Abstract (en)
[origin: EP1655747A2] The lamination has a sheet metal component forming a yoke (34), external blades and a middle blade (30) of a section of a core. Another sheet metal component forms another yoke (32), where ends of the blades impinge against a longitudinal side of the yokes in a composite condition of the components, such that two windows are formed. A recess is provided in a portion of each window and via which a surface of the windows is increased.
