Elien,
It is also worth noting -
In your circuit, where you have a resistor in series with your inductors L1-LM and L2-LM, you can move the resistors into the inductors by setting Rser = 1.3 ohms on each of those two inductors.? And set LM's Rser to 0.? You don't have to do that, but it can make the simulation run a little faster, and perhaps slightly more accurately than having a separate inductor and resistor in series.
On the other hand, you might want to keep the inductance and the resistance separate on the schematic, especially if the schematic will be published for others to see.
Regarding Jerry Lee Marcel's note about simulating coupled inductors using the TEE (or T) equivalent circuit, I agree, but some people just need to do it the other way.? Some schools teach the TEE equivalent as if it is the way to analyze coupled inductors, without recognizing the fact that SPICE does not need to do that.? To each his/her own.
