The process of manufacturing iron cores for electric machines out of electrical steel can drastically influence the magnetic properties of the material. It is well known that the local soft magnetic properties are degraded by the cutting process. In the production process the material also experiences tensile and compressive stress, i.e. when pressing the(More)
The punching of electrical steel sheets to manufacture iron cores for electrical machines can influence drastically the final magnetic properties of stator and rotor cores. In this paper, the influence of punching on the magnetic properties is studied on 5 mm wide ring core samples. Six different fully processed non-oriented electrical steels with varying(More)
