POWDER-BASED SOFT-MAGNETIC INDUCTIVE ELEMENT AND DEVICE FOR ITS PRODUCTION Russian patent published in 2013 - IPC B29C70/32 H01F1/28 B29C41/04 

Abstract RU 2492050 C2

FIELD: process engineering.

SUBSTANCE: invention relates to production of soft-magnetic composites. Proposed method comprises making of spun casting mould with, at least, one casting cavity, connected with rotary drive shaft. Then, inductor is arranged in said mould and said cavity is filled with binder and said-magnetic metal powder. Said shaft is revolved to rotate said mould for compaction of said soft-magnetic metal powder by centrifugal forces toward one side of aforesaid cavity. Note here that shift with binder occurs to form the element including soft-magnetic composite.

EFFECT: lower losses in switching.
