Youre video is actually legit. i like it. you're not just hiding a battery somewhere tricking people

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

You seem like a very Honest and honorable human being giving the people truthful insights on technology

Im so impressed about the way that u teach on how to use alternator as an alternatives free energy. I love the way u talk fluently in english, some indian guy who make some tutorials on youtube is using the local dialects which in turn viewers may find difficult to understand...

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.

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.

ALTERNATOR: "So, guys I'm so exited... I'm about to lose control and I think I like it!" XP

Gained a Canadian Subscriber from this video! Very amazing, you are a genius and your English is very easy to understand! Thanks for your time!

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.

Ein selbsterregten Generator wie eine Lichtmaschine in einen selbsterregten Generator umwandeln, Respekt...😄😄😄😄😄😄😄😄😄😄😄😄😄😄😄😄😄😄😄😄

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.

The most abused RU-vid practice is not bogus videos purporting to show the viewer something never before seen while actually doing something quite ordinary just outside of camera view. The Most abused RU-vid practice is the video "Titling". The practice is pervasive because everyone is vying for viewers and subscribers. So this method is used to suck viewers in to this highly competitive forum. Mr.Electron, You have enough grasp of electronics to make it your career so please don't fall into that "MISNOMER" trap. Please think honestly about your video title. I don't make hit and run statements. So I'm willing to debate this. Besides my objection to your title I found your video entertaining with no obvious errors or claims. I did, in fact click "Liked" and will probably follow your work! Wakodahatchee Chris

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.

"Self excited"? Proceeds to hook up battery.

You are doing nice work.👌👌

Very Good Explanation......it is nt fake....absolutely Congrats the valuable informations....

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.

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.

It did work because when there is no electrons in other end; it is not magnet to suck electrons from atmosphere, so it is just metal.

No idea why all the dislikes. Excellent info. Thanks.

You should never connect an ammeter directly across the output terminals of the generator as this is not a good test for the amperage of the generator. The ammeter on its own provides a short circuit and so very little voltage is required to get a high current. The self-excitation could be improved through magnetizing the rotor or adding a permanent magnet into the rotor. In a self-excited generator, the value of the resistance of the field has to be related to the voltage characteristic of the generator. There is more than simply connecting the output to the field!

Congratulations! You discovered how alternators work. Where is the "self excitation" part?

Very good video, I like it. What if we connect a fly wheel on alternator so that output can last longer. This experiment is worth giving a try and make a good descriptive video on it. Thank you 🤗

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

I had the idea of hooking an alternator up to an exercycle, but it appears you've beaten me to it. :-)

Very nice video

Very interesting. Plus, it's a holiday here in the US so I can watch videos and learn some stuff about electricity - which I HATE - all day long. I'm working on a little solar setup with my clumsy, mechanically-minded brain and watched some videos last night so am beginning to understand some things and electricity is getting less and less scary. Thanks!!

This man gets excited a hell of a lot

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

Got an easier way to excite your alternator, you don't need the battery. Disassemble the alternator. Stick one of the magnets to the inside of your rotor. On the rotor, you have the triangle teeth like shapes that surround the coil. Drill a hole just large enough to put the magnet in one of the triangles. You have to work out which way the magnet goes in - North facing up/out or South facing up/out. Reassemble the alternator. Reconnect your wire and resistor and try again from 4:00 in your video. Their you have it, a self exciting alternator with no 3.7v battery.

I like your educational videos

The brushes are independent and insulated from the body so you have to connect both sides of brush

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!👍🤜🏼🤛🏽👌🏼🙌🏾✌️

@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.

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

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 good, you are the best man now and forever

I have searched for a clear explanation of all this. This is the most clear concise video ever Thank you. two questions, why thw filliment. why not a jumper. why not just connect a little motor to spin it? thanks again.

Excellent I learnt from you how to check the Altertor.

Self exited means a small voltage turns it on.Its a electromagnet and is turned on when ignition is on.Exicted means it turns on only.This small voltage has nothing to do with output.Tinker toys or building blocks might suit him better.

Very good project 👍

Nice Video bhai 👍

I suggest you would use a portable hand-drill to achieve the alternator's rpm . You will be surprised.

Well I am really impressed with your teaching but one thing I get I don't get through my head how is your multimeter running even before you even pull on the string

But this is a well known thing by engineers and auto repairmen, the exciting voltage for the rotor comes from the ignition switch, but goes through the regulator built right into the alternator.

Dude ....that was phenomenal

might be if you trigger it with a short connect to the battery? that means for somehow a voltage is applied alternator is self agitated! cool

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

Well explained and a great alternator...thanks for that

Did I miss something? How can a high speed none modified alternator make 12v at low speeds? Exciting it early does it?

You must remember to yourself, because only by remembering oneself, your change is possible.

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.

Äääähmn... why all this tinkering? The Electronics inside tha Alternator is doing all of this for you and it regulates the exitement current to the point, whre it puts out 13, 4 Volt (usually 14, 4 Volt) regulated. Unse the control connectors on the alternator for this purpose. In "normal" operation, the Thing gets 12 Volt when you turn the Key to position 2 in the cockpit. ;) I have built a wind turbine, several years ago. To exite the alternater only when the wind is blowing, i mounted a piece of sheet metal to an micro switch. (wind == switch on) (no wind == switch off) That way, the battery bank would not get drained during calm weather. Anyway... i diggress... keep on doing your great work. well done. Greets from Germany.

