Introduction
Dec. 14, 2003
Douglas Mann says he has successfully built a working Bowman Permanent Magnet motor. The approximate 1-foot-square device puts out 9 inch-pounds of torque, and can turn under load. With no load, the main shaft spins at 30 rpm. It does not accelerate to destruction but reaches a maximum speed and goes no faster. "You can run it as long as you want," he said. [See "issues"]
Purportedly, there are other working magnetic motors in operation in other places around the planet, but none are currently accessible for view by the world at large. This Bowman device successfully replicated by Douglas Mann may be the first to be made thus available, along with a complete set of instructions of how to replicate it.
One of Mann's friends his dismantled his motor and rebuilt it, and was able to successfully get it to work; and important milestone.
Mann used the instructions given at http://www.freeenergy.co.za/, among other places; but introduced some modifications of his own in order to get the device to work. His is a scaled up version: 8-inch main rotor rather than 4 inches.
I have been in communication with Doug Mann by phone, and he has related a complete set of instructions of how to build one of these devices. This page presents a complete set of instructions, given freely, with his permission.
Photos and video footage are pending but are not necessary for successful replication.
How the Bowman Magnetic Motor Works
Mann asserts that if a person understands the principle behind how the Bowman device works that the mechanics of replicating it become easier.
He said he had been working on this design for years but to no avail. At one point he decided he first needed to understand how magnets work. It was after that study that he was able to produce a working device.
He seems to have a developed gift to visualize what the magnetic fields are doing in four-dimensions (3D plus time). "I can see into these things," he said.
The fact (if it is as he says it is) that he has successfully built a working magnetic motor should be credential enough to his natural ability.
Depending on the manufacturer, the technique, and the magnet, the properties of magnets vary as much as 30% within even one batch. Some magnet distributors are particular about the uniformity of the magnets they sell, but even then there will be variation between magnets.
Hence, this magnetic motor is not something that can merely be described by blueprints alone. There are certain elements that must be "tuned" in assembling the components of each unit. Mann has identified what those elements are, eliminating the guesswork, and making it a matter of scientific method.
As we progress with this open sourcing project, there are a lot of variables that should be introduced and characterized, but first the task is to accomplish a simple replication.
Mann was hoping to come upon a way to use the entire magnetic force for motive power. However, this present design requires at least half of the magnet power to be used to counter-act one magnet with another, the remaining is tappable for power. He doesn't think more than that can be tapped. Perhaps someone will show him wrong someday, even as he is showing the present models of physics to be incorrect.

How Magnets Work
Understanding How Magnets Work in the Bowman Magnetic Motor
Don't Let the Magnets Smack Into Each Other
First, a word of caution. When working with magnets, it is very easy to accidentally have them smash into each other.
According to Mann, this must be avoided because the shock messes up the magnetic pole structure. If two magnets do smack together, you will need to re-measure them to see if their strength has been effected, and if so, how much, so you can regroup your magnets.
A Magnet's "Neutral Spot"
Mann has studied the shape that a magnetic field emits relative to the length versus width of the magnet. He has noted that the ratio of width to length of Bowman's magnets are consistently about 1 : 4.5.
Anything that is a ratio of 1:4 or less fits into classification called a "holding magnet." The defining characteristic is that as one moves along the magnet from North to South, the neutral point midway where the figure eight shape crosses is infinitesimally small.
But when a magnet goes beyond this ratio, that neutral point becomes a significant factor, stretching over a small length in the middle.
Much longer ratios begin to create a harmonics effect in which additional North-South polarities arise within the length of the magnet -- another magnet within the length of the magnet.
This ratio is a crucial element of the Bowman Magnetic Motor. All of the magnets are of the same length and width (ratio, can be scaled up or down), including the actuator magnet, in Mann's successful construction of Bowman's device.
Difference between Attraction and Repulsion
Mann said that repulsive forces work better close-up, and attractive forces work better at a distance, relatively speaking (we all know the overall strength of a magnet increase the closer the poles get to each other from adjacent magnets). The magnets emit a different concentration of force lines under attraction -- more spread out -- than they do under repulsion -- bunched together. Expect the neutral spot of a magnet to be offset from the physical center accordingly when one magnet is held 90º to the other. This becomes important in the proper placement of the actuator magnet in the "neutral zone" of the main rotor. The movement from this zone effects the function of the operation in a "tuning" sort of way. It is not a "hit or miss" scenario.
Magnetic Strength Proportional to Radii of Rotors
The magnets Mann purchased happened to be appropriate for the radius of of the device he constructed. He said that the stronger the magnets, the more distance will need to be placed between adjoining magnets or they will begin interfering with one another.
