I found these two pdf files on the original motor... not English. I translated with Google.. pdfs not by builder of original build.. someone discussing the motor and if it is real or not. 03/04/2010 Terni. to gastone The motor magnetic Rovella Titian is very interesting and running on you tube, find it on the internet beating engine magnetic Rovella The structural simplicity bordering on impossible, as you see. It seems an outlet for a ride, but logically it seems a self sustaining due to reaction of the two electromagnets that draw power from the torus and appropriately if the toss in sync; the crime occurs when the bull magnet (eg. right) energizes the right reel that feeds the left and to the turn enter into reaction with the magnet bull left, and it's just that this action becomes effective because it calls into play the forces of a permanent magnet a Electric. It is therefore necessary that the current flowing in the coils of reaction, when the reed is in right side looking maneuver, opens, and the torus dex approaches him in the face almost abandoned after the bolt. (5 °) There's a moment that lasts a very short opening and is when fc magnetic ( reed) is close to the bolt in a moment that the induced voltage has begun to decrease, then, if the induced voltage observed with the oscilloscope, you should noticed a big surge with dash vertically thereto, each other takes place in the other left reel generating flow in 2 opposition (thrust) see below: The reed switch is normally closed off by the action of the magnet. It seems to me to be replicated for the amusement of the great padreterni physics. I ask him for permission to reply and clarification on the magnetite or more polarized toroidal ferrite which has much more weight and has the supermagnets advantage of being circular, with a large air gap of 10 mm can trigger the phenomenon of attraction and repulsion at the same time and there is the effect of energy Kinetic comes into play, under the nut to the bearing is what that law for the air gap and the forces at play, FLOWS AND CURRENTS. The calibration point is the moment of opening and closing the magnetic relay energized at the minimum distance of the toroids (approximately 3 ° before and after 3 ° remains interdict) is a operating point to be determined. The 2 LED light for the presence of voltage induced on the coils and this occurs at a particular time (when the 3 right coil is energized by the magnet, which comes from the opposite side of the F.C. Magnetic beyond the right-bolt, start the flow of the magnet to invest head of the bolt, that being an inert element attracts the toroid, but the variation of flow creates a tension coil in the form of alternating almost rectangular, which has its maximum value when the bolt head has the toroid completely above it and ends to have the voltage pulse when the periphery of the toroid is located next to the magnetic relay but still has 50 .. 60% of influence on the coil. In the meantime the left bolt has been the current that is given by right reel, which is generating an impulse, in the subject to this, the head of the bolt is magnetization sign equal to that of the torus and rejects significantly only towards the end and in motion, as it is a reaction between 2 magnetic polarity equal, then is to exist a driving torque which supports car with the increase of speeds up to overcome the friction and beyond. This phenomenon will last over time if the reed work because overvoltage peak occurs at the time in which the magnet generator passive the effect of attraction has ended and another magnet but still provides the impetus as it absorbs more current to its polarity. The two LEDs turn on when, only when the bolt heads are in the area action of the torus. Then almost simultaneously. the phenomenon of induction is value of about 1.5 to 3 volts LED initiation of pulse, and this voltage can be directly connect 2 LEDs. Very little is the magnetic flux that interlinks with the iron of the bolts, but effective create a suitable polarity to the attraction and repulsion sufficiently to win the friction. It is estimated a constant speed of about 100-150 revolutions / 1 'by counting the flashes of the led and dividing by 2 (light up every half a turn). I think that the use of toroids is more crucial because of the large supermagnets that possess surface and by the fact that the flow captured by the coils of the relays continues even after that the axis of conjunction of the toroids has exceeded widely the heads of the bolts. And for this reason, besides the mechanical one has used the screen aluminum is on the parts not necessary that on the basis of the 3 bolts. On this gem of Ravella must be said that we must be very careful to replicate it, not invent anything, observe the geometry as well as one sees them, the measures are all reported to the reality of his hands and what we see on home video, not 4 going off the measurements, because the flows of the torus play a decisive role, as well as the air gap around 10 mm. And perhaps there may be some piece of shielding plate hidden by the blue band in a suitable position in both toroids, I can not see them are thin, you must end the very true replication deform the outflow. ½ relationship with a model, not working for geometries fake, and perhaps lack of mu-metal screen, it was possible to