2 Finite Element Model

The machine chosen for this study is a wound rotor synchronous machine where the nominal dimensions are presented in Table 1.Table 1Nominal dimensions of the stator

Stator inner diameter

54 mm

Stator outer radii

100 mm

Stator middle radii

71 mm

Stator teeth width

5.5 mm

Stator slot height

17 mm

First, a finite element model of the stator is created used ANSYS-APDL. This model is then subjected to a mesh convergence study.

2.1 FEM Creation

ANSYS APDL is the finite element software chosen to work on due to its flexibility during work. A FEM model can be created using a code text file in APDL. This feature is very important since variability or simply sensitivity study is targeted. All results are saved automatically for each simulation in a separated text file. This FEM model presented in Fig. 1 is suitable for a sensitivity study of any geometrical or material parameters. Actually, the dimensions and the material properties are modeled as variables in the code text file.
