MAGNET SYSTEM AND METHOD FOR MANUFACTURING PERMANENT MAGNETS AND MAGNET SYSTEMS (VARIANTS) Russian patent published in 2022 - IPC H01F1/53 H01F1/57 H01F7/02 B22F3/105 B82B3/00 

Abstract RU 2773894 C1

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely, to a method for manufacturing magnet systems with locally variable texture, and can be used for producing permanent magnets, magnet systems and apparatus based thereon through methods of additive technology (3D printing). The result is achieved due to the use of a mixture of powders, wherein one (A) is nanocrystalline textured hard-magnetic, based on an alloy of a Nd-Fe-B system, the other (B) is a two- or multicomponent alloy based on R-Cu, wherein in order to manufacture a magnet on a substrate, the mixture is applied to the substrate, the layer of powder is heated locally by a laser beam or an electron beam in an inert atmosphere or in vacuum until powder B melts and powder A undergoes liquid-phase sintering. In implementation of the method by means of jet application of the binder, powder A is applied to the substrate, the binder is locally applied to the surface of the layer of powder in order to mutually adhere the particles of powder A. After the article is manufactured, the procedures for removing the binder and infiltrating the manufactured product with alloy B are performed. The magnet or magnet system produced by means of the claimed methods constitutes a single integral element based on the above mixture. The magnet or magnet system therein comprises a first area with a first distribution of the easy magnetisation axes therein, and subsequent area, each with a distribution of the easy magnetisation axes different or similar to at least one first area.

EFFECT: increase in the magnetisation control at each point of the sample.
