Title: Smudge’s Halbach motor

“”Here is a paper that I have just compiled dealing with a modified Halbach array that offers the potential for a free-running magnet motor.  My simulations in FEMM for a pair of linear arrays show that a linear motor utilizing permanent magnets could work.  The question now is would a pair of circular arrays also offer this possibility for a rotary version.  I do not have the capability of building such a device so I offer it to anyone out there to give it a try.  The advantage over other motors that have evolved by trail and error experimentation is that its working principle is clear, hence it is more likely to be accepted by the scientific establishment.  And finessing the design for best performance is a doddle.

Smudge is on the right track, but would advise to leave the idea alone as it can be weaponized quite easily.

Sir
Perhaps you are in the wrong forum ?


Please read mission statement for membership?


Definitely the wrong thread ( builders topic)!


When something as passive as magnetism
Gets your thumbs down?
Oxygen ,water , and gravity can’t be far behind ... ( all will play a part eventually)


“Too dangerous for humanity??”




Please contribute towards our efforts to find solutions for our planet and it’s many needs
or start Another topic elsewhere to address your concerns
 Everything may be fine at your house !
 I can assure you that is not the case globally .


And getting worse with every passing moment!

Im going to clarify just for the sake of it.  The images posted here reminded me of a design i came up with around 10-15 years ago based on info I came upon initially on this forum.  The design wasnt a purely passive design as i dont believe those ever work, although, i believe you can obtain an assist from a permanent magnet.  The info has been presented here many times just not put together.  The problem was it was too easy to weaponize so i left it alone and moved on and pursed other viable methods that couldn't be used to hurt anyone.  So far i believe there are three. Now i dont know where the "too dangerous for humanity" thing came from.  I just think that ultimately smudge is going reach the same conclusion. I'll stick to posting when my work is complete and replicated.

ALL I CAN TELL YOU IS MAGNETISM IS FORCE IN SWIRLING MOTION.
SO THE PERMANENT MAGNET NEEDS TO BE SPINNING IN YOUR DESIGN.

THE BEST I HAVE SEEN. ALL ONE NEEDS TO DO IS MOUNT THE MOVING NIBS ON A WHEEL.
AND MAKE SURE IT SPIN ON ITS CENTRAL AXIS.

The neo. magnets must be forced into the magnetic field at the start of the
ramp.  Input = output

Wrong!!  Magnetic fields are not conservative, although in most experiments they seem to be.  In the modified Halbach array the magnetic pole passes through field regions where it gets a driving force, the magnet gets accelerated.  So along the array it sees a series of force impulses.  The field at each impulse has the same magnitude, there is not an ever increasing magnitude.  The energy to enter that array is determined by the field magnitude at the first impulse point.  The total energy obtained is determined by the length of the array and the number of impulses, so a long array yields maximum energy gain far exceeding the energy needed to force the magnet into the array.  The pole movement through each impulse is somewhat like electron movement around a single turn in a transformer secondary.  Have more turns and you get more induced voltage even though the circular E field remains the same magnitude.  The multiple impulses act like multiple turns while the H or B fields have the same magnitude.

A toroid with arc magnets that opened a circular slit toward the center to permit an axled traveler to attach to a rotor arm would work. The traveler needs to be a siamese disk. NS/SN.

The general problem with simulations is that simulations are based on known laws of physics and these laws don't allow things like 'overunity'.
If there is such thing like a magnet motor it must be based on 'exotic' effects which are NOT included in the models of any simulation software.

There is only one way for verification: build and test it.

I strongly doubt that ANY construction consisting only of passive elements (permanent magnets) is able to show 'overunity'.

I've already started the design on my build. Anyone else?

I have enough magnets to start a build but would prefer to hear from Smudge on his further musings and thoughts on my questions before starting and investing in more magnets.

I did try simulating a single circular array with the working side facing inwards, but that did not show the same effect as a linear array.  In that arrangement the change from linear to circular took away the wanted effect.  However I am still looking into this simpler arrangement to see whether I can get it to work.

In your alternate linear version of the Halbach array your FEMM results were improved by using a permeable material such as Fe inplace of certain magnets. Could you do the same for the circular array using square magnets and wedge shaped transitions between either a few of the PMs or all? There's also the option of 'squaring the circle' by using a polygon of linear segments, but it might add complexity to the radial magnet, or not.

I see Smudge is on the task
And also some very interesting comments
On his methodology with simulations !


And how he does this !


Very cool .


I suspect an update as mentioned in link

Sorry Smudge

I was refering to the type of magnet array presented by seychelles, just prior to my post,

THE BEST I HAVE SEEN. ALL ONE NEEDS TO DO IS MOUNT THE MOVING NIBS ON A WHEEL.
AND MAKE SURE IT SPIN ON ITS CENTRAL AXIS.

I don't know how the Halbach array will behave.