The highest power Neodymium magnets available today, [N...] , of the same size Mann used for this device, would call for the main rotor to be at least 18" in diameter.
On the other hand, magnets of a lower Gauss rating would require a smaller rotor diameter for optimal performance.
Nature of Magnetic Lines of Force
Just what the nature of the lines of force are is not required understanding for the Bowman motor. Mann agrees with Johnson and the patent office that accepted Johnson's patent that stated that the magnetic field produced by the permanent magnet is a form of nuclear energy. Mann said that is could be a high energy beta partial that can not escape the total internal reflection of the crystal lattice in the mass of the magnet. He also postulates that the present models of electromagnetic motor operation will need to be revisited by science when they see this magnetic motors in operation. The model that the AIAS has formed is more likely to be right. (&^& need ref)
Mann has studied Tom Bearden’s work and find that this type of process is common to nature. If Tom Bearden’s model is right then the motor will weight less under a load. Mann has not yet tested that hypothesis.
Theory of Magnetic Instability (TOMI)
Mann cites the following document as a seminal piece for its presentation of how magnetic forces work.
http://www.fortunecity.com/greenfield/bp/16/magnetic.htm
He highlighted in particular the following:
Tri-polar interaction:
In this configuration, notice:
1. The north pole of the horizontally presented magnet is further from the north pole of the left magnet, and this distancing isolates the interaction which normally occurs at closer range.
2. There is no longer an either/or relationship between the two magnets with regard to attraction or repulsion being operative in the system, but a simultaneous attraction/repulsion function operating between the two poles of the left magnet (stationary for this experiment) and the single south pole of the right magnet (non stationary).
3. The free magnet will move, not perpendicular but parallel with the lines of force. And it will always settle at a midpoint between the two poles of the stationary magnet on the left.
4. Contrary to the law of inverse squares, there will not be a magnetic lock between the two bodies, so no work is required to separate them.
This illustrates the angle at which he places his actuator magnet in relation to the magnets on the main rotor.
How the Bowman Magnetic Motor Works
How it Works
Here are some sketches Mann pulled together using a rudimentary drawing program. Sizes and shapes are not precise. The purpose is to illustrate the field interaction during rotation.
Douglas A. Mann's Sketches
Front face view
Net resistance is zero without actuator in place. (Target [after tuning]) Rotors spin freely as if no magnets exist.
* * * * * *
Introduction of Actuator magnet begins rotors in motion. Mann says some of the lines of magnetic force are drawn to the actuator, freeing up the lines of force from other magnets in vicinity, allowing magnets in QA1 to do work.
Note: When the Actuator is placed in the QA2 region, the rotation direction reverses.
Note: The optimal position for power output is for the actuator to be in the QR2 region in an attracting mode.
* * * * * *
Top view
Note labeling of the "Attracting rotor" and "Repulse Rotor"
* * * * * *
Actuator magnet must be placed equally repelling North, and attracting South poles of the power rotor magnets, so there is no load on the power rotor from the Actuator magnet fields. The effect of the Actuator will take up most of the flux from the passing power rotor magnets. This will reduce the force QR2 in figure 1. Then the force QA1 in figure 1 will cause rotation.
Important note relevant to strength of magnets and diameter of rotors: If the magnets are too strong, the fields will overlap and interfere. If they are too weak, the device will not self-start when the actuator is put in position.

Bowman Magnetic Motor Specs
Design Specifications
Mann said he used the dimensions of the Bowman motor given at http://www.freeenergy.co.za/ (complete URL is in link, not spelled out here because of its length [printout copies, try http://tinyurl.com/z5es]).
Drawings
Mann said these drawings are to scale, and that they are accurate with exception of the actuator. He changed some of the materials too. He took the below image, printed it, and enlarged it to 2x scale and used it as a blueprint. The image comes from http://www.icehouse.net/john1/peter.html
click for enlarged gif
Here are some additional drawings:
Note that as rotors turn, the meeting magnets will be aligning most closely on the horizontal plane exactly. This relationship is maintained between every magnet in turn. Without the actuator, a baseline target is a perfectly balanced "zero resistance" state, freely turning. See "tuning" instructions below.
Dimensions and Materials
According to the page Mann referenced, along with notes he conveyed by phone, here is a materials list. All materials, besides magnets, need to be non magnetic conducting. (See note: Use non-magnetic materials for rotors and body.)
NOTE: Where Mann used Delron, he would like to use Lexan, which is see-through, making for a better demo unit.
