A basic schematic of the design.  The inverted "T" at the top just indicates tangent.  The stator magnet comes in from the right until the left end of the magnet reaches the tangent.  McNutt says the closer that magnet is to the rotor, the more torque it generates.  The idea is that the north end of the rotor magnets coming in counter clockwise are attracted to the south end of the stator magnet, and then are repelled out by the north end once they pass it.

This has to be the simplest free energy design I've ever encountered. I can't fathom anything being any simpler than this. Does it work?

According to David McNutt, who contacted me yesterday to tell met about this, "it works". And he's willing to open source the design. If it turns out to verify as a functional design, we (PES Network, Inc. and McNutt) have an agreement for sharing any revenues that might come from this (traffic, plans, kits, completed units, etc).

He built it a decade ago using ½-inch Styrofoam, a pencil for the shaft, and some 1/4x1/4-inch rod magnets (neodymium-iron-boron) he had kicking around from a game called mag-neticks. He used a hand drill to make equally-spaced holes around the perimeter of the approximately 4.5 to 5-inch diameter Styrofoam piece. He said it is important to not have the rotor magnet any further apart than the diameter of the magnet; and on the other extreme, the rotor magnets must not be so close they touch.

The stator is comprised of a rod magnet of dimensions ¼" by 1-inch. He brings it into position by hand, coming in vertically along the tangent line, as the arrow on the right indicates.

"Then keeping the drive rod … at [N] side toward the disk and at a 90 degree angle and in line so it is at the outside edge (but not touching). The closer you place the drive magnet the faster, and stronger the torque."

At the time he built this 8-10 years ago, he was living with a friend, Jerry Elswick, and wanted to prove that a generator could be made using just the power of magnets.

McNutt said he never got more than 3-4 revolutions before things fell apart, as the set-up was very crude. If the stator magnet got too close to the rotor, it pulled the magnet out.

I called Jerry, who said he's been friends with David for a couple of decades; and yes he remembered the motor. He thought it had run maybe 200 revolutions for maybe 2-3 minutes. Jerry said David had been working on the idea for years and had it all worked out on paper, and claimed he could build a simple proof of concept design; so Jerry gave him free run of his garage. David got some magnets from Wal-Mart "from some toy", and in maybe 2-3 days he had built the device.

Jerry called back saying that his wife, Betty, also remembers seeing it run. I talked to her on the phone as well. "I remember it was a pretty big thing back then," she said. She thinks it was more like 5-6 years ago. "They were working on it over a few weekends."

David said that after the Styrofoam version that he then fabricated a similar unit using square magnets, a bar magnet, wood and hot glue. He said this one started spinning so fast in the first fraction of a second that one of the magnets flew out from centripetal force and scared the dog.

That's all he's ever done with it, being a bit paranoid.

Now he would like to see it resurrected and scaled to replace the primary driver in power plants. The reason he called me was to see if I knew anyone who could replicate this.

"I have changed to an arc magnet instead of the rod for the better field distribution in my next design. (But with no help funding for the machining it's been in limbo for a long time.)"

He agrees with me that a magnet motor does not violate core laws of physics but merely harnesses some yet-to-be-understood principle of nature. He has a theory about that.

It's simple enough to validate easily.

Wouldn't that be a hoot if this really worked! So close, and yet so far away – for all these decades. "Why didn't someone think of it sooner?" will be the most frequently asked question, followed by, "Why didn't McNutt do something with it before now?" Better late than never.

I talked him into letting us use his name in the motor name because it is so apropos for this "crackpot" stigma field.

Is it real? Let me know what you find, you replicators out there.

If it's a working design, I'd love to be able to announce it to the Earth Transformation conference I'm speaking at on Friday evening. We may be able to webcast that live. The more replications we can refer to, the better. This one could be just the ticket for breaking the logjam on free energy technologies.

Buying drill press in the morning and can start on next model.

OVERVIEW of work done to date

This design was made as a proof of concept with what was available at the time. It only shows the motion and thereby a weak effect is created.This is by no means the last in the design. To correct for the magnetic flux density on the rotor, substitute a Diamagnetic to obtain the consistency for the rotor. While this works it is not an effective design because of the lack of torque. This is overcome in the later versions.



Saving for drill press and then I can start making a model.

I will use the same setup but four bar magnets to run it(stator).and four arc magnets for the rotor. Drawing it up today.



Thanks Clanzer for the work btw all my fault for the lack of drawing.

Started making my ver.

