Ekobots - Perpetual motion motor by jsirgado

Perpetual motion motor, magnetic shield engine.
Holiday, Brazil, sunny day...
Let's build a perpetual motion engine.
Different of all perpetual motion engines that you can find in the internet,THIS ONE DOES NOT WORK, yet. But that is just a little detail. ;-P
You can try another arrangement for the magnets, who knows...
I know all physics and thermodynamics laws,
and know this object goes against me, but I did it, why not?
All you need:
5x bearing (13 x 5 x 4 mm)
2 for the shield frame, 2 for motor frame, 1 for 18 teeth gear;
2x screw (60 x 4 mm) for motor frame;
1x screw (20 x 4 mm) for 18 teeth gear;
1x threaded rod (120 x 4mm) or screw full threaded for shaft;
10x cylinder magnetic (6 x 5 mm) for the rotor;
12x rectangular magnetic (10 x 10 x 3 mm) for the stator;
2x mild steel plate (20 x 20 x 2.5 mm) for the magnetic shield,
or an old hard disk to remove and cut the magnetic shielding
or other material with properties to block the magnetic field.
some nuts and washers for (4 mm) screw;

Assembly sequence:
1 - Clean all parts;
2 - Use small washers or pieces of plastic pipe to adjust the position of all parts
in the shaft;
3 - Fix the magnets in the rotor, you can use glue or adhesive tape;
4 - Fix the magnets in the stator, you can use glue or adhesive tape;
5 - Fix the rotor near the center of the shaft with 2 nuts and 2 washers and make
sure it is really well fixed;
6 - Fix 2 bearings in the shield frame;
7 - Fix 2 bearings in the shield motor;
8 - Fix 1 bearing in the 18 teeth gear;
9 - Use 2 pieces of filament 3mm to adjust the 24 teeth shield gear over the shield
frame and glue all;
10 - Insert the 2 parts of the shield frame in the shaft with the rotor in the center and
glue them;
11 - Glue the mild steel plates inside the shield frame;
12 - Mount the motor frame with the rotor and the shield in it using screws, washers
and nuts;
13 - Mount the 18 teeth gear in the motor frame using the small screw, nut and washer;
14 - Fix the 24 teeth rotor gear in the shaft with 2 nuts and 2 washers;
How it should work:
Same as electric motor, you have magnetic fields in the rotor and in the stator.
But the main idea is use the magnetic shield to "turn off" the power,
like in the electric motor the shield cuts the rotor magnetic field,
just at determined positions.
Because we have 2 full rings of magnets the shield can rotate almost "free",
just some diamagnetic effect force.
In the correct position the rotor will be attracted and in all others positions repulsed.
The shield prevent the stop of the rotor when facing the opposite magnetic field in the stator.
The inertial movement will do the job, until the next position of attraction.
Maybe you cannot see, but:
There are a lot of variables, like size, number and position of magnets,
to keep rotor and shield spinning "free", and we can add some improvements
like Hallbach arrangement, curved shield, active magnetically shield, etc.
See the images for the magnets arrangement.

Use small washers or plastic pipe to adjust the rotor position.
That is all Folks!