determine the waveform that is leads without involving the reed. When does the reed will notice the strong surge that exceeds more than twice the rated and then go up with the changes. Expect to see a nearly rectangular waveform with some very rounded and only near the end surge in the descending part. To check the polarity of the coils need only do an experiment: 1. Excite the bolt head with a magnet placed on a N bolt Quickly remove the magnet from the bolt by pulling it upwards If you have placed on the bolt you will see a calamitina N that is thrown away. Otherwise, reverse the polarity of the coil or you can enter in so inverted them toroid if the maneuver is simpler but better than not if there is a sheet of mu-metal flow as deforming At first it was thought that the elastic band had a function of mechanical support since the torus is supported by evil only 2 bolts instead would retain the thin plate shielding. 2. 3. 4. 5. 5 6 . 7 The cost of the magnets is 5 euros, and wat the reed and slightly higher, bearing costs 7 euros, the coils must autocostruirle. His address is: tiziano.rovella @ tin.it Personally I say it could be a big hoax, but first I have to sincerare because now I am sure that the laws of thermodynamics in these cases does not mean anything. It is the motor's magnetic Perendev in concept but other version is. The architects of the movement are actually two coils that react with The rotating toroids. (but creates an electromotive force collects passively with its presence, drive torque of attraction, the other draws power and creates a reaction repulsive much stronger than the attraction at least 2 or 3 times, depends on the type of steel, which is why turning in that direction). The coach, I think it has a specialization in robotics and should raise it. To increase the speed should be done with the powder cores of electromagnets ferrite not in solid bolt, the head should be treated with a mold to form 8 the salient pole much more effective as a reaction; also the rotating part would be from tiziano better care because he had to use an elastic band to support 2 toroids better (maybe it's camouflage for the mu-metal), the current conditions do not There are magnets that would form a slightly arched pairs ideal for the rotation, however, could work with lathe at least the side surfaces heads of bolts. Since the rotor tends to remain in equilibrium 90 ° from the junction of 2 rolls or bolts must be given the first start, that is, prepare it, and then everything happens. It's like nell'altalena the child and how the wheel Orffyreus. The question on the magnetite is polarized: the north-south face is identical in both, or is opposite to have the reaction of the other coil? (Maybe even if you put the donuts in the same direction polarization, only to act on the senses of the coils and you're done) First of all I would like an answer on the possibility of replication of the design that, among those inspected so far, it seems to me the most interesting and original inexpensive in all directions. A great toy to keep at home near the billboard "thermodynamic Mass K.O. from electrodynamics "is just the electricity that you win well gravitation see the lifter and one of my toys eighteen years 50 '. Thanks in advance. No answer, but it does nothing it will be annoyed if I have time I set about it, but with supermagnets rectangular cross-drilled much more effective and iron filings with resin on the coil. (Careful with those guys might not work and it takes a long gap weight) This engine unlike the other models have a bivalent behavior: if put the reed (magnetic switches for elevators) on the right is realized the trend clockwise viewed from above, the trend is done vice versa counterclockwise. The ease with which the reversibility is realized, both right and left, but always with the torus from beyond the head of the bolt makes sense on a constant deformation of the flow for the phase attractive to make the electromagnet relative receptive of the flow and therefore current generator for the other electromagnet; 9 and this can happen if the flow is diverted to the opposite side of the mu-metal bolts for each toroid. By dint of watching the movie, for a moment, you can see the plate that goes under the circular screens of aluminum towards the central axis, seems to be 0.35 mm. This is very significant for our fraud and indicates that it can exist at example no battery inserted in the circuit because the functioning of the electromagnets is only fair versa pulsating current that flows in both the windings. The fact that it gives more meaning to this toy is generated by the reversibility function of electromagnets (left) (right) that together can become a generator, the other receiver of energy and vice versa. But in this function, which depends on the position of the reed, is played as the principle of operation: it should be noted that the function determining the acceleration is more the receiver coil that creates the same polarity of the ring ferrite determining the repulsion very effective because the magnetization is in a point of the magnetic characteristic of which is many times greater than the attraction depending on the relative permeability of the iron with the induction. I can say that there is no fraud in this beautiful toy building: bravo six Rovella n'a bbestia.
