1. A Linear motor stator arrangement capable of convective forced cooling, comprising a coil arrangement with a plurality of conductive electrical coils arranged one after another along a sequence axis for generating a temporally and spatially varying magnetic field in a neighborhood of the coil arrangement, and further comprising a convective cooling device exhibiting a fluid line extending along a pathway, of which at least one section runs alongside the coil arrangement at a spacing from it, where a section of the fluid line running alongside the coil arrangement as a cooling section exhibits in a fluid line wall a large number of outlet ports which face towards the coil arrangement and are arranged one after another at a spacing from one another along the pathway, where the stator arrangement further comprises a conveyor device which is configured so as to be connected with the fluid line and for conveying a fluid in the fluid line and through the outlet ports to the coil arrangement, where in the cooling section there are provided along the pathway outlet ports with quantitatively different outlet port cross-sections through which fluid can flow and/or the spacings between two outlet ports arranged immediately one after another along the pathway are quantitatively different along the pathway in different regions of the cooling section.
