... anisotropic magnetostatic field computation. The 3D magnetic field in a reactor, the inductance and the voltage‐current characteristic (V‐I curve) of the reactor are calculated. The harmonic components under 1.35 times rated voltage are analyzed by the calculated V‐I curve. The calculated results are quite...

...T.S. Low; C. Bi; Z.J. Liu In electric machines, the electromagnetic torques and forces are developed as a result of the interaction of the magnetic fields. These forces can be computed from the results of field analysis, using numerical or analytical methods. Describes a hybrid technique, which...
