Linear motor stator arrangement with external convective forced cooling

Abstract

A linear motor stator arrangement comprising a coil arrangement with a plurality of conductive electrical coils arranged following one another along a sequence axis for generating a temporally and spatially varying magnetic field in the neighborhood of the coil arrangement, and further comprising a convective cooling device which exhibits 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 exhibits as a cooling section a large number of outlet ports in a fluid line wall which face towards the coil arrangement and are arranged one after another along the pathway at a spacing from one another, where the stator arrangement further comprises a conveyor device which is connected with the fluid line and is configured 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 in different regions of the cooling section along the pathway are quantitatively different.
