Three Layer Disk Magnetic Motor

[Lunkster]

Hello
Interesting. The rotor has no elktro magnets. Why the contacts? Is it possible to use square magnets? I would be able to build that. How many windings would the electromagnets have. The book would also intrilate me.

I show the electrical contacts because even though there are no electromagnets on the rotor, the electromagnets operate at a 25% duty cycle.  Half of the electromagnets are on a different timing schedule.  So it is only for signal purposes in the circuit.  Reed switching or optical switching are other options.  Both of them need a mechanical way of signaling the position of the electromagnet set needing to be energized.
Yes square electromagnets would likely work.  THe shapes and size of both the electromagnets and permanent magnet can be played with.  The way I drew it was to get the most power out of the design.  Other shapes will work, but it may be at the expense of the motors efficiencies and performance level.
Another note is the drawing says imbedded electromagnets.  This is also just a suggestion.  One way to make this assembly is using two plates cut so there is a solid backing behind the electromagnets.  The second plate could be cut so there is a ring on the top side and a ring on the inside of the electromagnets and permanent magnet holes.  I just think extra strength in the disks is important.  WHen I built a different prototype design using 21 inch disks, the permanent magnets were so strong in the interactions between the rotor and stator assembly, that there was a lot of warping in and out of the disk with rotation.  One part of my thinking is to use aluminum plates, but I have read that eddie currents occur during the rotation.  SO maybe someone else may have a better idea of the materials that should be used for the motor. As for the hardware I used aluminum threaded rod cut to size and double aluminum nuts. 

As far as the electromagnets number of windings go, You need to have the power of the electromagnets to match the power of the permanent magnets.
If custom electromagnets are built, then the gauge of the wire along with the wire length and the number of turns need to go into the calculations.  I am not the person to answer this question.  I am sure there are other people who can answer that question.

thank you The Lunkster, like I said I want to try, build if you will assist me, I have a 3D printer, neo magnet and copper wire, I also have a mechanical lathe at my disposal . I will be interested in your book, if you can give me a clearer diagram, and all stages of the construction starting with the first part to build.
best regard sti

I will work on putting together a parts list and drawings of the sub-assemblies of how I would build the prototype if I were to build it today.
This will take me a little while.  I want to use as many current parts on the market and reduce the custom parts as much as I can. 
This can take a lot of on-line searching, but it will be well worth it in the long run.

OK thanks for sharing I'll wait when you're ready

I am filling the request for a parts list with more information.

As I was putting together this list and assembly notes, I improved upon the design by using many off the shelf parts to build it.

I incorporated reed switches to indicate the location of the rotor for both electromagnet circuits that operate at a 25% duty cycle on a different switching schedule from each other.  The location of these switches can be moved around in order to optimize the performance of the motor during the operation of it.

I have improved the adjustable Stator permanent magnet plate assemblies for there location in relationship to the rotor permanent magnet disk in order to optimize the motor performance through adjust and test sequencing.

The motor is inclosed for safety and structural integrity.  The front panel can be hinged for access to the inside of the motor.

I had the goal of these attached files of allowing other hobbyist like me to be able to build it with minimal machining tools.
