1、永磁同步電機的電壓U、電流I、功率因數(shù)角δ已知，則
1）直軸電流 Isinδ
2）交軸電流 Icosδ
3）阻抗 Z=U/I
4）感抗 X=Zsinδ
5）阻抗 R=Zcosδ
2、從永磁同步機的參數(shù)看：
1）直軸電流 Io-Emcosδ/N1
2）交軸電流 Emsinδ/N1
3）主旋轉磁勢IoN1=BS×L/Sμ
4）磁路磁阻Rm=L/Sμ
5）主旋轉磁通Φo=BS
3、從電流的性質看：
1）直軸電流為勵磁電流與無功電流的和
2）交軸電流為有功損耗與轉矩電流的和
4、所以永磁同步電機只有直軸電感，沒有交軸電感；
5、直軸電感L
1）感抗X=2πfL
2）L=X/2πf
