ANALYSIS OF PERMANENT-MAGNET LIFTING DEVICES USING FINITE-ELEMENTS

This paper describes an analysis process for a novel rare-earth perman ent magnet lifting device by using finite element analysis. In the pas t ferrite and alnico magnets have been used in permanent magnet liftin g devices which are extremely cheap compared to the neodymium-iron-bor on magnets. Therefore optimized systems are not designed due to additi onal costs involved in purchasing and carrying out finite element anal ysis. Furthermore trial and error solutions have been associated with such designs for a long time, but now finite element analysis can not only enhance the design of the system but also predict whether the nem design mill function according to specifications.
