Abstract (en)

[origin: WO0135427A1] The aim of the invention is to produce multipole magnetic systems which are composed of several individual magnetic components that preferably consist of rare-earth magnetic material. The invention relates to a method for producing and magazining at least one individual magnetic component, a magazine (40) for at least one individual magnetic component (1, 2) by moulding and for conventionally magnetising the same. The invention also relates to a method of assembly for producing a magnetic system and to the resulting magnetic systems. According to the invention, extremely flat multipole magnetic systems, in the form of magnet rings (1, 2) or magnet strips for instance, can be produced by means of individual magnetic components which are directly adjacent to each other or are arranged at a distance by means of a moulding material, and three-dimensional magnet bodies, such as a magnetic scale for instance. The inventive magnetic systems are provided with a particularly high integration level of the individual magnetic components and a homogenous entire magnetisation of the magnet segments which, acting as permanent magnet components, can be used in electromagnetic drives, magnetic path and angle measuring systems, magnetic couplings and valves for instance.
