Channels for three phase rotating electrical machines with two cooling circuits, in a sheet metal package (1), have fluid flowing close to the outside periphery and gas channels (2, 3). The gas channels are grooves. Fluid flow channels are connected by short circuit arcs in the pressing frame on one side of the machine, and vertically stacked bridging arcs on the other side. The fluid inlet and outlet have recesses at the gas flow channels. An Independent claim is also given for a method of forming the above arrangement.
