    Hi,
    When you create your part starting from Flux, the more drawback of this method is that your part is not parametrized. For this reason you don’t get any parameter on yyour excel file.
    If you want a parametrized part, you need to create your own excel file using an excisting part (issue from FluxMotor).
    Attached an PPT file explain how to create  a parametrized part in FluxMotor.
    Best regards.

    Hi,
    In the case of stranded coil in Flux 2X, if you don’t put any information about the material, this means that the permeability that you use is 1 (in other hand, thsi means that you use air as material).

    Best regards.
  3. RAVITEJA_028 liked a post in a topic by Abdessamed in How to compute torque on a brushless with sensor   
    Hi,
    To compute the torque in Flux using a sensor you need to create a sensor. To do it:
    In parameter/quantity j, create a new sensor Type of sensor: predefined, magnetic torque Rotation axis:     Direction: parallel to oz Pivot point (0,0) Computation domain: select a face region. Other way to compute the torque is to draw a 2D curve of torque. To do it:
    Curve 2D curve (I/O parameter) >> new >> mechanical set >> select electromagnetic torque To use this data in Simulink, you can export this curve as txt file. In you Simulink model you can use a look up table to read this txt file.
     
    Hope this will help.
    Best regards.

    Hi,
    To find the value of the data that you need to use, you can use  the following formulas :
    For example for the inertia :  J=(1/2)*M*r² where M is the masse and r is the rayon.
    For the friction : F=(torqur/Speed).
    For the velocity and speed a t=0 you  keep the initial value zero.
    Best regards.

    If I understand you want to take into account, the load and see the starting of the motor? If it is the case, you can use “coupled load).

    Hi,
    Can you try with imposed speed. in the mechancial set rotor use imposed speed and put the value of your speed.

  7. pontusf liked a post in a topic by Abdessamed in ORIENT MATERIAL FOR FACE EGION   
    Hi,
    A permanent magnet is characterized by remanent induction (Br). To represent a permanent magnet in Flux we need:
    The type of magnet (linear or nonlinear) Magnetic proprieties (remanent induction and permeability) The orientation of the magnet (sense of the remanent induction on the magnet) From Flux if you want to see the orientation of the magnet, from the tab “physics” select ‘display arrow on the magnet’. This give you an idea about the sense of the remanent induction inside your magnet.
    In your case, to define the orientation of the magnet, you can create a coordinate system in each magnet, and assign a value of the angle according to the coordinate system that you have created.
     
    Best regards.

    Hi,
    From Flux supervisor, you select option. After you go in access path, you select coupled software.

    Hi,
    You get this error message when you try to solve the project? In this case can check your physics you sing the command “check physics’ from the menu physics, if you get an error message, you need to see your physics (for example assign of mechanical parts). Once you have corrected all the error message, try to solve the project. If the problem persist, send us your Flux project (zip format).
    Best regards.

    The link does not work. can you send us your project again?

    Hello,
    Sorry for the delay. In this case you need to put 359.999 Degree and not 360 degree becasue if you put 360 there is a superposition of points.

  13. EmSt liked a post in a topic by Abdessamed in Nonlinear magnet described by a spline - Transversal relative permeability   
    Hello,
    In the case of nonlinear magnets, the value of the permeability it is not the same thing in both axis (x and y axis), the value of the axis parallel to magnetization is different from the value of the other axis.
    A link to see how we calculate the transversal relative permeability:

  14. EmSt liked a post in a topic by Abdessamed in Non meshed coil: Difference line - rectangle   
    Hello,
    The difference between both non meshed coil with rectangle coil section and with line coil section is located in the current distribution. With the recangle coil section you have the current in the all volume of the coil. But in the case of line coil section , the current is ditributed at the surface. To see this, yu can create tow coils; with rectangle and line section. Do a simulation and plot the current density.

    Hi,
    In Flux you have the possibility to launch many Flux projects in the same time using the batch solve.
    In the Flux supervisor, below the “python script”, you have “Batch solver”. Once your project are ready, you select “Batch solver” and select all the projects after this, you click on the “Solve several projects” (this command is located at the bottom left of the supervisor).
     
    Best regards.
  16. EmSt liked a post in a topic by Abdessamed in error: no materials database   
    Hi,
    To increase the numerical memory in Flux you, in the option you select memory.
    About, the error message, I Checked when I open the options >> Materials, I get any error message. But, in your materials database for import in Flux you have any link inside (see the attached picture). I think for this reason you get the error message.
    Can you check if you have installed all the files correctly (see attached picture)?
    If it not the case you will find attached the files. You need to load all the files.

    Hello,
    Sorry for the delay.
    The error message mean that in your solving scenario you try to you have defined a parameter that has no effect on the geometry when you change the value.
    To change the position of your block, in the solving scenario you need to select the mechanical set free and you have to impose the lower limit and high limit.
    Best regards.

    Hello,
    The error message mean that you need to separate the moving part and fixed part.
    I made some modifications on your Flux project. You will find attached your project ready to mesh and solve.

  20. fezusa liked a post in a topic by Abdessamed in Problems with my simulation   
    Hello,
    You will find attached to this email an example of what you want to do. In my case, I create three blocks, each block I put a material and a mechanical set (the aim is to separate the moving and fixed part). I create three mechanical sets: fixed, moving (translation along one axis) and compressible (the aim is to re-mesh the air around the moving part). In the end I create the infinite box and I put fixed as a mechanical set.  With all this modifications I reached to solve the project without any error message.
    In your case, you need to create a volume around the moving part and put a compressible as a mechanical sets. Also beware about the unite that use, I mean by this
     
    Hope this will help.

    You are welcome.
    Yes it is possible. To do it, one the project is solved:
    In data exchange, select export quantity and after select export spatial quantity and formula starting from different types of supports Flux open a window (see attached PPT file) With this method you need to do the same step for each region.
    In the new Flux version (2018), you can do it by selecting all the region in the same file.
