Coil and transformer core

The! Firing relates to a coil and transformer core of _s composed of at least two out of a ferromagnetic material, in particular of a ferromagnetic material of high permeability and / or consisting of a magnetic material sand core parts and is provided with air-gap "

In electrical communications and measurement technology: steps Frequently the demand for such coil and transformer cores to be provided with means that enable the magnetic resistance to be adjusted «

According to the firing, this is achieved in that the core parts forming the inner core are surrounded by a closed outer band core, and that between the inner core and the outer one

EE-I cores the required air gap or the shear caused thereby can also be distributed over three legs, whereby the core production is considerably facilitated.

Is it particularly beneficial _? Make the adjustment parts U- or ring-shaped, since this completely shields the stray force lines that arise at the air gap. This shape also enables better mechanical milling and fixing of the adjustment parts. . . ■ "· ■"'"'." . '"■■". ., ::
