸。

當 d 軸與磁場的方向傾斜了角度 δ,磁力線被扭曲後, d 軸會傾向於 δ->0將磁力線拉直的方向的方向前進。

Introduction

同步磁阻馬達 (SynRM)分為 2 種,一種是同步磁阻馬達(SynRM),另一種是切換式磁阻馬達 (SRM)。

與一般凸極式同步電動機一樣,差別在轉子沒有永久磁鐵,完全靠 DQ軸磁阻差來產生轉矩,因此缺少激磁轉矩。

Control Strategy 恆角控制 :constant angle control(CAC)

最大轉矩控制 :maximum torque control(MTC)

最大功因控制 :maximum power factor control(MPFC)

最大轉矩變化率控制 :maximum rate of change of torque control (MRCTC)

感應軸電流恆定控制 :constant current in inductive axis current control(CCIAC)
