A fast semi-analytical model for the slotted structure of induction motors with 36/28 stator/rotor slot combination

A fast, semi-analyticalmodel for inductionmotors (IMs) with 36/28 stator/rotor slot combination is presented. In comparison to traditional analytical models for IMs, such as lumped parameter, magnetic equivalent circuit and anisotropic layer models, the presented model calculates a continuous distribution of the magnetic flux density in the air gap and both the stator and rotor slots of the IM. Due to its semi-analytical nature, the computation time of the model is short in comparison to Finite Element Analysis (FEA) simulations. Also, it is shown that the model results are in good agreement with linear FEA simulation results. This makes the model very suitable for design tools
