Combined Method Reduction Calculation Time of 3D Transient Finite Element Analysis

摘要

This paper proposes a combined method to reduce 3D transient analysis time. The combined method is as follows. First, 3D static analysis is operated to get information of the magnetic field in the concern region. At this time, it is assumed that the magnetic field of the concern region is made from Permanent magnet or coil winding, and the magnetic field of the concern region is calculated except for armature coil in the concern region. The second, the distribution of armature coil current is modeled by using both 3D modeler and C program language.
