Hello All,

here is a torque analysis done on the first simulation file posted bu Vidar. I increased the mesh size to 0.3 for all block labels and did a block torque analysis only on the two magnets rather than a line integral around the whole rotating part. There are 72 torque points plotted, meaning the measurement was taken every five degrees around the circle for the total 360 degree rotation.

There is definitely a clear offset on the graph though I wonder if the total area still integrates to zero. I'll be happy to see how the one with three rotors works.

God Bless,
Jason O

Hi Jason,
many thanks for this fantastic fast result.

Could you do some kind of script calculation
over one cycle and see if the area under the curve
in the positive range is the same area as under the zero line
in the negative range ?

If both areas are the same , the torque adds up to zero and
the motor will not run.
It could be that it really adds up to zero from your posted graph.
So we would need to tweak the design, so that it does not add up
to zero.
This could probably be done by overlapping rotors or
added flux diverser iron pieces inside the stator or rotor, so the negative torque would
not be this big in some places...

Regards, Stefan.

Hi Stefan,

Attached is the Excel file I use to generate the torque graphs. I input the torque data files from the simulation and it will automatically format the output for me. There are also a few tables on there that show the total positive torque points, the total negative torque points, and an average of the two. This is just an approximation of the area of the graph to show if it is more positive or negative.

It is showing that there is slightly more positive (0.7%) but since the ratio is so small, I'm willing to bet that there is an equal area around the graph. But, even with that, it is the negative spike that I am interested in. Because of what I talked about in my 90 degree rule article (www.fdp.nu/free_energy.asp?book=90), it is the spike that we want to bring in the extra energy into the system. Check out the article for more info.

Also keep in mind that the simulator cannot account for the many complex magnetic effects which could allow this to work. So I wouldn't get discourages just because it doesn't give positive results.

God Bless,
Jason O

I believe the simplest way to see the total torque, is to replace the two or three rotor parts with one single toroid - a ring shaped iron piece surrounding the inner permanent magnet. Then you have in theory an infinite number of degrees to calculate the average torque. If the magnetic field through the iron ring, in any way, will force the ring to rotate one way, one can probably make a working model.

Unfortunately the femm file for my last three pole motor does not longer exist. Femm has the great feature which don't ask you to save the file before closing if you have done changes to the previous saved model. So now this motor is suddenly a total different model without asking me first... ::)

what software is being used to produce the images and torque numbers.

Hi d3adp00l,

I created the torque data files using a Lua script I made for FEMME. The graphs are made inside a Microsoft Excell spreadsheet.

Hi d3adp00l,

FEMME (Finite Element Method Magnetics) is a freeware electromagnetic simulator that Vidar and I used to do magnetic simulations with. You can read more about and download it here:

Not FEMME (French: girl) but FEMM ;)

Anyway, Femm 4.1 can be downloaded for free at this site:

Well I can make little rectangles but thats about it, its a bit over my head to use. But thanks for lettin me know where it was.

Look at the tutorial how to do it. I did and after just a few minutes, and a few questions here, I can manage to use it, measure torque, force etc.

You first have to make a square or a circle where the device will be inside. Use the point tool to click four points where you then use the line tool to draw a line between the points. You are now creating a space where the device can work in.

I will watch the tutorial and take notes. Thanks, I have the start, I am kinda excited after about ten years waiting to figure out how to create the field I needed I get try and test it.
