📂 Exporting the FMU Block for Motor Models

This paragraph explains how to export an FMU (Functional Mock-up Unit) block, which is available in both 2D and 3D versions of Flux. To generate this, a parametric scenario must be solved. The user can then export the FMU block by selecting the appropriate options in the data exchange menu, providing the name and path of the block, and configuring input/output parameters. An example application of the FMU block is demonstrated in Activate, where the block can be edited and validated for system-level analysis.

Keywords

💡OML File

An OML file is a format for exporting data in Flux, a software for electromagnetic and thermal simulations. It allows the user to export data from a project, such as 2D, 3D, or transient models. In the video, the OML file is discussed as a key export option that can be generated by solving a project and selecting the export format from the data exchange menu.

💡FMU Block

FMU (Functional Mock-up Unit) Block refers to a data block export format that can be used in system-level simulations. The video explains that this export option is available in Flux, allowing the user to generate FMU blocks from a solved project, which can then be used in co-simulation environments like Activate and Compose for system-level analysis.

💡Lookup Table

A lookup table is a pre-calculated data set that allows for quick retrieval of values based on inputs, often used to simplify complex models. The video describes how lookup tables are generated from Flux or Flux Motor projects and can be used to represent motor characteristics, such as torque or inductance, as a function of current and rotor position.

Transcripts

hello everyone thank you for

participating to this web about reduced

model of the motor during this 10 uh

first minutes we will see the

possibility of generating the lookup

table using flux and flux motor the

first part we will see the different

possibilities available in flux in Flex

there is several format that we can

export like oml file FME block CSV file

txt file and lookup table we start by

the oml file since several versions of

the flex this feature is available

directly in the interface it is

available also for 2D q and 3D modules

to generate this oml file a paramet

scenario must be

solved once the project is solved to

generate the export in flux there is

there are some steps that the user

should follow first one the Sol solve

the flux project go in the menu data

exchange click on export data table a

new window will be opened we select the

form of the file that you want to export

to activate or compose we select also

the folder where the file will be saved

we select the input and output

parameters in the list and as the last

step we Choice the values the type of

the values to

export once this is done now we will see

the different steps to use this file

inside activate and compos we start by

activate in activate the file or the ml

file and activate project uh should be

in the same uh

folder aside activate in the menu

diagram home you choose the context tab

you provide the name of the file create

by flux and as a last step you check if

the variables were located correctly and

say compos there is directly a

possibility to open this oml file

without

any additional

steps the second possibility is to

export the fu block this also this

feature is also available in Flex since

several several versions it is available

on 2D skq and 3D modules to generate the

F block pared scenario must be

solved once the flex project is

solved to generate the fmu block we

provide uh we go to the data exchange we

select directly the export fmu block new

window will be opened in this window you

will provide the name of the block

the path to the folder in which flx will

create the FME block you Choice the

input in the Block in the parameter of

the Block in the parameter list we chose

also the output of the block among the

input output parameters and the

sensors in this next slide uh an example

application of the FM block I said

activate you have your model you create

the blocks for

fmu you edit the S fmu block you load

directly the file that you have created

previously in flx and you validate this

is just to show you the the use of this

fmu

block the latest uh way to create a

lookup table is to use a macro the goal

is this macro is to create a lookup

table from a transient uh application or

project the lookout table that you get

from this macro are for Flex in DQ AIS

the inductance in DQ

AIS uh the torque uh also all these uh

performances are function of the current

in D qais and the rotor

position there are three macros

available currently in Flex one for 2D

one for 3D and one for

theq all these macros as mentioned

previously the aim is to create a lookup

table of the flux in DQ axis and DCT DQ

axis the torque as function of the

position and the current in the qais

just here to give you a small details

about the principle of this macro from

uh transient project we load this macro

we random the macro behind we create a m

static application or project and from

this one we can get all this all these

Maps there is a possibility also to

write the results as a mat file and this

mat file can be read by flx activate

P the goal of this macro is to make a

system analysis of the imotor

AER in this slide we will see the steps

that the user follow to use this micro

inside the flx once your project is

solved in a magic trans project you load

the micro you run the micro when you run

the micro there is some data and some

data that you need to put to run this

mcro in this last last slide we will see

some uh some results that we can get

using this macro in this case we have

some maps of the flex in D and qais and

the talk one recommendation when you try

to use this mcro it's really recommended

to use a parallel computing why because

this lead to decrease the time and save

the correct and decrease the time

computation this is about the different

possibilities to export oml fmu and

create lookup table from

flx now for the next step we'll see the

different possibilities also aside the

flux motor to create this lookup

table in Flex motor uh the user have a

possibility also to export directly a

lookup a lookup table this lookup table

can be used by Al flx so activate and

compost the goal also as mentioned

initially for case of flux is to use or

to simplify the motor to use it inside

the system system level and to make more

easier the analysis of the motor

consider

the system or the

control in Flex motor if the user want

to export lookup table he open flux

motor or motor Factory from motor

Factory he select the export area and

from the export area have directly

access to the look up select option

lookup table

export and from this one you can export

different the data or the lookup table

that he want for for this

motor now to export this lookup table

there are some steps that user should

follow the first one is the test

selection one test can be selected

currently is the maps from the

characterization model motor you have

possibility to select the maps the test

uh the test configuration as a second

step for this

one user will Define the working

condition of the

motor the third step is the export

information for this export information

also there's some steps I say the first

one is the definition of the name of the

lookup table also there is a possibility

to select the Forma currently we

have fmu block dedicated to activate and

P Fu block generic and also there is a

possibility to generate or to export a m

five once this is done the user validate

and Export C to export this uh this uh

lookup

table just here some details about the

different format that we have currently

available in Flex motor the first one

fmu Forma there is

two two fmu forat the first one is uh

dedicated to activate and PC and the

second format is generic compatible with

other system simulation tools the second

possibility is to generate direct

directly a mat a mat format or M file

this mat file can be implemented in the

environment like PCM and uh PCM activate

or

compos the latest information that I

want to share with you is about the

Improvement of the export system table

and say the flex motor with the latest

version there is another possib

possibility to consider the rotor

position or the rotor dependency as you

can see from the test configuration from

the input there is possibility to to

consider uh the rotor position the goal

is to make more accurate accurate

results this is the possibility to

create or to generate a lookup table

from flux

motor thank you for your ATT sh
