Modify/create magnets shape FluxMotor

Hello,

I posted recently a question similar to this but a bit different.

Since I could not find the V-magnet shape in Halbach array with segmented body, I am trying to design it myself.

But I can not find de way to create it. I start from a Vblok_02E excel file from FluxMotor then I want to make that magnet segmented. Each one of the them divided in 4 equally parts, something  like this

If somebody could help me it would be great.

Thank you in advance

    Hi Alvaro, 

     

    I already answered you the previous question, but now, i can see what is the shape of magnet you want to use for halbach magnetisation.

     

    If you did not manage to use the excel file to create this part in FluxMotor, may be you can use Flux 2D to create the magnet geometry and use one of the following dedicated macros:

    They are available in Flux 2D, and they allow you to create dedicated part for magnets and slots. These macros will generate an excel file that you can use in FluxMotor.

     

    I hope this will help you

     

    Best regards

    Hello Alvaro,

    i tried to simulate this type of rotor in the past when this Tesla Model 3 picture was released. I built a similar part to put into the prius motor of FluxMotor. Here is the Flux model with the sketch if you want to modify it and the part I had created.

    My conclusion was that even trying all sorts of angles, there was almost no interest in having the magnets oriented differently than the original Prius one. I think 4 magnets is not enough to build this effect. Maybe 5-6 magnets could have better impact. Another impact is magnet losses that might get reduced at high speed but a proper 3D model would be needed to asses that in a better way.
