Possible Magnet Motor Research Ideas
« on: May 28, 2020, 05:57:01 PM »
Floor invited me to join his builder's section of this forum to share some of my videos and testing I have done.  I was inspired by his PDFs and his videos to start experimenting with magnet interactions.  Also user Norman's testing and ideas inspired me further.  And both of them have been encouraging to my testing.


My testing and experiments are rather sporatic because of things in life that need to be done.  So I may work on ideas for a month or so and then have to take a break for a month or so while catching up on other things.  I make NO claims of having discovered OU but some of these tests have been very interesting.  At least to me, as they have show some interesting interactions between magnets that confirm some of the observations made by Floor.


I will now share some of the videos I have done over the past couple of years while researching magnet interactions.  I have had to take a break for a while now to catch up on a lot of yard work that needed to be done.  But it is raining today so I thought I would post some of the videos I have already done.  I have made another device for testing purposes but have not had time to make a video of testing it.  It has not yet shown any OU but maybe it can be made to self run with more work put into it.  If any of the videos inspire you to try working on something or you see something in one of them that you think I could change to make any of those devices work better then feel free to comment and make suggestions.  If you are sure magnets CAN'T do work then don't waste your time or mine commenting.  I am NOT sure they can do work but I am willing to keep testing until I can prove it to myself.

Floor removed 2, not working video links from here, at request of CITFTA.

  Thanks for posting the videos again. As I watched them again, I formed an experiment that needs to be done. Now that I have a 3D prtr, that will make this easy. You posted that it took only 7 grams to pull out the center magnet when the others were in full attraction to it. That is far less to the 1lb 5 oz of force to close unshaded. That is a mag switch if I have ever seen one.

Here are the proper links for the last two videos I tried to include in the first post.  I am still learning how to use Vimeo.  Sorry for the confusion.

Hello Thay,


Thanks for your comments.  Are you planning to do that experiment?

CIFTA's  first 4 videos are this design.

Yes that is the one. Only difference will be stronger magnets to see how they react to the same exposure. Though they will not be allowed to touch each other. N45 neos tend to break apart when that happens. Once that is done, that will make the decision to progress to the next level of the setup.  I do have 16 8mm ss rods and linear bearings at hand so will use them for this.

@ Thaelin

If its to be a build of an actual "user floor's design" then please understand the magnet configurations are as in the drawings below.
                        The shield magnet is actually two magnets. 

                   Best wishes

@Floor:
    My setup will be along the lines of the drawing on post #4 and not like #6. If that makes me non-compliant here, please delete.

@Thaelin

It's not like that.
Its not my call.  In CITFTA's topics, its CITFTA's call. I have no authority here except to do CITFTA's bidding. This is what I have offered, for up to 5 users on the MMM-2 builders board. 

In MY OWN TOPICS on the MMM-2 board, I will do my own bidding / moderation.

If it WERE my call...  I would say build CITFTA's build ( post #4 ).  This is CIFTA's topic.  CITFTA has done a great job in his builds, nice presentations too. In short he's rocken it.  He has my gratitude and deserves all the attention to his topic it can get.

notes to Thaelin / CITFTA

1. Maintaining good pecision of alignments become MUCH more difficult when the forces are as great as those which can be exerted by Neo magnets.   There are powerful lateral forces against the sliding systems (Luke's force).

2. The degree of precision of alignment needed increases, if magnets of small physical dimensions are used.  Example ...  0.005 of  1/2 inch is only about 1/4 of  0.005 of  1 7/8 inches.

3. The magnetic attraction possible between a given two magnets is typically greater than, is the repulsion between those same two magnets.  A near to balancing of  repelling force and attracting force of the two outer magnets,  each to the inner (shielding / shunting / force redirecting) magnet ( straight line 180 degree opposite vector),  is why the outer magnets can easily approach one another while the inner magnet is in place.  In CITFTA's build (post #4), the force neutralization is entirely dependent upon the rack and pinion, to create that near to balancing of attraction and repulsion.  That "near to balancing" is increased in the other design ( post #6 ).

4.  The ease of insertion and removal of the inner / force redirecting magnet, is also due to the creation of a near balance of attracting and repelling forces upon it (in the direction of its travel).  That "near to balancing is increased in the other design ( post #6 ).

5. The design in post # 6 is improved when it has a rack and pinion linkage of the outer magnets.

I'm not rooting for a build by you of the design in post #6. Though I hope to see one eventually.  I'm simply describing aspects of the functioning of these designs.

             Cool ?

   respectfully

@CITFTA

By adding only 1 additional magnet,  (not two, on the repelling side of the output magnet set only), you can increase the nearness to balance, of the insertion and removal of the shield magnet.

Or for an easy mod. of your build...
