Electromagnetic device's e.g. electromagnetic brake, efficiency optimizing method, involves filling out parasitic areas in region of body and wire wound coil of electromagnetic device by conductive materials, and embedding areas into matrix

摘要

The method involves filling out parasitic areas (2) completely or partly in a region of a magnet body (1) and a wire wound coil e.g. field coil (3), of an electromagnetic device by magnetically conductive materials. The areas are embedded into a matrix from the materials that contain iron in a firm form, where the materials are selected form a group consisting of iron powder, iron chips, magnetorheological liquid, ferrous fluid or conductive paste, which is selected from two-component epoxide resins, two-component silicone resins, and two-component resins on basis by natural synthetic resins.