Scale: Do conversions based on main rotor diameter = 8 inches.
Rotor Magnets:
"NEO 32" [Neodymium 32; Gauss = ?]
Shape: cylindrical
Magnetism - polarity at ends.
Size: 3/8 inch diameter by 1.75 inch long. Mann said he went with this size because it is an "off-the-shelf" standard size. [Remember: Exact size is not as crucial as the 1 : 4.5 ratio of width to length.]
Quantity: Buy extra so you can select those of the closest actual Gauss.
Orientation: The magnets are situated lengthwise in the rotors, parallel with the shafts that hold the rotors.
Ends of magnets "were accordingly ground so as to pass close to opposing wheels with only a minute gap." Mann did not grind his Neodymiums, but selected the most uniform and used them as is.
Plating: Mann's magnets were Ni-plated (protects from corrosion of the Neodymium).
Actuator Magnet:
"NEO 32" [Neodymium 32; Gauss = ?]
Shape: rectangular box
Magnetism - on the flat side, with the 1/2" dimension holding the polarity.
Size: 1/2" x 3/8" x 1 3/8 "
Note: The ratio of dimensions is 3 x 4 x 11.
Note: The ratio of the length of the actuator magnet to the length of the rotor magnets is about 80%
Quantity: Buy extra in case the one is damaged.
Orientation: The south pole is closest to the rotor. The length of the magnet is parallel to the shaft of the rotor.
Plating: Ni-plated
Rotors:
The large rotor diameter is 8 inches, using Delron, milling the magnet holes so they nearly breach tangent, allowing close proximity to the actuator magnet.
The two small rotors diameters are 4 inches (to perimeter of magnet; extra material beyond is okay here), using Delron.
Thickness: not crucial, but should be adequate to (1) hold magnet securely, (2) allow for some adjustment of the 1.75" magnets parallel to shaft. Recommended: 1 inch.
Magnet holes are milled for tight fit of magnets so they can be adjusted with ~15 lbs pressure, but stay fast against the ~5 lb pressure when passing other magnets when installed and in motion. [Paper can be used as a temporary wedge. Glue could be used (but not until optimal position is determined by the timing procedure given below); or plastic synch screws could be fashioned].
Hole positions for magnets:
On small rotors: Exactly 0º, 90º, 180º, 270º; situated with outside edge of magnet as specified in the drawing. Material may extend beyond for strength in holding the magnet.
On large, main rotor: Exactly 0º, 45º, 90º, 135º, 180º, 225º 270º, 315º; situated with outside edge of magnet as specified in the drawing. Material should just end where the magnets end, so the actuator magnet can get close. A small amount of coverage (full enclosure) beyond the magnet would be okay for strength, but not more than 1.5 mm.
Note: If the actuator gets too close to the main rotor magnets, a "locking effect" comes into play, so some clearance is not only okay, but actually necessary.
Mann recommends that when machining the holes for the magnets that the bits turn at low speed. The higher speed tends to melt the plastic and leave a larger hole, through which the magnet does not fit snugly. In this case, you can use paper wedges to restore a snug fit.
Bearings
See: Bearings Considerations
Frame:
Device is mounted on a ~½-inch (thickness not crucial) Delron base.
Two upright sheets that hold the shafts are also made of Delron ~½-inch (thickness not crucial)
stainless steel bolts used to fasten the vertical support to the horizontal support.
Shafts: three parallel shafts
made of "3-16 stainless steel" [not sure of nomenclature representation in writing]
½-inch diameter.
center shaft needs extra length to attach to load (e.g. torque wrench)
position of small rotors on shaft needs to be adjustable to within 1/1000ths of an inch, and +/- ½ inch in relation to main rotor as shown in diagram.
Gears:
2:1 ratio spin rate of small rotors in relation to main rotor.
the center, large rotor spins in opposite direction to the two smaller rotors on either side.
Material: Mann had his gears made of steel. "They are far enough away from the magnets," he said.
Tolerance: very tight.
Configuration: standard "3rd gear / spur gears" so there is no clicking as the gear tines come together. using ½-inch belt.
Alternative: Not recommended until Mann's device has been replicated successfully as is.
Belt System - ½-inch belt.
Chain Sprocket
Actuator Holder:
Needs to have a plastic thumb screw to hold magnet as close as possible to main rotor, and be able to move +/- ½ inch in any direction relative to that position.
Misc tools needed
Torque wrench: typical, inexpensive, measures foot-lbs. Mann uses a 240 in-lb range wrench 1/4 drive. He said the force range that most will be working in is about 15 inch-lb max to zero.
