Joe Flynn's Parallel Path Magnetic Technology

By Tim Harwood.

There is a common opinion that some kind of exotic new physics will be required in order to significantly improve the efficiency of electrical motors, while many doubt such a thing is even scientifically possible.

The credit for this ground breaking research goes to Joe Flynn, who has been engaged in magnetic flux research for over 25 years now. His work is long standing, comprehensive, and in later years, well funded. It is reported $7m has been spent to date, with over $lm alone developing a revolutionary high performance magnetic motor. His equipment is validated and apparently already in mass production for select customers.

Since many lines of research have been formulated and explored by Joe Flynn, the following article presents only a brief summary of some of his best apparatus, but is nonetheless sufficient to convey the basic ideas, and provide a framework within which one can undertake experiments.

Figure 1

Figure 1 is taken from Joe Flynn's US patent 6,246,561 awarded on June 12, 2001 and filed on July 31, 1998. It explains a simple magnetic force multiplication experiment, which forms the basis for the Flynn magnetic art. If the windings on either side of the central magnet, which are normally connected in series, are properly pulsed, the field of the permanent magnet in the center, will be diverted to the opposite side of the core flux path provided. Or in alternative language, the side of the core that is pulsed, is demagnetized, relative to the field of the permanent magnet used in the apparatus. This is elementary textbook physics anyone can understand.

So what is surprising about this apparently simple apparatus, is that the armature on the side of the flux core, will contain 1.75 times more units of magnetic force, than could be manifested by the electrical input to the apparatus alone. Since the ability to arbitrarily move force from one point to another is the basis for motion or work, however simplistic, we therefore have a basis for a system that can be developed for practical technological purposes.

Expressed in alternative language, we also have the capability to engineer a time varying magnetic field, without the need for moving parts, which will allow development of systems that output electrical energy. Both capabilities are highly desirable, and offer substantial opportunity for technical development.

Expanding upon this basic experiment, there is a second simple and logical improvement in layout illustrated in Figure 2, which should be obvious, but has been shown not to be the case. In this instance, the pulse is centrally located and a dual flux field layout employed, which both demagnetizes the core relative to one magnet, and magnetizes it relative to the other. Since the two actions are complementary, the input required to manifest the flux switching effect is halved, therefore doubling efficiency.'

Figure 2

It should be noted thatwhile the efficiency is doubled, the absolute output may not be significantly improved. This is because the major weakness of this effect and technology is flux saturation of the core, with values depending upon the specific properties of the B-H curve of the core material employed, limiting absolute output of both layouts the same.

The previous statements are not required to be taken on trust, and simple experiments have been proposed by Joe Flynn, such that anyone can validate this ef&d for themselves. Figure 3 is a simple experiment taken from the Flynn website, that can be used to validate the principals put forward in this article.

Figure 3

An even simpler non electrical flux experiment was proposed by GM in the Parallel Path egroup. My apparatus is illustrated in Figure 4. It is no more than magnets and steel staple strips, bought from a local hardware store for a total of under $20. The Parallel Path effect can be replicated with identical apparatus, at only a slight increase in cost and complexity, with the addition of a simple 12v polarity reversible power supply, such as those commonly sold to power computer speakers, among other household applications.

One of the aspects of the Flyrm technology people find most difficult to understand, is how you can have a device that delivers 3.47 times more units of magnetic force than is electrically inputted, yet not violate accepted principals of text book physics.I feel this apparent puzzle can not be better explained than by reference to Joe Flynn's own analysis of the experiment presented in Figure 3.

 Since the Parallel Path System produced 3.47 times more force than the conventional system, with the same electrical input, it appears to violate conservation this is only true when observed from a tradional view point.

So the system is 347 % efficient, in terms of delivered magnetic force compared to net electrical input, yet still conforms to the accepted physical principals of field conversation, by being only 69 % efficient, in terms of the fields present in the system. However surprising this result may appear, the analysis presented is in outline correct with the difference between fields present in the system, and net electrical input, being the important concept presented.

In order to optimise flux cores, an appreciation of the physics that underlies the transfer of flux within a core is required. The normal magnetization curve, or B -H curve, is a mathematical relationship between applied field intensity H, and resultant flux density manifested in the core B. It varies according to core material, and the curve will shift, if there is a starting magnetism within the core, such as that provided by the field of a permanent magnet. If the start magnetism is excessive, the core is saturated, and will not properly respond to the applied force H. A simple B-H curve is illustrated in Figure 5.

Hysteresis is a delay between applied magnetic force H, and resultant flux density B, that again varies according to material type. It also manifests as a delay between the termination of force H, and the manifestation of flux density B. So, the system will not turn on instantly, and will not turn off instantly, in simple terms. This is because the magnetic memory of the core, mean s a flux vector remains within it, even when the application of magnetic force H has been terminated. If we apply a reversed force H to the core, the basic B-H curve is now expanded as in Figure 6, with the memory effect also illustrated.

In order to return to the initial switched state, the remnance magnetism must now be overcome, hence input once in operation, will be greater than that required for the very first pulse. The area within the hysteresis curve gives a rough estimate for the amount of wasted energy, and along with other conventional sources of losses resultant in flux transfer within a core, is what reduces the efficiency of flux cores from maximum values of 2, or 4, down to values such as 1.75 or 3.47 typically.

Although numerous practical applications abound for this effect electric motor design remains the most outstanding opportunity. To this extent, again a few simple images, should be sufficient to explain how the basic flux switching apparatus, can be turned into a highly efficient electrical motor.

The first motor shown in Figure 7 is one I have proposed to validate the flux switching effect at a most basic level. It illustrates the point made in the Flynn patent, that the annature of the core can be removed and replaced with a motor flux path. This first motor is not claimed to be highly ewicient but it helps one to understand how the transition from simple flux core to motor takes place.

 

The next motor shown in Figure 8 is again taken directly from the Flynn patent, and illustrates the next intermediate step to motor design. The fields of the permanent mapets are alternatively switched from one side of the surrounding flux cores to the other, alternately interacting with N and S poles on the rotor, imparting motion to the central rotor shaft.

Figure 8

With proper financial support, and the facilities to have Metglas(r) cores custom moulded, Joe Flynn was able to develop improved motor apparatus, shown in Figure 9. No detailed performance numbers have been released for this motor, whose precise characteristics remain proprietary to Joe Flynn at this time. But the optimisation is so advanced, it is stated to posses exotic performance properties, such as cool ambient operation and reduced current draw.
