Translator eccentricity of axisymmetric actuator
I would like to quantify the effect of the eccentricity of the translator of the attached actuator.
The device is a 2-D axisymmetric reluctance actuator. The attached simulation only contains the permanent magnet, the pole shoes, and the core. I am only interested in the effects between the permanent magnet and the steel parts.
I failed to create a 3-D FLUX file that captures the eccentricity of the translator (composed of the permanent magnet and the pole shoes).
Any help would be appreciated.

Hi,
You are right to study the eccentricity in this case you need to represent your device in Flux 3D. Can you tell me what is the difficulty in building the device in 3D?
You can use a transformation type “rotation” to build the device.
Best regards.

Using the `rotation` transformation, Flux throws an error upon the creation of faces and volumes.
Moreover, a rotation uses a line of symmetry, so for the mover and the region of compressible air around the mover, this transformation cannot be used.

Hi,
To create the 3D project, I exported the file form Flux 2D as STEP file. And I import the file in the 3D project. Using the modeler 3D create the device.
You will find attached the 3D project.
Best regards.

Dear @Abdessamed ,
Thank you for your efforts to help me.
I took a look at the file that you uploaded. The file indeed represents the 3-D axisymmetric implementation of the device that I uploaded, however, all geometric parameterization is lost.
Note that for this 3-D study, it is instrumental to preserve the possibility to adjust the geometric parameters. At least the parameter `ECC' has to be available for adjustment. This because the goal of the 3-D analysis is to study the effect of shaft (and thus translator/mover) eccentricity on the radial attraction force between the stator and the translator.
Perhaps @lombard can help me out? Or @Alejandro Rodríguez ?

Hi,
Yes. the goal is to show how to create the 3D project.
Best regards.

There are an examples in Flux supervisor which show how to create a parameterized geometry in Flux (you can see the example: exampel 3D, magnetostatic static application sensor).
Best regards.
