Lengths in the 3rd dimension
Particularities in building and exporting a model to Flux® 3D environment
A user who wants to build and export a model to Flux® 3D has to follow the same steps and recommendations, as with the function “FLUX 2D”.
The main particularity of function “FLUX 3D” is that rotor and stator axial lengths are inputs, that must be defined. Their default values equal the machine length defined in “Design”. These two lengths can set to different values.

To reduce computation time in Flux® 3D, full geometry and symmetry options are offered. By default, these options are set to assure minimum computation time without accuracy loss. |

Symmetry allows to represent only half of the topology in the axial direction, saving the simulation time. This option is available only when all the dimensions are equal on both sides of the machine (Connection Side and Opposite Connection Side), especially for the end winding and the rotor end-ring dimensions.
A warning message is provided in the “Design environment” each time an asymmetric topology is defined, to inform the user that the Flux® 3D export input “symmetry” has been set to “No”. This also occurs when the asymmetry is due to the end shafts, even if they are not represented in the 3D environment.
