DEPRECATED

Have a look at newer versions of FEMM which has many new features.

3F --- Framework For Femm

Some drawing and analysis code through FEMM 3.3

2016/08/23

How-to quickly:

1. make a copy of the folder template_motor in ./
2. rename it to your taste
3. edit motor_data.lua with your specifications
4. add, change, remove (carefully) materials in materials_and_bc.lua
5. double-click on 3Flin{.desktop} shortcut (Linux) or 3Fwin{.lnk} (Windows) [you can also look at the one which displays the icon]

Requirements:

If you're using Linux you have to install Wine and configure femme in 3F/femm33Mar/bin/.

What if:

I already have a .fem drawing

Fine, after step 2 read yourfolder/README.txt and follow the instructions.

I just want to make the drawing

After step 4 modify the variable TYPE inside yourfolder/type.sh and just put "DRAWING". Continue with step 5. Wait for it and look for the file yourfolder/yourfile.fem

After some modifications to the drawing, I want to analise this machine

After step 4 modify the variable TYPE inside yourfolder/type.sh and just put "ANALYSIS". Continue with step 5. Wait for it and look for the output file inside yourfolder/output/

Now I'd like to simulate other things/settings

Make your choices in yourfolder/motor_data.lua. You can find a record of all the results in yourfolder/output/, sorted by the date_time of launch.

I had a problem during the analysis

Try to look at 3F/log/analysis_date_time.log and see where it stopped. Then have a look at 3F/temp.fem to see the last motor analysed.

I'd like to know what all the options in motor_data.lua means

See 3F/doc/main.pdf for some of those options.

I don't understand why you made easy things complex

Generality. A unique framework for the analysis of rotating electrical machines through FEMM. Reuse of code. Easy link to optimiser (I hope).

What's next

• I have to complete the set of possible analyses.
• introduce the number of conductor in slots
• some small bugs (like air-gap closing) must be fixed.
• other synchronous machines have to be implemented, building under 3F/drawing/rotor.lua (IPM radial, IPM tangential, RELuctance, PMAREL)
• other slot shapes can be drawn (closed slot, deep bars), so extending the capabilities of 3F/drawing/fun_draw_slot.lua
• other analysis types must be created for the Induction Motor (IM), even though the common ground for its drawing is already here (apart from point 5 of course)
