4X3 Permanent Magnet Motor concept

[tishatang]

Hi all,

I really like this forum.  If my idea for a permanent magnet motor is to be realized, it will be here as a collective effort.  Also, if my logic is faulty, it will be revealed before energy is spent building a prototype.  I will have to describe my process of thinking step by step as I do not know how to draw using the computer.  This motor could possibly a self-runner, or at the very least, a highly efficient, high torque pulse motor. It should be relatively easy to build compared to some other designs.

To show then motive force I employ, you will need 30 or 40 neo or ceramic disc magnets 3/8ths to 1/2 inch in diameter and about 1/8th inch thick.  You will also need two ceramic rectangle hobby magnets about 2 inches by 1 inch by 1/4 in thick.

To simulate the rotor to stator relationship, I used two clear CD blanks that were protectors in a CD-R bundle.
Using a felt pen, I drew different rotor/stator configuations that I could superimpose and rotate until I determined the ideal was 4 rotor poles and 3 stator positions.  Hence the title 4X3, or if a pulse motor 4X3=12 pulses per revolution.

To build the motor described, you will need 100 to 150 disc magnets and 8 rectangle magnets.  All plentiful and cheap, nothing exotic.

The latter is good also for optical sensors and other things of interest.

It has been a long day for me.  I am putting a new roof on my humble abode and tomorrow is another long day.

I will post again tomorrow and walk you thru the process.
Thanks,

Tishatang

Listening.

If you could draw a picture on paper and scan it in that would be cool. I'm no good a drawing with a mouse either so I understand your dilemma. For me, my surfing hand is my right hand and I write and draw with my left, so it's no good.

Anyway, we'd like to hear your design.

If you do sketches and descriptions I can help with drawings if needed.

I have Solid Works (3d), Solid Edge (3d), and Autocad (2d).

If we go farther than drawings, I usually have idle machine shop equipment.  120x60x30 CNC mill (router - non ferrous & plastics - no hard metals) - Standard Bridgeport mill, small lathe, small surface grinder, bandsaw, misc power and hand tools.

I can handle most any type of data files to machine from.  STL and Iges work particularly well in most cases, but I can take any common format to work from.

If anyone has legitimate, promising looking projects, I am interested in helping in any way I can, as I have time.

I think an "open source" project of some kind would be a great thing on this forum.  I am eager to participate if we come up with the right project.

I am eager to participate too with my turner,
mill machine and tectronic osciloscope .
We have to find mag motor solution.

magnetism is amazing
