If you’re like me and have a spare pc fan laying round Then it’s continuously a just right concept to connect a neodymium Magnet to each and every certainly one of its blades and use a more strong magnet to repel them in order that the fan spins without end and accordingly produces a limitless quantity of free power Sounds too excellent to be proper, proper? Good on this video let’s play around with this notorious magnet computer fan and the so referred to as Bedini motor to find out how so much free vigour we can actually produce Let’s get started First off this hooked up for this magnet laptop fan is fake the light bulb is actually powered by using one channel of my lab bench energy provide while the other channel provides a voltage of two.7V for the fan in order that it may well slowly spin with out raising an excessive amount of suspicion given that it is unimaginable to speed up the fan exclusively via the magnetic repulsion in view that the magnetic attraction happens a fraction of a 2d later and sincerely counteracts the rotation however now not simplest that if we solder a pink LED to three one-of-a-kind pc enthusiasts and Spin them we are able to see that two LEDs keep wholly darkish and just one lights up decently right here for an awfully quick period of time The rationale is the driver circuit of the fans which might be all somewhat extraordinary but have been all by no means supposed to be used as a generator circuits this is the reason the first fan truly outputs nothing the second one outputs 1/2 wave of a sine wave with a peak voltage of 1.5V And the 1/3 One outputs two rectified halves of a sine wave with the peak voltage of 2V And even though we use the fan with the best output vigor the LEDs light intensity would most effective equal an energy of around zero.01W without doubt now not adequate to vigor a 21W light bulb.
So all in all of the magnet computer fan is bullshit next is the Bedini motor whose circuit schematic appears most of the time anything like this As a power source it typically aspects a 12V battery that via the magic of the circuit provides free power and accordingly either bills up a 2nd battery or lights up neon bulbs Now all the obligatory component for it is pretty common, and accordingly not a crisis collectively besides the 2 coils which symbolize the motor stator section of the circuit For that, I to begin with needed to do away with the label of a pc fan with a view to put off the circlip that holds the rotor in situation After casting off it as well I unsolder the four wires from the circuits and pulled off this stator with driver circuit out of the case then I heated up the connector pins of the stator to dispose of the motive force circuits and persisted via unsoldering the two coil wires from two connector pins What we want finally are the four wires protruding from the stator to which we ought to solder 4 extension wires Which we can then at ease in place with sizzling glue and then redirect out of the pc fan case whilst the stator will get put in its historical place Now by way of measuring the resistance between the four wires we must get two pairs with the resistance of about 21O Which signify the two coil pairs After marking certainly one of them it was time to create the circuits.
Which due to its simplicity right here best took around 5 minutes As a vigor supply i take advantage of my lab bench vigour deliver Set to 12V and as the to be charged as battery I used the super capacitor best difficulty was that the circuit failed to wish to begin on its possess A small Spin for the pan used to be imperative to get it going and as you can find the capacitor did get charged up even as the circuits do around 2W on the input to be able to calculate the efficiency right here i stopped the circuit, discharged the capacitor established it again at the same time additionally establishing a stopwatch after round 8 minutes the capacitor reached the voltage of 1V With its ability of 22F this equals an output vigor of 11Ws For the enter power right here We with no trouble have got to multiply the enter energy of around 2W with the time the charging required which equals an enegy of 956Ws so the circuit does characteristic a total effectivity of 1.15% hold in mind that when dealing with free energy right here we strive for an efficiency of above 100% and this is 1% but for final test let’s unsolder the capacitor and instead let’s add a neon bulb to the output of the circuits as one can find right here the bulb lights up brighter on the outputs than it does on the input which means that there needs to be free vigor worried is what men and women would argue now, but that can be bullshit The rationale for this can also be determined when we analyze the circuits First off we spin the router in order that a constructive voltage is precipitated into the bottom part coil Which then pushes current by means of the bottom of the transistor This opens the collector center direction and as a result current can drift by way of the other coil Which for that reason builds up of Magnetic fields and continues relocating the rotor due to this an terrible voltage is precipitated into the opposite coil and as a result a poor voltage is utilized to the base Which closes the Collector emitter path here it gets fascinating.
The saved energy of the coil in its magnetic fields gets pushed into the neon bulb Which results in a small voltage spike, and accordingly a brief second in which it lights up Afterwards though the bottom facet coil will get once more triggered with an optimistic voltage and the cycle repeats all over again So all in all this is easily a crude boost converter that surely no longer uses the sort of factor as free power I mean from a logical aspect of view you give enter energy have enormous quantities of resistances voltage drops and power losses on your circuits and nonetheless assume more power on the output than on the enter that is not sensible, however, i will give the circuit this.
It’s a pretty first-rate fan driver Anyway, I am hoping you loved watching this video. If this is the case don’t forget to love share and subscribe stay creative and I will see you next time.