Now I know what leaves are for.

Świetna robota ! Pozdrawiam

A simple blade connection or original Exciter connection with lead tails is best to excite with

always wondered why they couldn't have something like an alternator built-in kind of like a traction motor in the wheel that way when the car rolls it spins and creates juice to charge the batteries as you're going

Awesome ideas!!

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 🤔

आनेवाला व्हिडिओ देखने के लिये मै वेट करुंगा 👍👍👍👍👍

We can run a DC dynamo by using 12 v adpter

Howdy. Technically that is not self exciting. It uses a battery to magnetize the rotor. Old car DC dynamos were self exciting. The trouble is to generate enough voltage to overcome the 6 pulse bridge rectifier forward voltage of 2x0,7V = 1,4 V. If the bridge is 3 pulse the forward voltage to overcome is 0,7 V. The residual magnetism in the rotor seldom induces enough voltage to overcome. 3 phase induction motors are sometimes used in petrol generators to produce 115 V or 230 V 3 phase AC. The trick is to use capacitors across the poles to generate exactly the same amount of capacitive reactive current as the stator produces inductive reactive current. Usually this setup is self exciting. If not a 1,5V dry cell may be momentarily connected over any poles to start the self exciting. Alternatively a magnet may be placed on the stator for a moment. I wonder if a magnet on the pulley would be enough for the induction to overcome the rectifier forward voltage ? I might try that. One problem could be over excitation at high revolutions althoug the regulator has cut off the rotor current. Regards.

Well explained bro...thanks for the video

I need a trick similar like this to test some old alternators I bought on used parts.

Dear friend, I am one of your followers, I want to suggest to draw an electric plan for your circuits. I think it’s very helpful. Thanks.

I think this method using electric bike alternator output dc to dc 12v convert to 72v bro work or not

thanks for elegance videos can I have your idea that what is the best solution to use all petrol engine HP for an electrical generator? attaches multi alternator through belt would work? or should design dedication gear reduction and generator like a commercial portable generator?

Did you tear down the regulator? If there isn't the regulator how can it keep the output at 12 volts?

Hi, what is the resistance wire thickness, does it matter which gauge is used. Enjoyed watching the video it was very well done thankyou

I feel an idea of connecting the alternator to an 240 volts 1000 watts ie 1kv AC inverter which works on 12volts along with an12volts 100 amps battery. when the inverter starts working producing 240 volts 4 to 5 amps current is given to a. AC motor which is capable to rotate the alternator which the motor has high speed rpm so that alternator produce full 12volts which is fed to the 12volts 100 amps battery. When the alternator rotates producing electricity will charge the battery at the same time it makes the inverter works on alternator power too. This method automatic charge system of the battery without line voltage. By implementing this method you can produce electricity without even solar power. ACBS ie automatic charging battery system

I love that insulator it’s eco friendly lol

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 😁)

what the (felement wire) you are talking about? is it a high resistance wire? and why you have use please?

You're the best! Thanks for the amazing videos!

Try using a shorter pull cord to get the alternator up to speed.

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

A negative times a negative equals a positive 2 wrongs don't make a right and 3 rights make a left

No this is not actually factual, the alternator is designed to charge the battery at 600 RPM

Electronics is Fun!

Looking at the comments, am i the only one who thinks what you're describing is weird. With the field coil joined to the rotor coil you essentially have a shunt wound motor (assuming you've removed the regulator and bridge?), the small battery cross the rotor, may as well get a permanent magnet and be done with it, that diode will half wave rectify the energy changes in the rotor which will be seen as back emf and will charge or over charge that lithium cell. Apart from that connecting a load to the field coil and seeing magnetic flux converted into electricity, isn't that pretty normal when the rotor is energised? What r u trying to achieve?

Well I've never had a problem achieving self excitement with human hand - anyone else? 😳

Very good sir, thankyou for showing this video

Calculus 90 Watt. Alternator can. we self run and give a bit extra for the house.

What is purpose of cut out attached between alternator n battery in the car?

Ninety amps. I never would have imagined it puts out anywhere near that. Did you add a zero by mistake?

So the maximum voltage it can produce is around 13.5 volts ? That means only the regular 12-14 volt battery can be used for charging.

Good job BROO CAN I USE, USED ALTONATOR TO CONNECT LIKE THIS AND TO WORK????????

My alternator come self-excited do I still have to put the battery to it to make it work

There is a screw terminal on the regulation disk unused that will make a negative screw terminal with regulation diodes I'm use already

Can alternators be combined to produce power to do some work. OR to do MORE work?

BRAVO!! EXCELLENT!! Teaching!!

Thanks you for sharing my friend...

why only 3. something volts only is the voltage supply of the artificial magnet should i use 12volts for better performance? if no why ... this part only im confusing

It is a nice job bet please I want to ask a question what do we do to DC motor to stop it from drilling battery

Superb. I learned such a lot. Thanks.

Hi great video and explanation but will the output be uncontrolled in this mode

A 3.7v lithium battery is "really good charged", aka full, at 4.2v. It is empty at 3.2v. The nominal 3.7v is just the middle value.

If use a bigger magnet 🧲 the motor can be faster 😮