Estimated Tolerances for Possible Variations
Some aspects are crucial, others have leeway, as indicated here:
Material Composition
Needs to be non-magnetic conducting.
Magnets: flexible to approximate Mann's working device.
Type may vary, as long as the Gauss is +/- ~20% of the Alnico 8s.
Size may be +/- ~20%, but should maintain the 1 : 4.5 ratio of width to length
rectangular v. cylindrical: may be interchangeable (though not with identical output, as rectangular magnets are stronger).
Mann calculated Bowman's rectangular magnets to be of dimension 5/8" x ½" x 2¼" (note: ½ : 2¼ gives the 1 : 4.5 ratio; while 5/8 : 2¼ gives a ratio of 1 : 3.6. Mann's tests show that the smaller face sets the ratio.)
He had two sets of magnets: Alnico, and NEO. He first unsuccessfully tried the Alnico magnets, but was able to get the NEO magnets to work.
Rotors: size: flexible
increase or decrease of size should approximate increase or decrease in Gauss of magnets relative to Mann's Alnico 8s.
main rotor needs to be 2x size of smaller rotors, which need to be the same diameter.
rotor positions relative to one another needs to be adhered to closely, proportionately.
Gearing: 2:1 precisely, no variations.
Shafts: thickness, length, and material not crucial except that the material should not be magnetically conducting.
Note: For purposes of successful replication, you would be best advised to stay as close as possible to Mann's design. At the same time, it would be good to implement means by which you can begin to introduce variations, once you achieve successful replication, in order to begin characterizing the device. See Points of Design Variation for Characterization and Optimization below.
Putting the Bowman Magnetic Motor Together
Manufacturing the Base, Vertical Support, and Rotors
See auxiliary tips: Cutting out pieces
See How to find the magnet radius on your rotors
Situating the Rotors Horizontally
Mann says the alignment of the rotors horizontally is important so as to get the right overlap of magnets. The magnets are not to be "face to face" when they come into horizontal position, but are to be offset by a little less than half the width of the magnet, looking from the front. There may be some leeway in this aspect.
This illustration is misleading, as there is no horizontal gap.
Magnets actually overlap a little less than 1/2 the width of the magnet.
* * * * *
The overlap shown in the above animation by Eric Vogels is what Mann says is the correct overlap.
Orientation of the Actuator
The orientation of the actuator in relation to horizontal should be about 35º (some leeway), and in relation to the main rotor tangent 90º.
In the illustration at the right (see enlarged view) Mann said the preferred position is somewhere between 1B and 2B, but closer to 1B, and at 90º to tangent of the main rotor.
Mann thinks the actuator magnet could be bigger than the magnets in the rotor, but he used the same size of magnet.
He says there is quite a bit of lee-way in the placement of the actuator. (I presume this means in the plane of alignment with the main rotor, 90º to tangent of the main rotor.)
The south pole is closest to the rotor. The length of the magnet is parallel to the shaft of the rotor.
Note: Illustration is not of Mann's
rotor or magnet. The actuator
magnets are rectangular, not cylindrical; and they run parallel
to the shaft
Timing
One of the keys to the motor's operation is a proper timing protocol whereby (1) the magnets are arranged correctly within each rotor front to back (parallel with shaft); and (2) the rotors are aligned correctly in relation to each other, front to back (parallel with the shaft); and (3) the actuator is aligned in relation to the main rotor. Perfect alignment is not required for function, but near approximation of perfection gives better results than a sloppy approximation.
Because of the way attraction works compared to repulsion (explained above), the attracting rotor will be situated a little further away than the the repelling rotor. Mann said in his case, the attracting rotor was about 60/1000 away from the main rotor, while the repelling rotor was about 20/1000 away from the main rotor. Bowman purportedly got his to within 5/1000.
A. Characterizing the Magnets for Uniform Distribution
The first thing Mann does before assembling the rotors is to run a rough gauss test on each magnet and then group them according to their strength.
He concurred with the following protocol. (Other methods can accomplish the same objective.) A gauss meter could be used instead.
Fix one magnet stationary -- the reference magnet.
Fix a small inert spacer over the magnet, e.g. 2 mm. Exact distance is not crucial, except that all magnets be measured with the same distance.
Devise a means of fastening a scale (weight) to a magnet to determine the force required to separate it from the reference magnet.
Record the reading for each magnet.
Order the magnets from strongest to weakest.
Group the magnets in two sets of four, and one set of eight, of relatively close magnetism.
Mann purchased 29 magnets and used 16.
