Ansys maxwell 3d material library

In summary: Reduce the vertical force by using the damping factor. In the Materials Editor, go to the Damping tab and set the Damping Factor to 1.5. This will reduce the vertical force to about 2000 N.

hi everybody. i just wonder. can we add new material library in ansys maxwell 3d(v.16) manually. especially magnets?

Yes, of course, go to Tools -> Edit Configured Libraries -> Materials -> Add Material and then from the dropdown menu (Calculate Properties) choose Permanent Magnet.

but i don't know properties of N50 magnet. İ just found Br value. i need Mu and Hc values too. where can i find ?

OK

Mu is relative permeability. Mo*Mu is Slope of BH curve. If you guessed the curve of PM in the second quadrant linear, equation is

Mu*Mo=Br/Hc
Mo=4*pi*10^(-7)

For N50 is
Br=1.425
Hc=971 000

And Mu is: 1.167846519

If you want to enter the non-linear characteristic, then you must enter the point by point. In Maxwell Help, you have instructions for how to do it.

thank you so much :)

i just tried. add new material -> calculate for permanent magnet

new windows comes up and i entered Mu and Hc values in their spaces and Br values calculated automaticly 1,425 .
i click ok button. so new material is added. but i got a warning message. the message is:

" Material 'n50_deneme': The magnitude of Magnetic Coercivity is expected to be <= 0. If you use a positive value the direction used will be the opposite of the unit vector specified. (12:54:09 Eki 30, 2013) "

still i do my analysis. and the force i calculated is bigger than NdFe35. it seems it work :)

but i wonder about the warning. is it important ?
 
  • #11
For Magnetic Coercivity you must put negative value: Hc=-971 000 A/m
 
  • #12
ok. i will try negative value. thank you for your help
 
  • #13
i change Hc value to negative and now it seems ok. thank you so much. may i ask what are you doing with maxwell?
 
  • #14
Of course
 
  • #15
I am doing design of electric machines
 
  • #16
i am so new at maxwell . only two moths. so my question is really simple :) i want to do a linear motor simulation. and i am studying on

SEW-EURODRİVE

typ: SL2-P050S-010

motor. but my desing is not even close with it :S
do you have some advice for me?
 
  • #17
Advice? :-) If you have any problems, you can ask me. If I knew, I'll help you
 
  • #18
ok than if i send you my project, design could you take a look? and have some problems too. so i can ask them.
 
  • #19
of course
