PROCESS OF APPLICATION OF WINDING ON ELECTROMAGNETIC ELEMENT Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: process of application of winding on electromagnetic element consists in laying of band conductor in the form of square into multiwindow magnetic core with parallel rectangular legs and in successive embracing of legs of magnetic core by turns of winding. Legs of magnetic core are produced from magnetically soft material. Band conductor of winding is applied perpendicular on to first leg of magnetic core. On other side of band conductor next leg of magnetic core is applied around which flat conductor of winding is bent. Then succession of specified actions is repeated up to manufacture of stack of required thickness from winding and magnetic core which are then tied up and fixed. Usage of materials of winding and magnetic core reduces by not less than 15% , heat removal improves by not less than 25% , design strength of winding increases by not less than 50% and reduction in mass and dimensions amounts to 20% . In compliance with another approach to process of application of winding on electromagnetic element magnetic core is made from magnetically soft material. Band conductor of winding is applied perpendicular on to strip of magnetic core. Winding is accomplished by successive bending by 100 deg of strips of magnetic core and of bands of conductor with reference to each other. Succession of specified actions is repeated up to manufacture of stack of magnetic core and winding of required thickness which is then pulled together and fixed. In third approach band conductor of winding is embraced over all sides with strip magnetically soft material. Produced combined band is shaped in accordance with required profile and is fixed. EFFECT: reduced usage of materials, diminished dimensions and mass, increased heat removal and strength of winding. 3 cl, 10 dwg
