Electric motors are a desirable alternative to internal
combustion engines widely used in Industry, Agriculture, Domestic
Appliances, Aerospace and Transport.. Applications for the GEMINI
are widespread; trains, fork lifts, cars, escalators, elevators, pumps,
aircraft, air-conditioning, refrigeration, washing machines,
dishwashers, ovens, microwaves etc. literally dozens of implements in
daily use.
As
new discoveries in the properties of permanent magnets, and the
direction of their flux lines is understood, it may be that small
magnetic motors, which run on the magnetism and configuration of
the permanent magnets will be used to trickle charge batteries to
supply the power for automobiles and domestic use.
Announcing the discovery of a new magnet
phenomenon, we have all learnt that like magnetic poles repel each
other, and that unlike magnetic poles attract each other. This new
discovery caught my interest as like many inventors from around the
world the thought of making a magnetic motor using permanent magnets,
and no electricity or batteries has taken up a lot of my time. I do not
use those horrible words, " perpetual motion ", as the source
would be a known force, namely magnetism. The discovery in 2002, that
there is a particular configuration where two unlike magnetic poles will
repel each other, and not the usual attract each other, was made by Mr.
Washington Lucero, originally from Colombia South America, but who has
lived in New York, U.S.A. for the last 23 years. He described a simple
experiment to prove his discovery.
" You require two 1" (25mm)
diameter or square magnet, with 0.250" (6mm) thickness with the
magnetic flux through the thickness. The experiment works better if
neodymium magnets are used. On a shiny smooth flat surface, put one
magnet with the "North" pole facing up. Either side of this
magnet, and about 6" from the magnet put a pencil. Position a flat
ruler across the top of the pencils, over the magnet. Place the second
magnet on top of either end of the ruler with the "South" pole
facing down. There should be a gap between the bottom magnet and the
ruler to allow it to move, Fig.1.

Slowly move the top magnet towards the
bottom magnet. You would expect that as opposite magnetic poles attract,
the two magnets would come together, but the opposite occurs, the bottom
magnet is repelled. Why? Sure if you stop the bottom magnet from moving,
there is a point that it will be attracted to the top magnet. In case
you are thinking it is the ruler stopping the bottom magnet from
flipping, the same experiment works if you place the top magnet on a
rubber, no pencils or ruler, and move it towards the bottom magnet, it
will initially repel the bottom magnet.

FIG. 2
Fig. 2. shows the magnetic flux lines of
the magnets placed in this position. It is now hoped this new discovery
with unconventional magnetic properties will get inventors and those who
can think outside the square to come up with a practical application for
this discovery. Another unconventional discovery is the Halbach array,
which is a special arrangements of permanent magnets that increases the
magnetic flux field on one side of the device while reducing the
magnetic flux field to near zero on the other side.

FIG.3.
This effect was first discovered by
Mallinson in 1973, but it was not until the 1980s, that the late Klaus
Halbach, a physicist at Lawrence Berkeley National Laboratory, invented
the Halbach array to focus accelerator particle beams. Other
applications raging from a refrigerator magnet, industrial applications
include the brushless AC motor and magnetic couplings, while high-tech
applications such as the wiggler magnets are used in particle
accelerators, free electron lasers and the Inductrack maglev, which is a
levitating train that requires no power to levitate, only electrical
power to move forward. Another recent discovery is the movement of
magnetic fluxes in the conventional electric motor. This was explained
in the presentation by Mr. Ettridge at the
Coil Winding Expo, held at Berlin, Germany. Mr.
Ettridge demonstrated that the experts had got it wrong with the
accepted magnetic flux line within the conventional electric motor. His
reasoning and with the use of pictures clearly proved his point, it
followed this reasoning.

Ettridge.

poles facing each other.

Fig.4. The magnetic flux paths and an explanation of
why this is correct.
The explanation goes like this, the magnetic flux
lines in fig.1 are the normally accepted magnetic flux lines that you
will find in text books and computer modelling. They are wrong, and the
reasoning is simple to follow. Mr.Ettridge said the lines of magnetic
force are as illustrated in Fig.2 , He refers to the picture fig.3 which
has two North Magnetic Poles facing each other, separated by metal
laminated strips, this has been sprinkled with magnet grindings ( tiny
magnets ) It is clear to see that the flux lines radiate from the
centre, the two North magnetic poles do not make one big North magnetic
pole. With this knowledge, we apply it to Fig.4. The three energized
coil poles, are numbered 1-2-3, the permanent magnets in the stator are
through magnetized, and have a North magnetic pole on on side, and a
South magnetic pole on the adjacent side. The arrows in the centre show
the direction the rotor is turning. In energized coil no.1, it has to be
a North magnetic pole to be repelled by the North pole permanent magnet.
If it is a North magnetic pole on the outside of the energized coil, it
has to be a South magnetic pole on the other side of the energized coil
( the centre of the rotor). If we look at energized coil no.2. the
outside magnetic pole has to be a North magnetic pole, to be attracted
to the South magnetic pole in the permanent magnet in the stator. Again
if it is a North magnetic pole on the outside of the energized coil, it
has to be a South magnetic at the centre. From
the picture fig.3. we know that the magnetic flux lines do not treat the
two South magnetic poles at the centre of the rotor as one big South
magnetic pole, but in fact the flux line will radiate from between the
two South poles, and therefore travel as shown by the arrows. So the
North magnetic poles in the rotor are as close as practicable to the
permanent magnets in the stator, but the South magnetic poles at the
centre of the rotor have to travel through a large air gap, before they
react with the permanent magnets in the stator, and would add very
little torque to the motor. This explains why the Gemini Electric Motor
achieves so much better torque, for a given amount of electric current,
simply because each time the energized coil is energized, it only
has an air gap both sides of the energized coil, between the permanent
magnets in the stator, not the one in the conventional electric motor.
