Export to Flux 3D is available

The export of project from FluxMotor to Flux 3D is now available for both types of machines, Synchronous Machines with Permanent Magnets - Inner rotor and Reluctance Synchronous Machines – Inner rotor.

The aim of this export is to provide a python file which allows to get a full parametrized model ready to be used in Altair® Flux® 3D environment or to directly get into Flux 3D for solving and postprocessing the resulting 3D project.


Export project to Flux 3D environment – Export information
Note: In the current version one basic model (with a current source) can be provided for static application, without solving scenario.

While exporting the project from FluxMotor to Flux 3D, after having defined the project name and the folder in which it must be stored, the user has two possible choices to make:

  • Export a full geometry or not. If the answer is “No”, the resulting project in Flux 3D is a reduced one in terms of periodicity based on the number of poles and the number of slots.
  • Consider half the topology along the axial direction or not. If the answer is “Yes”, only half of the topology is represented.
    Note: This is possible only when all the dimensions are equal on both sides of the machine (Connection Side and Opposite Connection Side), especially regarding the end winding dimensions.

    If the answer is “No” the whole machine is represented along the axial direction. This allows to consider the differences there can be on both sides of the machines especially regarding the end winding dimensions.

A dialog box is provided for defining the lengths of the stator, the rotor, and the magnets. These three lengths can be different.

The illustration here below shows the resulting topology in Flux 3D environment where the three lengths are different. This is automatically managed and built from the export area of FluxMotor.

Note: The export to Flux3D is also available for Reluctance Synchronous Machines.

Warning:

When a motor with a skewed topology is considered, on rotor side or stator side, the export to Flux 3D is not possible. In that case, only the export to Flux Skew is accessible.

When the machine topology is not symmetric, especially, with the end winding lengths, the whole the machine must be modelled in Flux 3D. The choice Symmetry “Yes” is not available

In that case, end-windings can be represented with different dimensions on the “Connection Side” and the “Opposite Connection Side” like what is represented in the picture below.

Note: A warning message is provided in the “Design environment” each time an asymmetric topology is defined. This is for warning the user, that the default value of the export inputs dealing with the symmetry has been set to “No”. This also occurs when the asymmetry is due to the end shafts, even if the end-shafts are not represented in the 3D environment.
