Seems that you stumbled on something I have been working towards. I didn't know about the joule thief and basically my set up was a small generator hooked into a transformer that powered a motor, but a small motor running a generator seems to be more power dense for practical purposes. Fantastic mate!
Love it Dr. Smith. I can see Nichola Tesla laughing the same way when he was doing his original poly-phase experiments. Something to consider. When the field is created, it is created from the inside out. When it collapses, it also collapses from the inside out. My understanding of this is kind of like a push and push again. Never a push then pull.
Off topic but I recently found a permanent magnet converted alternator in a scrap pile! I was very surprised to find that the rotor has 7 MAGNET POLES! this means that they are all arranged with the same polarity. I had never seen this arrangement before. In quick testing it has a pretty good output between 2 phases (need to make a 3 phase bridge rectifier still). I also hooked it up to an e-bike controller with a dulled lawn mower blade on the shaft (for resistance) and it had some incredible torque with medium-low rpm. One thing I don’t love about it is the fact that the whole body of the alternator is magnetic, I expect this is caused by the magnet poles not canceling each other out.. I’m curious if adding more magnets with alternating poles would increase the top rpm when used as a motor, and if this would cancel out the magnetic flux that is distributed to the body of the alternator… and what would happen if the magnets I add to the rotor have a different strength than the original 7 (which are quite strong). Anyways, I just got excited about finding this baby (for free) and wonder if anyone has any insight about this style of PM alternator. Cheers!
Oh and from my research the only example of a similar design was from Missouri Wind and Solar, so I’m sure that’s the company who built it. Haven’t really found any other examples yet of this design online.
I think you are brilliant and your sessions and ideas are mind blowing. Could you do a video on how to go to the next step from generating power I to something usable for a shed perhaps?
cool, add a diode from the collector and an electrolytic cap to ground and tap off the point where they meet and youll get much more voltage from the joule thief....:) cheers matey...
wow what did the 6 on top (magnets) come from? looks like the epoxy or glue pulled some of the plated metal to protect the neodymium iron boron mixture off of it, (seen this many times on my break aways when I grab the armature magnet out of a hard drive) and I found that the rusty bits if you scrap them together still have quite a bit of magnetism to the dust *as in it generates its own magnetic field) also reminds me that I have not passed on my home made magnets that I used crushed neodymium magnet powder mixed in epoxy and left to sit on a solid magnet while the epoxy sets up, generating a single sided magnet (the other side is spikes of the other side pole being what is inside them and the outside of the spike is the opposing pole rather than it being uniform to the side laying against that magnet it is laying on top of) I can show you in discord the photos I took of it from a cross section of broken material with the light shining through it to make it evident what one is looking at :) I remember your talking about redirecting magnetic flow through a piece of iron and then moving the other end around when discussion on magnets in your video and how to use them. and thought of a way to make a system to control direction of magnet material from a single uniform flat side basically (slide the magnet across a triangular block on one side, and it changes which face of the other 3 sides that it comes out basically splitting side one so half is directed to side two and the other half of side one directs to side 3 :)
Hear is a thought to mull over... One may make a mechanically commutated reluctance motor. In its simplist form.... Wind an electromagnet on a single stator bolt. The electromagnet is in series with a double throw type switch that is made closed by two wires making contact with one of 6 rotor bolts. The closed switch allows current to flow through the electromagnet putting torque on the rotor bolt. As the coil is energized, it pulls the the rotor bolt closer and closer untill it breaks contact with the double throw switch when the rotor bolt is directly over the stator bolt. The rotor's momentum keeps it spinning untill the next rotor bolt closes the double throw switch. Simple motor with No electronic components, and no magnets. Just iron bolts and copper wire for a single coil, and for the double throw switch. If you want to make it generate, put two coils on the electromagnet. Have the primary wound in one direction, and the secondary wound in the opposite direction. Place a diode on one of the secondary's output. The diode should alliw current to flow out of the secondary coil and through the diode. Then place a capacitor or battery or load to the diode's output and the other side of the secondary. Finally spin the motor backward from how it motors to make it generate. Description of how this reluctance generator workes. A rotor bolt makes contact the switch when it is directly over the stator bolt. The coil is energized and creates a magnetic field that pulls on the rotor bolt taking away angular momentum and converting it to potential energy in the magnetic field. Then after a certain amount of rotation the rotor bolt breaks contact with the double throw switch, and current stopes flowing in the primary resulting in the magnetic field collapsing. And dumping virtually all the energy stored in the magnetic field into the secondary coil where current flows through the diode to charge a capacitor, a battery, or disipate in some other load. Because the secondary coil circuit absorbes the energy from the colapsing magnetic field, very little inductive spike happens across the primary coil and and switch that may be protected by a very very very small capacitor that further minimizes the voltage spike across the switch on the primary side. Minus efficency losses, the secondary coil circuit collects the energy that was used in creating the magnetic field, and the work put into the magetic field through moving a piece of iron away from the electromagnet.
