[Getdp] PMSM Torque Calculation

[Julien Dolo]

Hi everyone,

I've been using getdp & gmsh for almost 2 months now. I'm trying to model a
PMSM with surface-mounted magnets. So far I managed to get both linear &
non-linear formulations working, and I'm able to calculate inductances &
bemf.

Right now I'm trying to successfully calculate the electromagnetic torque
produced by the motor. I've taken a look at all the examples I could find
online, and tried to use the virtual works principle & the maxwell stress
tensor methods, with no real success. What I'm trying to do with that model
is to apply a current on the q-axis and calculate electromagnetic variables
versus the rotor angle (I'm running several static resolutions with the
Onelab loop feature).

I've attached all the files needed to run my model (except empty.pro which
is just an empty file to bypass a bug - the MagSta.pro file was
systematically loaded twice, causing an error).

I'm a student in an engineering school and not quite gratuated yet, so my
files are probably far from perfect - any advice that could improve my
model would be greatly appreciated !

Thanks in advance to those who'll take the time to look at my work (if
anyone does)

Best regards everyone,
