Modeling of Three Dimensional Magnetic Field in Three-Phase Induction Motor with Double Squirrel Cage

From three-phase induction machines, asynchronous double-cage rotor motors stand out as more specific, as in the construction and after the performance. Such a type of motor is selected as the objective of a study, and in this paper will be shown a part. Namely, the model will be given three-phase asynchronous motor with double cage rotor over which will be made electromagnetic analysis, software that performs calculations using the well-known powerful finite elements method in the 3D domain. Three dimensional magnetic fields and the distribution of the flux density at the middle line of the air gap of machine will be presented as a result of this analysis.
