Abstract
Almost all electrical machine consists of the stator and rotor cores, which are made of stacked non-oriented electric steel sheets. Punching and blanking are the two commonly used shear cutting technologies. The efficiency and performance of an electrical machine depend on the magnetic properties of its magnetic core. The shear cutting process causes the formation of residual stresses in cut segments next to the cutting line from the non-oriented electrical sheet metal, resulting in increased iron losses. The extent of deterioration in the magnetic material properties depends on the amount of induced stresses, which is affected by the used process parameters during shear cutting and the mechanical properties of the electrical steel sheets. This paper focuses on the residual stresses induced by punching with different shear cutting conditions using finite element analysis. Influence of cutting clearance of the shear cutting tool on were observed.
