ABSTRACT:
The object of the invention is to produce multipole magnetic systems that are composed of a plurality of individual magnetic components that preferably are made of rare-earth magnetic material. The invention relates to a method for producing and magazining at least one individual magnetic component, a magazine for at least one individual magnetic component by molding and for conventionally magnetizing the same. The invention further relates to a method of assembly for producing a magnetic system and to the resulting magnetic systems. The invention teaches that extremely flat multipole magnetic systems in the form of magnet rings or magnet strips and three-dimensional magnet bodies such as a magnetic scale, for example, can be produced by means of individual magnetic components that are directly adjacent to each other or are arranged at a distance by means of a molding material, for example. The magnetic systems taught by the invention are provided with a particularly high level of integration of the individual magnetic components and a uniform overall magnetization 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 example.
