This thesis focuses on the effects of mechanical punching process on magnetic properties of electrical steels and on electrical machine performance. The scalar Sablik model with some improvements has been considered to account for the degraded magnetic properties. It allows to describe both magneto-elastic and magneto-plastic coupling. The identification process is carried out using measured magnetization curves under different elastic stresses and plastic strains. Since the model accounts directly for the plastic strain, a mechanical punching process simulation has been performed using the software ABAQUS.A finite element simulation of a synchronous machine including the effect of punching process shown the degradation of the magnetic flu...
