I'm doing a simulation on Ansys Maxwell of a spiral inductor. You can see the picture of the real inductor and its measured value with an RLCmeter is ~108µH.March 22, 2022 at 9:25 amNavya CAnsys Employee
Check if the way you connected the coils in Maxwell is creating an opposing effect instead of aiding.
First, simulate a single coil and check the inductance value. This will confirm the above check point.

Connect both the coils such that the current in both will in the same direction.
March 25, 2022 at 7:37 amMalnyrSubscriberMarch 25, 2022 at 10:14 amMarch 25, 2022 at 2:28 pmMalnyrSubscriberHi again, now I did this :
One entry and one output for each coil. And I measured the two self inductance and the mutual inductance :
Where we find again the inductance value for a single coil. Then to know the value of the whole, we need to apply the formula : Ltotal = L1+L2+2*Lmutual = 26.73+28.95+2*25.55 = 106.78┬ÁH which is exactly the measured value ! So I guess it's not possible to get the real inductance value directly because I tried in the previous message. Thank you for you help, I think I now undertand how it works !
March 25, 2022 at 4:04 pmNavya CAnsys EmployeeYes, If you excited them as two coils. L(Current1, Current1) and L(Current2, Current2) are self inductances and L(current1, current2) is the mutual inductance
Glad that you got the correct result.

Interesting work you did. what solution type did you use to compute the inductance?
I am also trying to calculate the inducutance value at certain frequency but I am lost in setups.
No idea how to set frequency as you did. a bit of help would be great
thank you!Viewing 9 reply threads
