Seems to be an issue with compatibility of PMSM (FluxMotor) block with LUTs exported from FluxMotor 2023

Since exporting LUTs (lut_maps.mat) from FluxMotor 2023, I am getting this error in PSIM with the PMSM (FluxMotor) block: "Name: LKUP3D_MAT Can not find GRAPH_output axis: LOSS_IRON in Graph file"

    Hi Chris,

    Thanks for reaching out!

    At which stage of your workflow did this error occur?

    Did it happen immediately upon starting the simulation? -> possibly an import issue

    Or did it occur while the simulation was running? -> possibly a problem with the working range

     

    BR,

    Hi Nikos

    It occurs immediately upon starting the simulation. It seems that the export of the iron loss components has changed for FluxMotor 2023.

    Thanks

    I checked that the same error occurred.
    The error message is the same.

    Hi Chris,

    Looks like an error in the process of the .mat file generation from Flux. Is this specific to FluxMotor 2023? Can you get this to work with version 2022.3?

    Thanks for sharing this! Is this a FluxMotor 2023 related issue for you too?

    So am I.

    There was a problem with Flux Motor 2023.
    I haven't tried the 2022 version yet.

    Hi Nikos

    Yes, seems specific to FluxMotor 2023. It worked fine for me previously.

    Thanks everyone for your feedback on this. It seems to be a bug with FluxMotor v2023.

    I will make sure to document this issue in order to get that fixed.

    Best regards,

    Nikos

    Hi all,

    I'm getting in touch to offer a workaround for this issue. FYI we anticipate it will be resolved in FluxMotor 2024.

    It seems the issue is due to a difference in the name of "iron losses" and "torque" headers.
    With FluxMotor 2022.3 it was LOSS_IRON
    with FluxMotor 2023, it is LOSS_IRON_STATOR.

    ______________________________________________________________________

    With FluxMotor 2022.3 it was TORQUE 
    with FluxMotor 2023, it is ELEMENT_TORQUE_ELECTROMAG.

    _______________________________________________________________________

    As a workaround, you can open the .mat file exported from FluxMotor using Compose and the MAT Explorer tool. From there, you can rename the headers accordingly. Once modified, you should save the altered file using the save('path/name.mat') command.
