“…Nowadays finite element method (FEM) is an exact and popular technique, which is used through some commercial software for design and modeling of WRIMs and other electric machines 1 . However, FEM is a time‐consuming method, and it is better to be only used in the final stage for verifying the results 2 . Moreover, the user cannot obtain an in‐depth knowledge of the design and performance of electric machines while using the FEM software.…”

“…1 However, FEM is a timeconsuming method, and it is better to be only used in the final stage for verifying the results. 2 Moreover, the user cannot obtain an in-depth knowledge of the design and performance of electric machines while using the FEM software. To this end, hybrid analytical-FEM model has been presented in [3][4][5] for real time simulation, which previously prepares 3-D look-up tables for each element of inductance matrix through magneto-static analysis by FEM.…”

Accurate modeling of slotting and magnetic saturation effects has been two main challenges for analytical modeling of electric machines. In this article, first, different techniques such as sub-domain (S-D) model, winding function theory, magnetic equivalent circuit (MEC) model, and conformal mapping (CM) method are introduced to analytical model and analysis of electric machines. These techniques are also compared in terms of their accuracy, and computational complexity. Second, with respect to the comparison results, a new hybrid analytical model is presented for electromagnetic modeling of wound rotor induction motors, which consider the modeling accuracy of slotting and magnetic saturation effect, simultaneously. In this way, the air-gap region is modeled by using S-D model, and the iron parts are considered by using MEC model assisted by CMs. In final, the analytical results are verified by comparing with corresponding results obtained through finite element method and experiment set-up.
