Inductance_3D

Hello All

For calculating the inductance of the coils in 3D, what approach is more precise?

There are some topics for inductance calculation here but are a bit confusing. For example, the sensors could be used but solution output doesn't make sense. or ComputeInductanceMatrix macro is recommended but its missing in 3D. 

Any feedback is much appreciated.

MAny thanks and kind regards

Hello,

Usually to compute the inductance of a coil in 3D we used sensor of Flux on coil conductor components, and we display the Flux versus the current and we derivate the curve (dphi/di) to obtain the inductance. 

But indeed depending the application an the type of inductance you want to compute differents solution can be used. What kind of  device did you simulate in Flux: rotating machine, actuator, inductor for induction heating ?

Best regards.

Hello Cyril,
I want to compute the inductance of IPMSM motor in 3D.
I am not able to find computation of inductance matrix feature in altair 3d.
If we use sensor method to measure flux how to do frozen permeability ?
What should be the ideal way to compute inductance.

Your inputs on this question will be very helpful.

Siddhesh
