Magnetic Overly-efficient Variable Engine Rotary
In the following drawing, the big circle is a rotating permanent magnet. The
little circles are the electromagnet.
While the rotating magnet approaches the electromagnet, the pulse coil is not energized and therefore the permanent magnet is attracted the non-energized metal core of the electromagnet.
When the rotating magnet is approximately centered on the electromagnet, current is applied to the pulse coil to produce a magnetic field strong enough to release the magnetic grip of permanent magnet.
The electromagnet may have a some force of the same polarity,
the rotating magnet may be repelled and continues in its rotation. There are five areas of interest in magnetic attraction and repulsion; where magnets are attracted to each other, where magnets are repulsed by each other, where there is no attraction or repulsion equal to Q, where there is an attaction to non-energized metal equal to Q+K, where there is a repulsion of Q-K between the objects, One may be able to go as far as Q-K when charging the pulse coils.
The repulsive force of two permanent magnets exists even if there is very little opposing force. It is interesting that when using much smaller magnets with much smaller surface field gauss there is still a fierce opposition to a larger magnet of same polarity. There is very little difference between causing the release of the magnetic grip and creating a very slight repulsive force. It may be that you need very little extra energy to release the grip, plus cause a slight repulsion. You may be able to go as far as the amount needed to charge the pulse coils equal to the magnitude of the attraction of a magnet to metal to gain torque and efficiency.
Brushes and other mechanical connection devices can be used for correct timing. An electronic distribution system can be used to create the exact waveform needed for timing and tuning.
As the permanent magnet moves farther from the electromagnet, less current is needed since the strength of the attraction varies with the distance between them. If timed and tuned properly, the time it takes for the permanent magnets to move out of the attraction field can be the amount of time needed for the residual magnetic force to flush away from the core of the electromagnet.
When the rotating permanent magnets reach the basic attraction distance past the electromagnet the magnetic force of the electromagnet is null.
The energy needed to create enough force in the electromagnet to release the magnetic grip of the permanent magnet is less than the force of the attraction of the permanent magnet to the non-energized metal core of the electromagnet. If the timing can be such that the dissipation of the residue magnetism in the cores matches the retreat of the permanent magnets away from the electromagnet; that would be good.
Concept: Kore - Very Efficient Motor/Generator:
The Kore Rotary Engine is configured in a squirrel cage configuration.
Attach the electromagnets to a support structure in a circular array. Attach the permanent magnets in a circular array to a wheel connected to a shaft. Arrange the permanent magnets so they line up with the electromagnets as elements on the support structure. Combine the electromagnets support structure and the permanent magnets wheel so the permanent magnets and electromagnets form elements lined up properly. The wheel is supported by a shaft supported by bearings or other means.
Arrange an appropriate number of elements in a circle to form a single wheel of elements. This wheel has six elements. The permanent magnets rotate as the wheel rotates and the electromagnets remain in position by their support.
When the rotating magnet is approximately centered on the electromagnet, current is applied to the pulse coils to produce a magnetic field strong enough to release the magnetic grip of permanent magnet.
In this configuration, the Basic Attraction Distance is measured from the side of the magnet at the point where noticeable attraction begins. This distance is where, if you are holding a permanent magnet in one hand and a piece of metal in the other, you can feel the attraction beginning to pull them together.
Using the permanent magnets with their faces parallel to the faces of the non-energized core of the electromagnet, rotate the permanent magnets towards the edge of the core on the path of its rotation. When the permanent magnets get to the basic attraction distance, the permanent magnets are attracted to the non-magnetized core of the electromagnet.
When the permanent magnets have been attracted the maximum and are centered or nearly centered to the electromagnets, a pulse of currentis is applied to the coils.
As the permanent magnets move farther from the electromagnet, less current is needed since the strength of the attraction varies with the distance between them. If timed and tuned properly, it may be possible for the time it takes for the permanent magnets to move out of the attraction field can be the amount of time needed for the residual magnetic force to flush away from the core of the electromagnet. When the rotating permanent magnets reach the basic attraction distance past the electromagnet the magnetic force of the electromagnet is null.
The energy needed to create enough force in the electromagnets to release the magnetic grip of the permanent magnet is less than the force of the attraction of the permanent magnets to the non-energized metal cores of the electromagnets.
There may be an advantage to having all the inside permanent
magnets as close as they can get. Here is one wheel with eight elements pushed
together to the center as close as possible. This creates a very strong
magnetic force applied to the shaft.
It may be that you want to have the opposing permanent magnets with opposite polarities slightly offset from each other to replicate the negative and positive poles of a complete magnetic field.
In the following the elements are offset, opposing faces have the different polarity.
The energy gained by manipulating the interaction of magnetic fields within a coil may be of significant value and comes with little loss. Create a wheel with just an array of Permanent magnets and spin them around an output coil. Experiment with different polarities and different offsets. Measure the current produced.
