Abstract (en)
[origin: WO2016008727A1] The invention relates to a core (1) for an electrical induction device, comprising a plurality of lamination stacks (2) which are each formed by laminated sheets (11, 11.1, 11.2), wherein the lamination stacks (2) lie on top of each other parallel to the layer plane of the laminated sheets (11, 11.1, 11.2). According to the invention, at least one of the lamination stacks (2) is segmented and has at least two partial lamination stacks (3), the two partial lamination stacks (3) respectively lying opposite each other with their stack end faces (3a) standing transverse, in particular perpendicular, to the layer plane of the laminated sheets (11, 11.1, 11.2), the stack end faces (3a) of the two partial lamination stacks (3) have a spacing between each other through which a gap is formed extending between the two partial lamination stacks (3) perpendicular to the layer plane, and the gap forms a cooling channel (4) or at least a section of a cooling channel (4), the channel longitudinal extension thereof extending transversely, in particular, perpendicular to the layer plane of the laminated sheets (11, 11.1, 11.2).
