Magnetic changes at the sheet edges are insignificantly small in the case of transformers. In the electric machines they can produce significant losses, amounting to 0.5 % when the losses due to the magneto-elastic and reverse phenomena (Joule and Villari) are taken into account. In this context the paper presents the results of laboratory and simulation studies of the influence of various production technologies on the material structure and magnetic properties at edges of elements for electro-mechanical devices. Keywords:magneto-elastic and elasto-magnetic effects, plastic strains, changes of magnetic parameters, changes of magnetic hysteresis loop of electromagnetic steel sheet Affiliations:| Żurek Z.H. | - | Silesian University of Technology (PL) | | Kurzydłowski K.J. | - | Warsaw University of Technology (PL) | | Kukla D. | - | IPPT PAN | | Baron D. | - | TurboCare Poland S.A.
