Influence of rotor position on oversaturated areas size of induction machine magnetic circuit

This article contains a solution of magnetic field distribution with oversaturated areas localization and description. The rotor position is important for the maximal magnetic circuit saturated identification and oversaturated areas size influence of magnetic circuit due to the variable magnetic reluctance of path. Influence of rotor position on saturated magnetic circuit is analyzed with step on twenty angular positions per rotor slot pitch. This analysis is done for 3-phase 1.1 kW induction machine by finite element method. This the time behavior of magnetic flux density is analyzed in air gap for different load conditions of machine. The paper contains also general postprocessor results juxtaposition.
