LLC AmpereMagnete (AMT&C group of companies) received a decision under the international patent cooperation system (PCT) for the patent “Method of manufacturing segmented permanent magnets from substandard magnetically hard sintered raw materials.”

A method for processing substandard magnetically hard sintered raw materials for the production of segmented permanent magnets (SPM) includes primary sorting of raw material samples into groups according to geometric characteristics and appearance, taking into account the required SPM parameters, selective measurement of magnetic, chemical and microstructural parameters and conducting a HAST test to determine the fundamental possibility of manufacturing SPM, as well as the production of a pilot batch of SPM, including cutting samples into parts of a given configuration, gluing the parts into a multilayer package, cutting and grinding the surface of the resulting multilayer package to a given size and applying a protective coating to the surface of the resulting SPM.
