Description

Radial electromagnetic induction motor and Variable on induced solid copper with grooves.

The present invention, as expressed in the statement of this specification refers to an engine electromagnetic radial and variable induction on an armature of solid copper that along its perimeter has practiced short and long longitudinal grooves.

Designed for industrial use and designed to offer numerous and remarkable advantages over electric motors that are known in the current art, whether current DC or AC.

In the present invention, the stator, the rotor, the cover and the covers, form a single set so that function as a magnetic circuit and effectively leverage the field strength generated by the stator coils.

The arrangement of the stator coils and the Exclusive rotor design is designed so that the power transmitted to the shaft is considerably higher than contemplated by the current technique and, nevertheless, reduce the energy consumption at sufficient levels so that your operation is possible by other means, other than a power line, for example by batteries electric.

Background of the invention

- Numerous and different types of DC and AC motors. The difference among them lies in the constructive form and type of power applied to the rotor and stator.

Among the disadvantages they present can be to appreciate:

- The weight and dimensions they present with their construction in relation to the power they can provide, not makes them fit to be installed as a driving force in media mobile phones

- The complexity of its design and subsequent execution

- The limit in revolutions per minute remains set by the speed with which the current of feed or by the number of pairs of the magnetic poles that Compose the inductor part.

However there is a direct drive motor which has the axes of the stator coils perpendicular to the rotor shaft, forming a crown. Although this engine offers considerable advantages over traditional engines that they fit in the previous section, it has the disadvantage of not make good use of the magnetic fields generated, by the arrangement of the coils that make up the stator, distributed in groups of parallel, vertical and perpendicular to the axis forming a crown, and on the other hand the rotor, whose construction does not allow to get the currents induced that are achieved with the application of the new proposal.

In accordance with the attached designs this invention consists of a cover (Figs. 1 and 2) constituted by a hollow copper cylinder, which allows to accommodate the rotor (Figs. 5 and 6), the stator solenoid coils (Figs. 3 and 4) and serves as support to the side covers (Figs. 9 and 10). The wall (a) of this hollow cylinder is such that it allows to enclose the assembly of stator solenoid coils (Fig. 3 and 4) in each of the through holes (c) of the wall that have been made in the same for this purpose, and whose diameter allows to accommodate without gaps the  solenoid coils (Figs. 3 and 4) that it will contain. In the example that we are examining, the number of coils and holes is preferably 30.

The thickness of the wall (a) of the roof (Figs. 1 and 2) it will be the smallest possible, enough to accommodate the coils of the stator (Figs. 3 and 4) and give solidity to the whole and yet allow the rotor with its axis (Figs. 5 and 6) to have the highest possible diameter to achieve maximum power. Also the air gap, that is the air chamber between the interior of the cover and the outer surface of the rotor disk, must be as small as possible, and that there is no rubbing between the roof (Figs. 1 and 2) and rotor (Figs. 5 and 6) in order to avoid losses as much as possible of energy

In addition, radio channels have to be practiced at the outer edge of the wall (a) of the roof (Fig 1 and 2) at along the projection of its outer circumference, to allow output of the wires of each solenoid that composes the stator (Figs. 3 and 4) in order to provide them with the electric power, which they need  to generate the magnetic fields.

The stator, (Fig 3 and 4) which in this example of embodiment consists of thirty solenoid coils introduced in each of the holes made (c) in the cover wall (a) prepared for this purpose.

The arrangement of the solenoids that make up the Stator (Figs. 3 and 4) is such that all its axes are presented parallel to the rotor shaft (Fig. 5), while the turns of all of them are arranged perpendicularly to said axis.

The planes of the north and south poles of the different solenoids are faced respectively with each of the two side covers (Figs. 9 and 10). Field strength coming out of the north pole coincides with the cover on this side, while the field strength that enters through the south pole, After embracing the rotor, it meets the opposite cover.