Hi Sterling

This most basic setup is what most people try when first playing with magnets. I have tried multiple magnets on a rotor in the same config as shown before and sorry to say it does not work.

I do not see how this will work, If he was holding the stator magnet and it was not static, then we are back to the hand movement doing the work and no free lunch.

Probably got a rotor knocking around that is suitable to show what I mean, but I think it will be a waste of time. Will see if I can get time later.

Note: This is a nice-looking piece of work; however, CLaNZeR's spacing between rotor magnets is not as suggested by McNutt, who said they should not be any further apart than 1/2 the diameter of the rotor magnet, and they should not be touching. CLaNZeR's rotor magnets are at least 1 diameter distance apart. -- SilverThunder 10:52, 8 January 2010 (PST)

note by David:

Close, the reason it equalizes is because of the short stator magnet. Using that rotor I would estimate a 6" rod would be required to get rotation. If you notice the rotor stops at the S pole of the closest magnet segment(because there are three magnets each is a segment with separate fields.) The stator must have a length that places the center of the magnet in line with the incoming rotor magnet. Using the mid point as the attraction source should compensate for the magnet spacing.


The rotor spacing is great now just need to get more compression from the stator but the model im starting may make it more obvious what happens when the field is in line. to get rotation the flux field between the stator and the rotor must be compressed by moving much closer as long as the south pole stays out of range it will repeat.

Seems odd that one said it broke after a few revolutions and the other said it ran at 200 RPM for several minutes. Maybe they built several. What is described has never worked for me. Maybe I just do not understand.

Response: No one said 200 rpm. They said "maybe 200 rotations". -- SilverThunder

My main account is not working yet as this was a fast posting, so I made a temp contact email with so I could post.

No, it was 200 turns or revolutions he guessed. He was estimating turns and the time he played with it.

The math for that estimation is faulty because at that calculated RPM the centrifugal force alone would have made the magnets come out of the foam. This was a friend who saw it run for a concept not a full practical model.

The magnetic field must be uniform around the rotor (the more uniform, the better the function of the rotor). The field determines the length of the driving magnet "stator" and such it's S pole MUST be out of the reach of the field from the rotor or it will equalize and therefore stop the motion; so the best way to set it is so that when the rotor magnet comes in range of the magnetic field of the "stator" it MUST be past the mid point of the stator or the field can find a balance and therefore stops the turn/motion as can be seen by simply placing a small magnet at different center-points on a longer magnet. The reversing direction of said field must not be close to the rotor. You can extend the field by a longer stator or simply adding an iron rod/bar (magnetic material) to the end of the stator this will alter the field to allow a one way direction.

And yes I have made many changes to provide a much stronger and more stable magnetic field effect, that first model was only to show the concept; not a final product (to clarify).

And thank you for the question. I hope I answered you appropriately.

Thanks; David

Basic Theory of the McNutt Magnet Motor (MMM)

by David McNutt co-written with Anne Olivia
Jan. 8, 2010

Basic science precepts teach that opposites attract and like poles repel in magnetic fields.

My theory extends this understanding of the characteristics of the magnetic fields' uses. In other words, if we are using a permanent magnet for it's magnetic field effect or, if you like, this shape of the field can be manipulated.

With a round permanent magnet you have a N and a S pole that are directly opposite each other. Thus, the magnetic field effect resembles the shape of the magnet. In order to achieve a differnt magnetic field, a magnet is used to incororate the desired effect. For further clarify, a rotor needs to have a circular magnetic field. To achieve the desired effect the external or exposed part of the magnet should be N, with the S being the internal pole.

For safety and efficacy reasons, it is preferable that these magnets are enclosed, due to the risk of the strong fields moving the magnet and effecting the balance of the rotor. Also it reduces the chance of a damaged magnet being thrown out of the rotor assembly, possibly injuring or damaging the mechanics of the motor or anyone within range. The magnets can shatter similar to schrapnel.

The "stator" magnet drives the rotor pushing by using the same N pole of as the outside of the rotor magnets.

The critical difference in this design is that the stator magnetic field effect is accomplished by assuring that the S pole is distant enought to have no effect of the rotor magnets. This maintains the pushing action of basic magnetic theory. It also results in the continous rotation of the motor. This reaction immediately spins the rotor at a high rate. In time, inertia will somewhat accelerate the rotation. However, this is relatively insignificant.

It is extremely important that the axle or shaft in the motor does not generate friction, thus resulting in instability of rotation or drag. This does not contradict any known science of magnetics. It simply manipulates the magnetic fields in a consistent manner, as well as lending it to new uses.