B. Zero Out the Main Rotor in Relation to the Actuator
Note: a different magnet is used in the actuator position for the balancing of the rotor. A more narrow magnet, with poles at the end is preferable. A rotor magnet could be used.
Fix the actuator (substitute) magnet in place as close to the main rotor as possible.
One by one, move the magnets until they pass by the actuator without any resistance -- the N/S attraction/repulsion balancing each other out.
When done, the rotor should spin freely as though no magnets were present.
Note: Mann says "sometimes you will just need to turn a magnet 1/4 turn before it will match fields."
C. Put Actuator Magnet in Place and Mark Position.
Replace the temporary actuator with the actual actuator magnet, and position it very [(e.g. 2 mm) need exact specs] close to the rotor.
Orientation: The south pole is closest to the rotor. The length of the magnet is parallel to the shaft of the rotor.
Position the actuator magnet on its x,y horizontal axis so that the rotor turns freely as though no actuator were present.
Mark the position of the actuator to within 1/1000 and then remove it.
Mark the position of the main rotor to within 1/1000 in case it needs to be taken off and then put back on (not part of calibration, but take-down and set-up).
D. Calibrate Repelling Rotor
Calibrate each of the repel rotor magnets in relation to the main rotor so they yield the same torque reading on the torque wrench. Calibration is done by moving the repelling rotor magnets forward or backward, parallel to the shaft.
Remove the attract rotor, so only the repel and main rotors are in place.
Make sure the rotors are set on their gears so that the magnets are are exactly horizontally aligned when they come into juxtaposition on the horizontal plane that bisects the center of the rotors.
Position the first repel rotor magnet so it is evenly set on the rotor, with the same amount of overhang on the front and back of the rotor. (not essential, just practical and aesthetic)
Move the rotor out of position radially and then measure the torque required to bring that magnet past the point of repulsion.
Repeat three or four times to get a best average reading.
Using that reading as a standard, now adjust the remaining three magnets so they give the same reading on the torque meter.
Move the entire repel rotor along the plane of the shaft so it is as close as you can get it without the magnets actually touching.
Check again the torque reading, and record this number so you can repeat it for the attract rotor.
Mark the position of the main and repel rotors to within 1/1000ths, so when the repel rotor is removed to calibrate the attract rotor, it can be put back in place to within 1/1000ths of an inch.
Remove the repel rotor.
E. Calibrate Attract Rotor
Calibrate each of the attract rotor magnets in relation to the main rotor so they yield the same torque reading as was given for the repel rotor above.
Only the repel rotor in in place, with the main rotor. (Repel rotor is removed.)
Make sure the rotors are set on their gears so that the magnets are are exactly horizontally aligned when they come into juxtaposition on the horizontal plane that bisects the center of the rotors.
Repeat the steps given for the repel rotor calibration, except set each magnet to equal the standard derived from the repel calibration.
You may wish to position magnets so they are nominally centered on the rotor, rather than hanging more to one side or the other. (not essential, just practical for balance and aesthetics).
Mark the position of the main rotor and attract rotors to within 1/1000ths, so they can be removed and put back on without having to recalibrate.
F. Put all rotors in place: system should be balanced (zero)
After putting all three rotors in place as calibrated and marked, the rotors should now spin freely as if no magnets were in place. The only resistance should be that of the gears (or belt) and bearings. This is the milestone, which if reached, leaves just one step to realize the desired result: self-movement with addition of actuator.
G. Replace Actuator: Viola
Put the actuator into place as calibrated in step C.
The motor should begin spinning.

List is in process of being completed. Whichever engineer is the first to be able to visit Mann should document all of these specs.

Epilogue
Mann told me that he still gets a thrill when he watches the device begin to turn when he engages the actuator. "It's the strangest sensation to see it turning," with nothing more than just magnets positioned in the right way. He is still incredulous when he watches it, hardly believing what he is seeing.
As of our phone conversation, he hadn't even told his wife about the project yet, he is being very careful about its preservation.
He is grateful to be so close to a point where he can now share this with the world. His dyslexia makes it difficult for him to write, so he wants to be able to have one place on the Internet where everyone can go to get a complete set of instructions along with "Frequently Asked Questions." Images, still and video, are pending.
"Bowman has harnessed the law of action and reaction and put it into motion." Mann says it should be called the "free motive force."
"Electric waves could do the same thing," says Mann. "That may have been what Tesla was doing."
Bowman applied for a patent for his device, but the application was denied. It would be nice to get a hold of that application, though Mann seems to have been able to do pretty good without it.
