Simpler way would be to do it in a way similar to Wesley Snyder. Torbay's construction, however, allows for a more powerful motor for commercial purposes.

What do you mean when you said you simulated the diagram? Did you do any calculations of the resulting forces?

Hi Omnibus,

Yes I simulated the forces that were exerted on the rotor magnet when one of the eight stator magnets were taken away. I took each magnet away to see which one would cause the most torque to be exerted on the rotor. The results were quite substantial although the numbers were not important since I don?t know what size and type of magnets he was using. However, the simulator I used (FEMME) only simulates two-dimensional setups so I couldn?t directly test the pivoting arm to see how much force would be exerted on it. I have another program that will do that but it will take some time to set up right. Plus it would be nice if we could get a rough idea of the scale of the motor first.

God Bless,
Jason O

That?s interesting. Can you do a simulation of a radially magnetized toroid  with a rectangular magnet in the spacing? Or, better yet, an 11 segment polygon (each segment being a magnet), radially magnetized, and a rectangular magnet within the enclosure?

Hi Omnibus,

Sure, draw me up a simple diagram showing what you want the magnets to look like and some rough dimensions and I'll do it. What data are you looking for? I'll have to use my 3D simulator to do the radial magnet since FEMME croaks on them.

God Bless,

After reading in some other forums in spanish and looking at his pictures I have now more clear how it works "if it works"


Hi Gonzo,
could you please scan the spanish forums, if Torbay has already posted somewhere a video
of his motor ?
That would really help, if we could locate the video clip.
Many thanks.
Regards, Stefan.

HiJason,
it could also be a band of plastic coated ferrite powder magnet strip,
these plastic band magnets so all the North poles just stick out and
no south pole half like you have drawn !

Jason, this is the toroid with the rectangular magnet. Let?s see what will come out of it. The graph with the 11 magnets is more difficult to draw. Let?s see first this one. Thanks.

Hi Omnibus,

Without even running that simulation yet, I can tell you that there is a measurable force on the magnet inside the ring when it is in the setup you describe. I've actually simulated models like this before but the 3D simulator doesn't give consistent results. From the models I have done, it shows a good amount of force but little to no torque; so in effect, it is contradicting itself. I'll try it again though with the magnet sizes you mentioned to see if anything comes of it though.

This model is definitely worth trying though  ;)

God Bless,
Jason O

Hmmmm good point. Didn't think of that. How do you think he has the magnets arranged in the rotor? I know they have the north poles facing out but any idea how many?

These plastic strips magnets is like a big rubber band.
They have a constant Northpole at the one side and
a constant southpole at the other side.
There are some, that are about 2 to 5 mm thick,
10 mm wide and maybe he gut out 10 cm long to lay around his rotor.
So if he just has
cut an enough long band ( 10 cm maybe ) out of it and layed it into
the rotor it would be like a ring which you can see on his photo.

Hi Stefan,

Ok I see what you're talking about now, I have some of that strip stuff too. But if the rotor is one constant north pole magnet, then how is the rotor going to turn? there has to be some break in it somewhere to give the magnets somewhere to want to go. Otherwise it wouldn't care if there was a break in the outer ring of magnets because the pole of the rotor would be symmetrical on all sides. Am I missing something here ???

God Bless,
Jason O

Jason, I?ve been trying for some time to set up an experiment similar to that shown in the sketch. The biggest problem so far is finding a radially magnetized toroid with good homogeneous doughnut-shape field. I have axially magnetized toroids which are the usual type. They don?t do the job. A company agreed to make a radially magnetized one for about $2000 which I still don?t find justified before I?ve tried simpler (and less expensive) ways.

So far I?ve tried magnetized plastic strips just like the ones Stefan describes, bent in a circle. The problem with these strips is that their magnetic field is too weak. Also, it doesn?t appear that the field they create is homogeneous. I?ll get my teslameter in a day or two (unfortunately I don?t have with me now) to see what?s with the field. It appears that overall the field created by this strip, made into a circle, has poles. The rotor turns and sticks at a certain position.

This puzzled me. The doughnut shaped field should be axially symmetric and it appears that some unsuspected overlapping of fields had occurred which creates ?superpoles?. I don?t understand that. More likely, that problem appears due to inhomogeneities in the strip.

A similar situation is observed with a polygon made of 11 RadioShack magnets. The field is much stronger now but again appears non-homogeneous (in addition to that caused by the polygon). It appears that the individual magnets differ in strength quite a bit which may be the cause of the problem. Hope to be able to find better matching magnets when I get the teslameter.

With this 11 magnet setup the rotor again (as with the plastic strip) turns and stops, stuck at those newly created poles. When I hold this 11-magnet stator above the rotor I?m able to make the rotor turn by slight motions of the hand (which some suspect, I think unjustifiably, Snyder does in his video). This, of course, isn?t what we want.

It?s interesting to model this and I appreciate your effort. It, of course, puzzles me too that the model shows a good amount of force but little to no torque. What is the basis of this modeling? Is it based on finite element method or has some other underlying method? Could it be that for some reason that particular shape (toroid) couldn?t be modeled properly?

Aparently there was a video on the web some time ago with the motor turning, but it is not there.
The video has been criticiase because it only shows the motor turning over grass and they asked him to lift it and show the bottom part of it.

I am going to check again to see if there is something new or I can get a copy of it.
