CONSTANT MAGNET MANUFACTURING METHOD Russian patent published in 2011 - IPC H01F41/02 B22F3/87 

Abstract RU 2427050 C1

FIELD: electricity.

SUBSTANCE: cleaved surfaces of crystals of initial powder with more equal orientational mutual location of crystals in magnetic field are located as assembled together so that constant magnet manufacturing method is provided, which has extremely high orientation degree, which is the effect of invention. In the proposed method the initial powder (P) is loaded to cavity (22) and oriented in magnetic field by pressing or squeezing it with pressing device (5) in which pressing element (57) has the surface area which is less than section area of cavity. Subsequent change of position of pressing device throughout the section area of charging chamber provides mixing of initial powder with simultaneous orientation in direction of orientation in magnetic field. Thus, oriented semi-finished product is formed under pressure to the specified shape in magnetic field.

EFFECT: effect of invention is higher magnetic properties of constant magnet.
