Abstract

The equivalent fixed grid and moving grid models for the finite element (FE) analysis of an induction machine are presented. The discussed transformation is the FE representation of the classical commutator transformation. The obtained fixed grid model takes into account the higher space harmonics of the flux density wave and can be used in the FE analysis of the machines with solid rotor, drug‐cap rotor, and squirrel cage winding. The models have been applied in the calculations of TEAM Workshop problem No. 30. The test problem has been solved analytically. The FE results and analytical results are very close.
