@@thebirchwoodtree I saw this the first time when I was a kid and visited the "Abrafaxe Extavium" in germany. They had a bike with a generator and besides different light bulbs (incandescent, "Neon" (energy saving), LED etc.) they also had a toaster... After pushing the lever down the bike felt like it instantly slammed the brakes as it is actually quite a lot of energy to only keep the magnet engaged, nevermind feeding the heating coils with "only" ~600w xD. They had a lot of devices plugged into that bike for kids and parents to try out. I only remember these and a fan though

@Kycilak
@Kycilak 2 ай бұрын
@@megaman1997ful Because you cannot create energy out of nothing. The speed of turning the generator gives the voltage, but you may draw different current at the same voltage, meaning it has to be possible to generate different amounts of power using the same crank speed. The only things, that affect the power generated, is the speed and the force (alternatively the torque and angular velocity), and with constant speed, the only thing that may change is the force. Hence higher power draw causes the need for more force. As per the mechanics this is caused because the current flowing through the generator coils produces magnetic fields that oppose the change caused by the rotation of the magnets in rotor. When no power is drawn, no current flows, and there is no resistance (ideally). When the power draw increases, the current rises and the magnetic fields opposing rotation are stronger, hence one has to crank against more resistance.

I have a bank of 6x 3000f supercapacitors in place of my car battery in my TDI. Starts very well if fully charged. I have a 5w solar panel on the roof and charge controller to keep it topped off if I'm not driving it. 6x in series is 500f. I don't recommend anything less after using it for about 10 years now. They will only give you one or two tries before the voltage is too low to start the engine. Another benefit is they charge up in seconds. So 10 seconds or so it's charged enough to reset the engine. Would be excellent for delivery vehicle, postal service, etc that have a lot of stops and starts. The few times I've had to jump it or put a charger on it to charge it back up took only q few minutes to be fully charged. A jump is only 10 seconds like when the engine is running. The cheaper jumper cables get hot with the amount of current running through them. I've also been able to jump start other larger vehicles and pickups with my car and a good set of cables. People are always scratching their head confused when they see it

You should move to active rectifier instead of passive diode one. At these low voltages, you lose most of your power in the diodes at the moment. For ultra low drop diodes you will lose 0.2V per Diode which is around 10% for your voltages, for classic diodes (which you seem to be using) its 0.7V per diode resulting in quite a bit of wasted energy.

Another idea for improvement is to put 2 thick steel discs on the outside of your magnetic rotors. I believe this would increase the magnetic field by containing it within the steel discs. Also this could somewhat increase the fly-wheel effect. Maybe the coils also could be wound around (or in-between) the steel cores to even better direct and improve the magnetic field.

High performance axial flux motors generally use either 2 sets of coils, one on each side of the magnet rotor, or 2 sets of magnets, either side of the coil stator, to maximise flux through the coils per unit weight. Obviously this doesn't need to be as optimised weight wise but I suspect a twin magnet setup would be better for increased flux density over trying to direct the field with steel

Hey Tim, been watching you for over half a decade. Your generator came out beautifully. It looks amazing, seems to operate smoothly and work eficiently enough for it to have some practical use. It's great to see you do more electronics as well! Something I struggled with in electronics was understanding voltage and current and it's relation to watts and using the "correct" terms that other electrically experienced people will understand. I'd like to share a concept that works for me. Power = RPM x Torque Power = Voltage x Current I see RPM as Voltage, current as torque. When I look at the charged storage in your generator I imagine a metal flywheel spinning relatively slowly (low voltage) but with a lot of mass (available current). When that flywheel is charged, your brain may not think "what do I do with all this speed" (or volts), you may think of it in terms of power instead.

Tom, the only real way to know how much your generator produces is to get a maximum power point tracker and a suitable load for it. The load impedance must match perfectly the impedance of your generator, at which point you measure the power dissipated on the load, and that's your generator rating, for a certain RPM of the generator. Would be cool if in the next video you would do that, because I'm quite curious how much a hand cranked generator will make.

