Optimization of the Electromagnetic Characteristics of a 3-Phase Squirrel-Cage Induction Motor Using FEM (original) (raw)

The induction motor due to its characteristics forms the most common choice of industrial applications worldwide. In this work, with the use of FEM analysis, a specific induction motor is optimized under three different criteria. The geometric features of the rotor compose the designing variables of the optimization process. Three models have been created and studied. These resulting models present optimized electromagnetic characteristics depending on the designer’s restrictions and also on the application requirements. The finite element analysis carried out is AC steady-state and takes into consideration the non-linear characteristic of the stator and rotor iron core.
