Abstract

A linear motor stator arrangement including a coil arrangement with conductive electrical coils arranged along an axis for generating a magnetic field, a convective cooling device with a fluid line extending along a pathway, a section of the fluid line exhibits as a cooling section outlet ports in a fluid line wall which faces the coil arrangement and are arranged along the pathway with a spacing therebetween, the stator arrangement having a conveyor device which is connected with the fluid line and for conveying a fluid in the fluid line and through the outlet ports to the coil arrangement, wherein 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 in different regions of the cooling section along the pathway are quantitatively different.