So, what if you slap this serpentine coil generator/motor on to a bike, one side of the wheel is a motor and the other is the generator for recharging as you ride. That brings me too this next thought, if it can get the torque maybe two of these motors can be put on the driving axle of a VW beetle, or one on each wheel near the drum breaks for an simple classic VW hybrid conversion while maintaining the integrity of the original IC engine. Or it could be an emergency motor for when it inevitably breaks down again.
Hi Rob, Love these vids, just the best ! Can this idea be implementated into the base of your wind generator, lowering the torque needed on the turbine to turn it ? This, combined with magnetic bearings would make the turbine shaft much easier to turn, especially at very low wind speeds. I'm thinking of all sorts of experiments with this design. On with the building ! Cheers from Australia !
If you could divide the coil's AC you could use the two transistors one as a motor and the other reverse coil voltage as a generator.. Kind of like a bridge rectifier circuit for a joule thief motor? Though it would have to compensate for back emf so it would not be unity.
I find myself in a situation where I can't get hold of high quality magnets and that has made me wonder about a way to make a generator that doesn't use permanent magnets. We can use electromagnets to make universal motors but what about using electromagnets with a small initial charge like a battery to make a "universal generator" or something like that? I wonder how the efficiency of a setup like that would compare to a permanent magnet generator and I figure that you would probably be just the person to investigate that.
why using another coil?? get output from collector of the transistor, there will be Back Emf when transistor switches off. utilize the drive coil as a generator as well 👍
Yeah that's exactly right. That's a blocking oscillator at its essence. With an air core coil on a cardboard tube we call it a slayer exciter or wound on a ferrite toroid we call it a joule thief.
I’m not an electrician but I think I might have understood the diagram you showed. I think I would have understood it better if you animated the graphic to point at which coil you were talking about, etc. I love your videos even they are sometimes a little over my head.
Okay, Another awesome video. But, I have a simple question. What if you took the output of the coil you were holding and fed that into the "motor"? Would that make the motor run off the output of that coil? That would be very cool. Maybe with the maglev bearing to reduce the friction.
Mmm, I'd guess the wire and coil losses plus magnetic feedback would kill it. It's one thing to drive LEDs and something completely different driving a generator, which requires torque and a stable RPM while maintaining a load.
Schematic seems wrong to me. The transistor is initially Off, so there is an open circuit between the vcc coil and ground. The other coil isnt connected to vcc in anyway so no current flow there either. The base coil has to go from vcc to the base, not how you have it. It wont oscillate.
The spin he gives it excites the base through the coil connected to it and the ground. It doesn't need to be connected to the vcc. The only one that needs to be connected to the vcc is the drive coil, which it is.
@@justtinkering6713 no worries mate - it's a good point - without spinning you are dead right - you tie it into the spinning so it becomes self timing - so to speak
So what is the idea behind using the joule thief motor as a generator as in this example you're using the rotation of magnets to get energy out of the spinning motor. But that seems like a rather inefficient way to transmit power? The joule thief motor is also not very power dense in its design it seems
Hi, how can I email you? I have a computerized sewing machine that I bought by mistake from Amazon US on 2019 (it can't be refunded, I tried) and I wonder if it can be made to work for the UK. I understand the issue with the voltage.
I must be being really thick, you put mechanical energy in to start, then input 1W of electrical in to get less out but at a much higher voltage, what is the use of it as a generator? 🤔
@@FractalMachine Haha, yeah that's basic number theory and you're quite right. If there's an odd number of magnets (and you're right, there is), the net effect is the same as having 5 magnets that are all the same and a 6th magnet that's irregularly shaped and twice as wide lol. I can't imagine why he did that.. probably just ran out of magnets. If you want a uniform field pattern though you need an even number of magnets.
Worth pointing out that you won't get more energy out than you put in. Shouldn't need pointing out, but some might see the higher voltage as a rabbit hole entrance as it is more than 5V, but you have to think in terms of power, V * I in will be less than V * I out, guaranteed :)
I saw quite a few flashing lights in your latest videos. May be a warning at the beginning for such event might be useful for people with epilepsy issue - just a thought :)
I really enjoy your videos and watch every one of them. But I don't get the point of this particular one. What's so special about attaching some magnets to a motor and show that it generates something ?! You've done this dozens of times before but with wind. I don't get your point, sorry. Despite that - keep up your great work!
The intent is to capture the benefits resulting from the phenomenon of electricity spiking when the magnetic field collapses. It took me a few months to wrap my head around too. Not alone =)
Wait. What... I thought Luke was your Son. I'm pretty sure others think the same. I can't say what Video, but I recall the conversations about it. Hmm now I feel like a dummy.
Oh boy Rob, you gotta be more careful naming these videos. Is it a motor or a generator? About 80% of the commenters seem to think it's a closed loop or that that loop _can be_ closed.
Is this a con "Liberty Engine 2"! No if you got right electric motor with a phase on a Supercaps.! Get a better Supercapacitor and 3,5 kWh! it work and it give enough for hours! But is it a con? If you know this, it is okay! Otherwise ohh Yeeahh! It is a good con!!!🥸/Mikael