The outputs of the output coils have different polarities since they are affected by the different polarities of the permanent magnets. Time the system and/or manipulate the system output with circuits to create alternating current. Reversing the polarity of every other wheel would give equal amounts of positive and negative current.
The output coils can be created in many ways. A simple way would be to have a continuous winding where the second winding overlaps the first completed winding by continuing on top of and over the first complete winding.
On the other hand, It may be that the output coils have to have a gap between the start and finish of the coil to complete the coil function more efficiently. It may be of more advantage to have a number of individual coils.
The permanent magnets can be shaped in any size and
dimension to maximize the efficiency. The permanent magnets can
be modified from very thick magnets to very thin magnetic plates. The
cores can be shaped from thin at the middle to thick
at the ends. The height, thickness and width and all other specifications of
the all the permanent magnets, cores, coils, electronics, bearings,
frequencies, revolutions per minute, wheels, supports and all parts of the
system should be determined by the resulting efficiency.
There may be an advantage from using an unequal number of permanent magnets compared
From Advanced Lab, Mediawiki: http://www.advancedlab.org/mediawiki/index.php?title=Hysteresis
"The typical but exaggerated hysteresis behavior of a ferromagnetic material is shown in the figure below, where the magnetic induction B is plotted vs. the magnetic field intensity H, which is directly proportional to the current in the surrounding coil. The horizontal axis could equally well be labeled ``I" instead of ``H". The "0" is the non-magnetized or demagnetized state (B=0, I=0) which can be reached by applying an alternating current and slowly reducing its amplitude to zero. As the current increases from the demagnetized state, the B value lags behind what one might expect and follows the curve to (a') and toward saturation at (a). With large variations in I, the behavior follows a major loop (abcdefa...); while for small variations in I, the behavior follows a minor loop (a'b'c'd'e'f'a'...) or (a'b'a'...) if the current I never becomes negative. Certain points of a hysteresis loop have names: Br is the remanent value at I = 0 after the material is saturated at (a.) Hc is the coercive field or the coercivity ( i.e. the H or I required to reduce B to zero)."
Using electronic control this system can be operated between a' and b'. This would eliminate the hysteresis loss since it is operating above the loss at 0 to b'.
The above shows a detailed analysis of the hysteresis loop. First, they show the standard “S” hysteresis loop that is commonly found (a, b, c, d, e, f, a). The current starts a 0, increases to a, which is saturation of the material, then passes through b and c to reach d as an equal negative current is applied. It then passes through e and f to return to a, as another positive current is applied. This repeats in the loop.
This also shows a loop defined by a’ b’ c’ d’ e’ f’ a’. This is a loop that is of lesser value so as not to go to saturation. Notice how it is of an elliptical shape and not like an “S”. That is good.
But most important, notice the third loop – a’ b’ a’. As the article states “or (a'b'a'...) if the current "I" never becomes negative”
The loop moves perfectly from a’ to b’, exactly what this system needs. While the system is in operation, the a’ is the pulse point, where the pulse happens and the permanent magnets move away.; b’ is the attraction phase, where the permanent magnet is attracted to the non-magnetized core. If timed right, and a little assistance from electronics, this system can run bouncing back and forth between a’ and b’. This system can ride above the hysteresis loss, staying charged, between a' and b'.
While the system is running, the cores have to get to a point that replicates uncharged metal so the permanent magnets will still be attracted to the cores significantly. This is can be done by using permanent magnets as the cores of the electromagnets - equal in force to the difference between 0 and b’. Thereby shifting the 0 point relative to the permanent magnets and the cores up to b’, while at the same time maintaining the complete hysteresis loop relative to itself.
The distribution and timing of the pulses can be accomplished in any appropriate way. An electronics bundle can be constructed to gather the output and distribute it at the appropriate times to the appropriate places. The electrical bundle contains all electronics needed for control, timing, and distribution of electricity, and all other electrical and electronic needs.
Specific variations and changes in the application of the current to the electromagnets are used to maximize the output. For example, one can introduce an electric pulse in the form of a sine wave, saw tooth wave, stair step wave, square wave, etc. The waveform of the applied current maximizes the attraction and release related to the system. It may be necessary to hold this pulse waveform to strict values. A pulse at the end of the release phase of opposite polarity may be needed to flush the core fast enough to make the timing of the pulses viable. If indeed the system can be timed to use the natural dissipation in the core, this would be of an advantage. There is an increase in torque by applying a current more than just enough to release the magnetic grip.
A wiring harness connects all relevant parts with appropriate current. Connectors on an electrical bundle can connect to any peripheral devices for any use.
A mechanical brush assembly could be used to apply the pulse to the pulse coils at the appropriate times.
The device can be attached to any connecting and/or assist devices such as gears, chains, pulleys, belts, flywheels, hydraulic systems, transmissions or any other connecting device or devices to maximize energy output for use in any application needing energy.
I would like to think this could be overunity and lead to free energy, I am not convinced of that, but this is interesting enough to look into.
