Model for Flux Skew environment
1. Overview
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 ® Skew environment.
In the current version models can be provided for static application or transient application in Flux Skew environment.
Three models can be exported to Flux Skew environment:
| Application | Model family | Package | Convention | Model / Test |
| STATIC | Without solving scenario | Current source | Motor & Generator | Basic model |
| TRANSIENT | Characterization | Open circuit | Motor & Generator | Back-EMF |
| Working point | Sine wave | Motor | I-Ψ-N |

3. Particularities in building and to exporting a model to Flux® Skew environment
A user who wants to build and export a model to Flux Skew has to follow the same steps and recommendations as with the function “FLUX 2D”.
The main particularity of function “FLUX SKEW” is that the “ Skew number of layers ” is an input, that must be defined. Its default value is 3.
Even if the design of the machine is defined with “continuous skew”, the “ Skew number of layers ” is necessary for Flux® to define the finite elements model in the Flux® Skew environment. A high number of layers gives more accurate finite elements computations. However, it needs higher computation time. For that purpose, the value 3 is a good compromise between accuracy and speed.
