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.

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.

In deed well explained ,i watched many alternator modification videos and this is the first one that i understand everything and can replicate

[@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.

Thank you. Very helpful for my basic understanding. I am not an engineer but now love a lot of things wrt engineering.

[@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.

[@radiochannel64]

[@dennismenace5174]

I like your educational videos

[@precisionguesswork5394]

The problem here is that unlike generators, alternators don't retain residual magnetism. Although small magnets can be incorporated into the rotor to begin the process of producing current, they must be small enough not to allow the unit to run wild. Simple adjustable current limiters can then be used to regulate total output while more advanced regulators can provide rotor current in regard to rotor speed.

[@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)

[@bandido7994]

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.

[@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.

[@mugabeeric5303]

Hullo, I enjoy your videos. Am experimenting on a Toyota land cruiser alternator. I want to make 220V AC with use of AC motor. What is the best way of making the alternator self exciting in this case. Regards. Eric

[@davidrebeiro4887]

Very informative

[@ggj666]

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

[@jeffokriya3389]

Most people here probably don´t understand what you mean by "self excited", erroneously, they think it´s "free Energy". No people, it simply means the rotor´s feed is provided by the Alternator, but this happens in most cars. There is a way to generate free electricity from an Alternator, but this is not it. It consists of defeating the Lenz effect. Which is an obscure secret.

[@akonkoch9971]

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

[@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.

[@orlandojohnson5742]

When he used the toe nail clippers I subscribed.... lol! All this intelligent talking & u don't have a pair of wire snips!? Ikr who cares if u can get some free energy 👍👌🏼🙌🏾✌️ I'd say wire up an inverter & get A.C from D.C. Figure how to power up the alternator without the grid or minimal grid usage!? Kinda like the newer diesel trains!? Diesel fuel/motor Powers up electrical in those trains now!! If we could use minimal electricity to power up inverter power!! We could be on to something!👌🏼🙌🏾 We have step down transformers & step up transformers! There's gotta be away to achieve better results!? We have solar power....wind & water to power generators/alternators!? Jus need enough to power larger AC equipment too! The mini ductless hvacs need to research more! Suspect some have a low locked rotor amperage & full load running capacity! We can "I believe!" do this!👍🤜🏼🤛🏽👌🏼🙌🏾✌️

[@akkaouitv2625]

Bon courrage

[@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.

@@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

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

Yo! I have a 14v 150a alturnator off a mk7 ford fiesta ecoboost. When the 12v battery is wired to the main positive output and to the alturnator body it doesn't need any other wires to self excite. If we want the alturnator to work the same way as it does on a car a 12v battery is needed in the circuit unless you turn the electromagnet rotor into a magnet rotor but I think this will limit the overall output 🤔
