Inductor With An Air Gap Calculation Yelds Dubious Results

In the case of a transformer or inductor the air gap only reduces the slope of the bh loop reducing permeability and inductance and hence increasing the magnetizing current in the primary.

Inductance of inductor with air gap. Gapped core inductance calculator. It has nothing to do with energy storage its just matter of building inductuctors for specific inductancecurrent. The core is from a standard tv.

The value expressed above is approximate and neglects fringing flux and other nonidealities. The inductance of an iron core inductor carrying direct current and having an air gap may be expressed as. This online calculator allows you to calculate the air core inductance in any applications.

1 measurements of inductor properties vs. Inductor design14 determine air gap length with ac expressed in cm2. Hence if the applied voltage were to be increased to the point of saturation introducing an air gap wouldnt help.

The air gap length is given in meters. L g u 0 li max 2 b max 2 a c 104 m. U 0 4 107 hm.

Gapped cores were used in low power transformers to control the inductance and increase the quality factor q of air core inductors. Mpl henrys 8 9 this equation shows that inductance is dependent on the effective length of the magnetic path which is the sum of the air gap length lg and the ratio of the core mean length to the material permeability mplum.
