Virtual replication of RomeroUK motor/generator by 3D FEM modeling

[toranarod]

Ansys Maxwell is a stand alone program that can be linked to other simulation software of Ansys (so, its compatible with those).
Keep in mind Maxwell is extremely expensive, around 50k$.
It's the best 3D software available for these kind of simulation in my view.
Most of the high tech mechatronics companies use it for professional modeling.

well done teslaalset
this is the kind of RND the OU motors need to establish operation parameters. thank you
I will be recording any data you present.
please keep us informed and break it down into Lay persons speak so we can all get our heads around this.

You're welcome.
As I am a rather distorted EE (), I may be going too fast with my explanations for some of the readers here.
If you need deeper explanations, let me know, I'll try to simplify my findings into the desired layman level.

Teslaalset,

I second toranarod.  Many thanks for providing the "charts and graphs" of data.  This is what I, and possibly many others, have been waiting for (second best to another self-runner).  Maybe it is the engineer in me...

Replicators, don't get me wrong.  I am also very appreciative of all your hard work.  I have even tried to get something(s) together to do some testing.  But my goal was not to replicate, but instead to investigate first.  And then "design" something to harness the OU effect.  So that would require testing and data collection while making measurable and tiny adjustments of parameters (dimensions, rpm, etc.).  I thank you for providing your input, but they have been single data points (and more than I've accomplished).  Teslaalset has shown how small the window is for finding this effect.  No wonder no one had stumbled upon it with their replications yet!  But now we have a finding that may allow you to design a device with the correct parameters.

Teslaalset, please continue.  Any and all data that you can share is greatly appreciated.

M.

@teslaalset

great simulations !

Well, could you also show a real 3D view of the flux lines inside the whole
motor when the rotor turns or does this animation take too long to calculate ?

Maybe just do single frames and then do an AVI encoding
of all the frames by a BMP to AVI (XVID codec) encoding program or
just import the single frames into Microsoft Moviemaker
and encode them to WMV or something like this.

I would really love to see a spinning rotor and see all the flux fields in 3D view.
Can you also change the camera position over time, so you can make a roundview
trip around the motor ?

Or does Maxell only show the flux field with these vector arrows ?
This would be too bad, as it is not so good in my opinion and hard to see
then...

Also your GIF animation example was only a 2 D side view and not a real 3D view I guess ?

Would be interesting to see the real inner flux field of the ferrite core in 3D.


Many thanks again.

Regards, Stefan.

I'll see what I can generate this week. I don't expect much of a difference to show the flux in the ferrite of the whole rig compared to the single module I showed in my first posting.

Maybe just do single frames and then do an AVI encoding
of all the frames by a BMP to AVI (XVID codec) encoding program or
just import the single frames into Microsoft Moviemaker
and encode them to WMV or something like this.

I can generate AVI files too, but they are much larger than the animated GIF.
I will post an AVI later this week.

Round trip is simple, this only requires 22.5 degrees of simulaton and then loop it.
I'll post it.

There are 3 types of vectors possible, but also just coloring grading the investigated element.

The simulation was done in 3D, but I showed 2D view because in my opinion this was the most clear view. I'll post one in 3D, so you can see the difference.