You have the problem of transferring power when you do that. Tend to ark and cause corrosion having you wires stationary makes it much easier. Unless you are just talking about making a stacking generator. He hints at that in the video when he talks about the series parallel configuration. You'd get more amp/volts depending on the configuration. The ends though waste magnetic field if it's not directed back in with some ferromagnetic material, or a Halbach array Generally want your ends to redirect the field back in where you are capturing the work. That said it's harder to deign and heavier so where weight is an issue you don't always or to the same degree. Worth noting that the coils when this happens generate heat, copper / aluminum are diamagnetic and appose the field around generating the power. More work More heat more coils even more heat. You'd run a good risk of a PLA generator melting without regulating that extra current or adding in thermal correction with airflow or convection. Not so bad with a hand crank but a wind or motor driven one would Definity suffer a meltdown. Much like an induction heater.

The low reluctance path needs to be laminated otherwise he will get huge eddy currents. Perpendicular to the direction of magnetic flux, a bit like arches. Maybe he will get away on bother outer sides with only a flat plate, since the field of the magnets is much more dominant compared to the induced field of the stator. Main benefit will be if he can provide a low reluctance path for the stator coils (filling coil with lamination). Big benefit with the axial machine is, theses paths are already short by design (different as in radial flux machines)

This type of motor works well, it is called an axial motor. Backplate would be nice, but only if laminated perpendicular to flux direction. This would mean like an arch of bricks between each coil. Winding layout should be 3 coils for each pair of magnet (easiest, classical synchronous machine). And the interconnection should be diffenent. It sure works with all coils in line. But he gets big circular currents driven by voltage differences due to the coils seeing different fields - also depending on winding direction of the coils (clockwise, ccw).

Would be interesting to see if you can engineer it for using leg muscles instead of hand. Hooking it to your shoe and hanging it from your belt would allow you to use the far larger muscles in your leg. Charging at battery bank at 12V and 5A could be done in a few minutes but would give a whole days mobile phone charge.

I like this build. As for not wanting to crank the generator for more than a few minutes at a time, you could solve that by converting it into a pedal crank and use your legs/feet instead.

Very cool. I do wonder if it would be more effective to make the crank a bit shorter to raise the overall rpm of the large gear, though, I don't have this thing in hand, so maybe I am imagining it in a very different way and it would just be less practical as you would technically be exerting more energy to rotate the crank.

I just want to see two more stators for the outside. Also a clamp built into the base to grab the edge of the table. Also a stacked gear to get more rpm. It would suck to crank for 1 hour to charge your phone but a battery or capacitor in line would work a treat.

In my high school electronics class we had a really nice crank dynamo. We used to compete to hold it by the outputs and see how fast we could turn the crank before we dropped it. The gearing was strong, so I don't think anyone even got past about 50 rpm.

Great video, just use a Delon bridge circuit at the output. That circuit doubles the alternating voltage and rectifies it to DC in one turn for your purpose with only 2 diodes and 2 capacitors. Giving you a higher output range and also enough voltage when cranking with slow speed, afterwards stepping down to 5V USB e.g. as you show.

Cool project! How about improving the design with a planar gear in line with the axel. Device would be more compact, more stable, more solid and you could make the non-crank side grippable by the other hand. And as other mentioned pop some super capacitors or lipo in the unit with a charging regulator and a usb plug (even better a multi-voltage USB-C plug) in addition to “raw” output. Next step would be to make the hand crank interchangeable with a pulley. Combined with a make shift water wheel and semi elastic cord you have a small ad-hoc hydro-power generator. Next step would then be an interchangeable and foldable wind propeller…😊

Use the capacitor bank to a step down converter to charge a phone etc then once you charge the bank you won't need to keep cranking the handle. Mine powers LEDs for upto 45 minutes after 10 minutes of cranking. Thanks for sharing. Yours gives more power output than mine. 👍🇬🇧

It should be possible to get a glow out of a household AC filament bulb using this setup. We had something very similar in GCSE science about 35 years ago. It really drove home the equivalence of difference energy types to actually feel with your own hands how much harder the crank was to turn when the light was switched on. Not sure PLA would take the forces needed though.

10 years back, I was very passionate about this when I was in my 4th or 5th grade so then at that time, I made one handheld model using 2 CDs, a cricket bat handle, a long rubber band, an LED, a few wires, and a DC motor. It was one of the first few things I made as a child (who wanted to be an inventor 😅😅😅).
