System for manufacturing permanent magnets generating magnetic fields, and relevant elementary or composite permanent magnets.

摘要

The system according to the invention to manufacture magnetic field generators includes substantially the steps of: 1) Marking of at least one conventional tile made of known magnetic material, setting an identification code recognizable during the following steps. 2) Cutting of each tile, identified as explained, in n strips having two dimensions and the orientation of the A-A axis equal to those of the initial tile (Pc). 3) 90 DEG rotation around an axis perpendicular to the described A-A axis, in order to obtain the rotated strips STr having orientation A-Ar. 4) Selection and re-arrangement of the rotated strips in order to obtain (after step 5) the desired characteristics of simmetry and compensation of the magnetic characteristics variations of the m tiles input of the process. 5) Assembling (e.g. by glueing) of the strips STr, rotated as explained, to form a new tile Pr with orientation A-Ar sub 3. 6) Cutting of the assembled tiles in w slices (e.g. triangular) SPi. 7) Magnetization of the w slices (e.g. triangular) SPi. 8) Assembling of a set of slices (e.g. triangular) SPi in magnet forming elements (EFM). 9) Tuning of the described EFM elements. 10) Assembling of the elements EFM to obtain magnets. 11) Tuning of the finished magnets (MF).