The field that produces each solenoid coil of the stator (Figs. 3 and 4) hugs a portion of the rotor (Figs. 5 and 6), giving rise to the induced currents in the blades (Figs. 7 and 8) which coincide with the section of the space that said coil occupies inductor This phenomenon occurs simultaneously in all coils that make up the stator (Figs. 3 and 4) and gives rise to a field variable internal and radial magnetic of more or less intensity than hugs the rotor (Figs. 5 and 6) along its entire circumference and that depends on two factors, on the one hand the major or minor magnetic field strength, dependent on the power to each coil that you want to supply, and on the other hand the form that adopts the magnetic field, in its pole parabolic path north to the south pole hugging the rotor (Fig. 5 and 6).

It is interesting to note that between the crests of magnetic field that appear between two adjacent solenoids exists a magnetic valley that facilitates the recovery of electrons from the blades (Figs. 7 and 8) of the rotor (Figs. 5 and 6) when found in it and that were diverted to the axis by the action of the magnetic field crest produced by the solenoid previous.

The electronic thrust towards the shaft rotates the rotor (Figs. 5 and 6), as a result of the set of pairs of force appearing on the blades (Figs. 7 and 8) of the rotor disk (Figs. 5 and 6), while the recovered electrons return to be pushed towards the shaft when they meet again with the next magnetic crest of the next solenoid, causing a new push.

This process would continue to increase speed of the rotor (Figs. 5 and 6) and therefore the power, so it is necessary to provide it with electronic control circuits to adjust its benefits to our needs, in each case.

In addition, the electronic thrust is performed simultaneously in all the blades (Figs. 7 and 8) found subjected to the influence of magnetic crests, and why this thrust is made towards the axis, equal force pairs appear magnitude, which rotate the rotor (Figs. 5 and 6).

The rotor (Figs. 5 and 6) is formed in this example of realization by a disk with three hundred slots and a shaft, which form a single solid piece of copper.

The shaft can be made, with a diameter that be the third part of the disc. The power or speed that is want to get depends on the length of the slots Longitudinals that are practiced along the circumference of the  rotor (Figs. 5 and 6). The slots are of two kinds, long (d) or short (e).

In this example the sixty long slots (d) whose length reaches the axis, avoid circular currents surface along the length of the circumference of the same and therefore it is possible to take advantage of all the pushing power that supply the retained electrons within the limits of each blade (Figs. 7 and 8) and that have been influenced by induction of the magnetic field. Also in this case, the two hundred and forty short slots (e) allow you to create one hundred and twenty pairs of forces additional. In other words, the rotor is formed by three hundred blades between long (d) and short (e), which provide one hundred and fifty pairs of forces of equal intensity acting in turn

The object of the side covers, (Figs. 9 and 10) is to better concentrate the magnetic fields produced by the stator (Figs. 3 and 4) to form a closed magnetic circuit.

And finally the bearings with bearings (Figs. 11 and 12) provide the rotor (Figs. 5 and 6) with a clamping means and the possibility to rotate on its axis and transmit the power mechanical rotation of the device to be operated.

The device object of this invention is build as seen by the pieces that fit between yes and they are fixed to a base (Fig. 19) to join the assembly.

The solenoid coils (Figs. 3 and 4) are introduced in the holes (c) presented by the cover (Figs. 1 and 2) and they take the threads out through the grooves in their edge (f), for later feeding.

It is inserted into the roof gap (Fig. 1) the rotor (Figs. 5 and 6), and then the covers are mounted (Figs. 9 and 10), to close the circuit.

The shaft, which protrudes on both sides of the caps (Figs. 9 and 10) are introduced into the two bases containing the bearings (Figs. 13 and 14).

Finally the cover is fixed (Figs. 1 and 2) and the bearing supports (Figs. 11 and 12) to a base machining (Figs. 13 and 14) fixed by screws in order to form a only set (Fig. 15).

The wires of all solenoid coils (Figs. 3 and 4) are braided individually, and then as a set of bundles, in order to obtain two power terminals and supply the regulated electric current that will produce the magnetic fields

Finally, the supports of the rotor shaft bearings that hold everything by existing screws for this purpose.

This engine allows to vary its characteristics so just by varying the dimensions of it in scale. The power maximum is limited by the resistance of copper to fusion or for reasons of convenience in design.
