    摘要： The invention relates to a primary part (1) or secondary part (31) of an electric 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). To assure that a primary part (1) or secondary part (31) of this kind is comparatively simple to produce and assemble and has increased cooling performance or increased cooling efficiency compared to the prior art, it is proposed 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).
