FW and MTPA characteristic


I am working with a magnet assisted synchronous reluctance motor (PMa-SynRM) and I am trying to get the constant power characteristics. Without the assistance of the magnet I obtain the characteristic constant torque through the Machine Toolkit, but when I use the magnet the characteristic doesn't give me something reasonable. Does this kit not work for this type of machine?

Could you tell me if there is a tool to calculate the constant power characteristic or any suggestion to obtain it, any idea or suggestion is good....

    Hi @Cesar

    PMASRM is also a kind of IPM machine. Machine toolkit supports IPM machine.

    So it should work for PMASRM as well I think.

    Hi Navya

    I tried to simulate it as an IPM but it gave me inconsistent results. I'll give it a try....

    Thanks for your time....

    HI @nchode

    I followed his advice and ran the simulation as a IPM machine, but the results I don't think are correct, I show you

    without PM

    with PM

    Theoretically, the torque on the assisted machine must be higher, but it is not the case...the simulation was carried out under the same conditions.

    Best regards,
