The invention creates an ELECTROMAGNETIC SWING MOTOR of general use and
whose main characteristic is to be constituted with only a movable piece.
This motor for your own constitution can acts as a compressor.
their characteristics of hermetic compressor, low cost, high income, reduced
size, possibility of double compression, immediate finds application in
an airtight cylinder C1, which is built with no magnetic materials.
the cylinder are electromagnets represented for two bobbins acted by two reels
B1 and B2, inside of the cylinder is the piston P1 constituted of a magnet with
N and S polarizations.
S1 and S2 are any types sensors, OPTICAL, MAGNETICALLY, HALL etc.
command electronic switching circuits who sending a pulse whenever the piston P1
arrives at the end of your course.
In a first instant, when is linked the current, the piston P1 is attracted inside the reel B2, when reaches at the end course, sensor S2 sends a pulse for the switching circuit that turns off B2 and turns on B1.
does with the piston is attracted in contrary sense inside of B1 and, in the
same way, when it reaches the end course, S1 give a pulse that had commanded off
B1 and it turns on B2.
cycle continues, the piston move back and forth, until the circuit current to be
In the illustration 2 below we see the complete motor outline,

current through the thyristors TR1 and TR2 that are commanded by circuit

shown outlines are merely explanatory, the construction admits several
improvements with the vast electromagnets technology available actually.
WITH MORE POWER AND INCOME.
illustration 3, a series of electromagnets 1, 3, 5 and 7 pull the
permanent magnets A, B, C and D for left, other series 2, 4, 6 and 8 pull for
way a better magnetic integration is gotten with better performance is obtained.
Compression cameras havenít valves V1, V2, V3 and V4 that command gases
entrances and exits, such and which valves of common compressors, can being of
can be linked compressing the same gas source, they work independent, and they
add their volumes, as shown below in the FIGURE 4.
operation is in two times, in a first time the piston moves for left, V1 close
and V3 opens up and the gas is pushed by the exit S of the tube. On this same
time, V2 opens and \ aspirates the gas for the common entrance E.
a second time, in that the piston moves for right, V1 open and aspirates the air
or gas for common entrance E, V2 closes and V4 opens up and the gas is pushed by
the exit S.
The compression camera of the left, EEC and the compression camera of the
right, CCD, act independent, as shown in figure 5.
They notably increase obtained final pressure.
in this configuration uses their two compression cameras with different cylinder
compression camera EEC has larger diameter than the camera CCD.
a first compression EEC aspirates air or gas for entrance E and injects directly
through his valve V3 in CCD having a first compression, in other words, the
gas that is already compressed inside CCD is compressed again, in a second
cycle, leaving for S.
should be noticed that the piston A has larger diameter than the pistons B, C
In cooling closed circuits lubrication uses special oils for each type of
the shown compressors described have the same configuration of pumps for
liquids, that is, they work in the same way, only that instead air or gas, they
work with liquids.
the configuration of pumps for liquids specifications can be included for
several usefulness and liquids types. Corrosive liquids, for instance, in
this case the internal part of the cylinder and the piston are covered for
non-corrosive materials specific for each liquid type.
As the system
works for magnetism, the pistons continue suffering the same attraction force
and repulsion of the electromagnets, there will be yes an income loss because
for more dies the film that to hide cylinder and piston, it had increased the
distance between the electromagnets and the permanent magnets.
great advantage of the invention is that the cycle, or pistons curse, is
completed independently whit the involved speeds.
fact has as consequence that the viscosity of the liquid pumped doesn't do to
interrupt the operation of the system. The pistons course is only inverted when
some of the pistons arrive indeed at the end of the course, and only in this
condition is that will act the sensor that commands the switching.
allows to the system several advantages, belonging one to them to allow pumping
liquids as thick as grease.
materials that recover the pistons and the cylinders can be selected to obtain a
minimum of attrition besides could spare lubrications.
pumping system with these characteristics can be useful for use without
contaminations, being a good example to pump human
the easy feeding of CC and high incomes obtained with special configurations,
they can serve as artificial heart.
system admits a lot of configurations that increase his income, as shown above
in the illustration 3,
other configurations can be implemented to increase the income.
The pistons can be manufactured with laminated materials of iron silicon, of low hysteresis or modern rare lands magnets can be used, the calls super magnets.
electromagnets can be implemented with rolling up and special threads that they
involve modern techniques of general knowledge.
rolling up shown in the outlines as including reels, that besides they involve
the cylinders can form only involving the cylinders, in the constructive reality
contains nuclei that are prolonged in the directions of the cylinders.
nuclei are shown in the illustration 7 as N1 and N2 and the rolling up of
the electromagnets, B1 and B2, recover part of the cylinder and the nuclei.
Electromagnets in reality are mounted in counter phase, that is, when one
is pulling the magnet the other is pushing the magnet. In other words, one
attracts and the other repels the piston.
SWING MOTOR FOR TOOLS.
configurations for use in tools, the piston is assembled in a stem that crosses
an or the two cylinders covers, this to impel most several machines, as fret
saws, hammers, tilts, industrial control, robotics, etc.
summary was presented, constructive details, outlines of the electronic part of
the switching and the sensor ones they are described in the invention deposited
