  • 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
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)
