Ansys maxwell 3d material library

  1. Oct 21, 2013 #1
    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 dont know properties of N50 magnet. İ just found Br value. i need Mu and Hc values too. where can i find ?

    thank you for your help

    i just tried to add material N50 but i cant. could you tell me what i must do step by step if you know?

    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


    For N50 is
    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 ?

    For Magnetic Coercivity you must put negative value: Hc=-971 000 A/m
  13. Oct 30, 2013 #12
    ok. i will try negative value. thank you for your help
  14. Oct 30, 2013 #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?
  15. Oct 30, 2013 #14
    Of course
  16. Oct 30, 2013 #15
    I am doing design of electric machines
  17. Oct 30, 2013 #16
    i am so new at maxwell . only two moths. so my question is really simple :) i wanna do a linear motor simulation. and i am studying on


    typ: SL2-P050S-010

    motor. but my desing is not even close with it :S
    do you have some advice for me?
  18. Oct 30, 2013 #17
    Advice? :-) If you have any problems, you can ask me. If I knew, I'll help you
  19. Oct 31, 2013 #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.
  20. Oct 31, 2013 #19
    of course
