Abstract

A device in a stator of a rotating electric machine comprises a compressing ring (2) at each end of a stator core (5) with a plurality of axially arranged and joined-together layers of a magnetic material (5a), arranged one after the other, between which layers there is arranged a layer of electrically insulating material (5b). Channels (10) are arranged in the compressing rings (2) for passage by a coolant. The channels (10) are essentially radially arranged in the compressing ring. The channels comprise voids which may be limited by two adjacently located layers of magnetic (5a) and/or electrically insulating (5b) material as well as two elongated spacers (11a, 11b) essentially radially arranged between the two layers.
