Abstract:
1. A primary part ( 1 ) or secondary part ( 31 ) of a linear motor ( 2 ), having a core ( 3 ) of a magnetically conductive material, which forms slots ( 4 ) for the windings ( 5 ), and at least one cooling tube ( 6 ), through which a coolant fluid ( 7 ) can flow, is inserted into the slots ( 4 ) under the windings ( 5 ), characterized in that the effective slot cross section has an at least local retaining constriction ( 10 , 11 ) relative to the cooling tube ( 6 ), so that the cooling tube is fixed by the retaining constriction ( 10 , 11 ) in its seat in a receptacle region ( 12 ): of the slot ( 4 ), and the slot cross section in the receptacle region ( 12 ) has a contour ( 13 ) corresponding to the outer contour ( 14 ) of the cooling tube ( 6 ) in such a way that the cooling tube ( 6 ) has a surface contact ( 18 ), extending substantially over its length, with the inner wall ( 19 ) of the receptacle region ( 12 :, the surface contact being at least local with respect to its outer circumference ( 17 ), wherein the cooling tube ( 6 ) has a flattened level shape on a top face ( 24 ) for supporting ( 26 ) the windings ( 5 ) located above the cooling tube ( 6 ).
