Maybe it would help to know the math for the angles between coils and also magnets.  Easy enough to calculate at 45° for 8 equally spaced in a circle and 40° for 9 equally spaced in the circle.  A couple basic drafting tools (even school kids type should work) and you can do the layout.  Just put coils and magnets same exact distance from center on these angles and you've got it.  That way you don't even need to know the distance between them as long as the angles are correct and the distance from absolute center is the same.

A plea to all computer wizz kids . I would not know a cad if it jumped up and bit me . Could someone post a diagram of two circles ,with lines radiating from the centre to the circumference . One circle to have 8 spokes and one 7 spokes . Then one could print these , stick them to discs , and use them as a drilling guide for rotor and stator . Just a thought .

Did you mean 9 spokes rather than 7 ?  You do have a good idea there and if it's done as a .jpg most programs can easily resize it for any other rotor sizes being built.  What I mentioned above should cover it too and can be easily adjust for different magnet sizes by centering the magnet over your angle lines.

Neptune,

I normally do this in Excel, using doughnut graphs.
I've attached a zipped Excel file example of one you can use.
The excel example contains 3 donuts, 7, 8 and 9 segments.

The thickness of the doughnuts can be adjusted by rightclick on the doughnut graph and then click 'Format data series'. You will get a window that looks like the one below.
Play around with the sliders to get the appearance you want.
Don't use the picture of the doughnut, it's just for example, use the zip file just above the slider picture.

Hi Romero,
Congratulations!  Very well done, indeed.  Thank you for publicly showing your working replication of the Muller device.

Hi Groundloop,

Your drawing, showed the magnets between the coil ends and the rotor, in repulsion, but Romero, says he is driving them in attraction, yet approved your drawing.  I would just like clarification, and if it is attraction, to readjust the picture perhaps..     Aside from that, the picture is awesome, and a big help.  Thank you!

At ALL,
The individually stranded wire, in Romero's setup is simply reducing the resistance of the wire, allowing for greater output.  Often, coils are engineered with large diameter wire, for low resistance, but often, this results in lower number of turns, thus less inductance per coil.  This is easily overcome, by using individually insulated wire, for even less resistance, and also a greater number of turns per coil resulting in greater inductance, less resistance and greater output.  Take the resistance of the wire, for said number of feet (length) and divide that by the number of wires you are running in parallel, and this will give you the new resistance of said stranded wire.

Cheers,

Bruce

Hi Bruce,

The magnets and rotor was the only part of my drawing that I did not draw. :-)
It was a copy from Romero's drawing, so you must ask him.

Attached is the updated drawing.
