无线充电绕线线圈电感计算器

      

Formula used in this calculation is based on the Harold A. Wheeler approximations.

...where:

Di =inner diameter in inches.

s =distance between windings in inches.

w =wire diameter in inches.

N = number of turns.

Do =outer diameter.

1 inch = 0,0254m=2,54cm = 25,4mm.

This formula applies at 'low' frequencies (<30MHz) ) using enameled copper wire. Some people call it "magnet wire".
