Mechanically reverse polarity of magnets in motor idea (images)

[MagnaProp]

...The rotation gears (blue & pink) engage and flip the magnet 180 degrees...

Just saw your design. I always like to look at new magnet motor ideas so thanks for posting it. My concern is how this flip occurs. Sounds like it would fight the flip since in order to flip it has to pull the smaller magnet away from the larger one. I don't see how a gear ratio helps with that.

A couple of of points:

Depending on the environment, it can take energy to flip the polarity.

Also, it might be possible to demagnetise and re-magnetise (reversed) on the fly. But this will require some energy.

Yes it is a magnet polarity switcher.  It doesnt do full flips though. Just enough to have more N up and more S down and switch.

In the thread most of it is in great detail.  Spent a LOT of time making all the parts by hand. Well, jig saw using laminate blades for precision cuts, drill and dremel.

It is asymmetric where the rotor has even number of mags alternating N S N S and odd number of stators. The idea was to only switch 1 stator at a time while all the others are in locked push pull mode.  The big issue was that I had originally designed it for 8 rotor mags and seven stators. For some reason i went with 10 rotor and 9 stators.  But I didnt factor in that more created a problem that I didnt foresee till after.  I didnt make modifications to the amount of distance to throw 1 switch at a time.  I was getting double contact on stators. While one was finishing switching, another began. In early tests there was enough force to turn 1 stator at a time, not 2.

I was just sooo frustrated after all that work that while I was in the midst of my plan to commit harry-carry,  I just put it down and made the idea open source.


But over the years I have some things I would change. Will reopen that thread and post them as I have time.


On of the big issues is too much open space creating weak field interactions. I think I have that problem solved.

Anyway, Ill start posting the newer ideas as i get time to think it all together.

If interested, go through the thread and watch the vids.  For hand made, the thing was a gem. Every latch worked perfectly.

Excellent work Mags.

I looked at your topic and watched the videos. You're a true craftsman!

Thanks for sharing

Thanks Luc

A 3D printer would be key these days.
