This Multi-gap Toroidal Core Design Tool simplifies complex magnetic component engineering directly in your web browser. By entering the ideal core dimensions, gap conditions, and materials, the platform instantly calculates precise core factors, magnetic properties, and essential physical parameters. This automated process eliminates manual calculations to accelerate your magnetic design workflow.
Input the core dimensions:
OD (mm)
ID (mm)
HT (mm)
Input the spacer gap conditions:
1. The number of spacer gaps:
The number needs to be ≥ 2 and the arc angle between two adjacent gaps equals 360° divided by the number.
2. The spacer thickness (mm):
Select the material grade:
Output the results:
Core factors:
C1 = mm⁻¹
C2 = mm⁻³
Effective core parameters:
Ae = mm²
Le = mm
Ve = mm³
Magnetic properties:
μe =
AL = nH/N²
