Model for Flux® Skew environment
1. Introduction
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.
All the models to be exported are first classified by considering the type of application for which they are built (STATIC or TRANSIENT).
Then, for the tests in Motor Factory Test environment, the models are associated with a convention of operating (Motor or Generator) and grouped into packages itself to get classified into model families.
In the current version of Altair® FluxMotor® 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 | Working point | Sine wave | Motor | I-Ψ-N |
The following section give a short description of all the models available for exportation to Flux® 2D environment.

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.
