Motor simulation in Maxwell

  1. Nov 9, 2018 #1
    Hello,
    I'm trying to simulate a 3 phase hysteresis motor with 4 poles, 36 slots, 220 input voltage peak for each phase, 50Hz, specified dimensions and 0.6 N.m output torque in maxwell transient.
    The magnetic material used is LNG52 which is also known as alnico600, alnico5DG(ACA52) and alcomax 3SC.
    The rest of specs like efficiency or number of turns aren't presented, however the results are:

    This is the simulation file.

    The problem is that my results no matter what the number of turns or efficiency are, are nothing like what they supposed to, for example the starting torque is so much lower and motor reaches the synchronous speed much much faster about 10 to 5 times faster than it should.
    If you have any thoughts what the reason might be, it would be much appreciated.
    kind regard,
    Omid Feyz Najafian

    I can't view the links. There seems to be a paywall. Please use the UPLOAD button to post the content you want us to see, or paste it in the post as text between CODE tags.

    Dear anorlunda,

    I'm sorry for the inconvenience.
    These are how the results should be like:

    I am not going to load and execute a program from a link. Can you post the source code as text?

    Dear anorlunda,

    Please explain how I can access the source code from a .mxwl file to send it in text format?

    best regards,

    I am not Maxwell knowledgeable. I'm just trying to help other PF members who might be able to give you an answer. They need to see something posted they can comment on; not an executable file that might contain malware. By source code I mean the data and instructions that you typed into Maxwell to set up your simulation.

    Dear anorlunda,

    Thank you for the tips.
