Hey Group, I’m having some trouble getting valid force numbers for my axisymmetric pot
core solenoid model. I’m not able
to define a contour in the very tight air-gaps surrounding the armature. I’ve opted to estimate force using F=(A*B^2)/(2*mu) Where A = Armature
Area, B=Average Flux Density along Armature Face, mu = permeability of air. My question: Because (B.n.average)^2 doesn’t equal (B.n^2)average. Which
should I use? Why? Is this method going to yield accurate
results? Also: is there anywayto
show an H density plot around the circuit? I can define a contour around the magnetic circuit then plot
H, but this doesn’t give me a feel for the ‘high MMF drop’ regions as well as
an H-density plot would. Any
suggestions? Thanks, Jay D. Greener |
