A 3-D Calculation of Electromagnetic Field in a Multiphase Induction Motor

Abstract:

Three-dimensional finite element analysis of harmonic electromagnetic field in a large and complex structure 15-phase induction machine has been completed. Accurate 3D finite element machine model is established. The current density of stator and rotor and the entire vector flux density distribution are given, then been analyzed and explained. 3D air gap radial flux density is obtained and has been made harmonic analysis. We can get more accurate electromagnetic field distribution and performance parameters through 3D finite element calculation of electromagnetic field. This method can give theoretical basis for the multiphase machine development of new structure and can play reference in terms of structural optimization design.
