Hi enjoyed watching your videos. It gave me the knowledge to build a backup up off grid 12v charging device. Used a second hand 100 amp alternator, cycle turbo trainer, old jump lead switches etc. Basically I can pedal in high gear with little stress on Crank & alternator rotation. Pushing rear wheel by hand has alternator pulley & rear wheel rotating freely. Obviously when exciting you can feel load slightly but you can cycle immediately in high gear. Tyre, inner tube & turbo trainer tiny freewheel resistance roller removed. Belt goes round backwheel & alternator. Turbo trainer folds in half with alternator attached. Bicycle comes off turbo trainer & can be used as normal by just adding tyre & Innertube. Bike kept in campervan with turbo trainer & can be used to jump-start van or charge leisure batteries. Beats charging with a slow battery trickle charger. Basically fully off grid backup.

[@makmak151515]

Guys a bloody genius. I’ve been trying to use an alternator for windmill charging. This is one step closer. Luca

[@bringer-of-change]

It would work for a windmill. This doesnt do anything but slow to a stop as the battery dies, and the more stuff you try to power within this circuit, the faster the fully charged battery will die.

[@damianbutterworth2434]

I cut a 1/2 inch socket extension and machined it down so it fitted into a drill. Then you can put any socket onto the drill to turn the alternator. I also used an old lawnmower engine to test alternators. I`ve made my own pushbike generator too lol. I was lucky enough to work at Valeo repairing alternators and starter motors so I could get all the spares I wanted.

[@montgomeryrichard]

I did this(similar) on a 1000cc BMW motorbike alternator to get max output to charge the battery quickly when used in very cold weather for starting so did not have to use kick starter! about 40 years ago....used the bike battery via a resistor from the ignition circuit so not connected when the Engine off to limit the current through brushes to 4 amps at 12 volts to get the max output without damaging rotor winding (35w headlight bulb dip filament can be used as a resistor (3x12 volt 36 watts, check current through winding when connected to the 12-volt battery to find max current for alternator exciter winding). if the battery was very low still would be enough current to excite the alternator.

[@Donnaya137]

[@jacquespoirier9071]

On the Bosch alternator you don't have to do anything to have it self energizing, just the remanent magnetism is enough to start charging as long it spins at about 3000 RPM. your use of a small battery is a good idea but this can't be left alone because of the decay of the battery, better to use a centrifugial switch and the battery bank to excite the alternator if you intent to use it in a windmill setup. good video.

[@smokyatgroups]

I think the filament is made of Nichrome resistance wire. It acts as a resistor and limits the full output current from passing through the rotors winding (burning it out)

Looks like your method can be use in a rural setting, perhaps put some blades to it and use wind to move it. Connect it to a single car battery for 12 volts or 2 batteries for 24 volts. and use it to power a TV or computer IMHO. Great video.

[@seaperu1]

if you are using led brake lights without some kind of voltage equalizer, it can keep your alternator form charging your battery

[@davidsermon72]

For charging the lithium battery. Simply add in a 5a fuse and a 12v car plug usb charger.

[@lilufabegom4771]

Very interesting

[@sogbryan6633]

@Mr Electron Experiment Suggestion: Try shorting(connecting) all 3 active points (not ground) together on the rectifier. And run the alternator normal like it would be in a car, hooked up to a 12v battery. Everything the same as normal but with 3coils shorted/joined together. Then run the alternator and monitor the battery, I think you'll be pleasantly surprised what happens.

[@jeffokriya3389]

no, it´s not pleasant to generate an unregulated voltage, it´s dumb. Not very useful nor safe because you can burn the Alternator or the load.

[@TreadTalk247]

Wonder if u can do this same process to my 6V classic car which uses a starter generator device? On these old classic (1927) cars the generator output is weak and again the car runs on 6v so having more output would be huge! Let me know your thoughts @Mr. Electron!

[@ggj666]

i'd attach the alternator to a drive belt of a car engine, a lot less work :o)

[@UrbanPovertist]

Awesome ideas!!

[@MrElectron]

Thank you! 😊

[@UrbanPovertist]

@@MrElectron I am currently working on a reverse ran power wheels toy car generator. The axle hole allows you run a shaft thru multiple parts and you can wire for series or parallel for greater amps or voltage. I use hand Crank but I believe if I configure correctly it will run a separate motor and power itself.

[@UrbanPovertist]

Theory. A 10kw generator with a 1kw motor and gearing would power itself and leave you 9kw usable power. Load would surely effect

[@UrbanPovertist]

Diodes and current regulation are key. I run modified led flashlights on solar with car batteries. Voltage doesn't seem to matter except brightness but if you don't drop current they fry fast

We can connect a 12V /rechargeable battery for feeding self excitation . Circuit can be simpler, Only re- chagrining of the battery can be designed.

[@taibnawaz01]

Nice 👍

[@thespiritof76..]

I am very curious if you use higher voltages to excite the roter will the stronger electromagnet field give you a more powerful generator (or motor 😁)

[@denismwangi2666]

thank you teacher can i get a link of the second video pliz

[@Propnut48]

Most new alternators (except an external regulator alt such as a Chrysler Corp alt as almost all of theirs are external reg. ) are self exciting when the rpm reaches around 2000 rpm or so and will continue to work till the rpm drops below 400. Most gm alts have a S/E reg in them now. Wind generators don’t like too much amperage as it take 5 BP to produce 100 amps. It’s better to stay under the 30 amp range. I use a Nippon Denso 12180SE Lester number which is 25 amps with a S/E reg installed. It’s small and can spin up to 10,000 rpm.

very useful, thanks. how do we know what diode do we need in car electronics? since, for example, for a fan we need very much amps. what kind of diode should we use if there's about 500A draw?

High current power diodes. I don't know about the names but you can ask the seller by its Amp rating

Can you show how to make an alternator work like a regenerative brake with a potentiometer or similar being analog that only brakes as much as you press down a brake pedal to make it stop a wheel? Something that I gladly like to see being possible.

[@tmog1000]

The amount of braking effect would be VERY small

[@davemould4638]

The principle is sound. However there will be current drawn from the battery all the time the alternator is not spinning, so that battery will get discharged very quickly if left connected when not in use. You need a method so that the battery is connected only when the alternator is spinning. Also with the charge circuit you intend to provide, you must be careful to follow the recommended charge method for lithium batteries. Incorrect charging will result in the battery being destroyed and possibly even catching fire. The magnets are of course only used as a means to connect wires to the battery. A battery holder would be a far better way to do this. Or hold the 2 wires in place using an elastic band around the + and - terminals instead of magnets.

[@johnd5542]

He should use a mosfit for the battery. The gate would act as a switch when the alt produces power.
