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.

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

[@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.

[@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.

[@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.

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.

[@PF-gi9vv]

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.

[@mytechtrials]

[@MaqboolAhmed-o9f]

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

[@carmelpule6954]

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!

[@donnypeterkin3336]

Or even better, connect a battery to it, then the regulator will take over after it reaches 13.5V

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.

[@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.

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.

Not advisable! That arrangement is known as "full fielding" the alternator, which will burn out the field winding as well as remove the voltage regulator from the circuit.

[@user-wangyu]

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

[@eugenepohjola258]

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.

[@eugenepohjola258]

Howdy again. Experimentation showed that outer excitation needs be about 2 V to the rotor. The current needs be about 200 - 300 mA. After that the alternator will self excite up. Magnets had no effect whatsoever. A small solar panel may be used to deliver constant pre-excitation. Only works in daylight, of course. Another solution may be to let some kind of wind hinge operate a micro switch to excite a relay that connects 12 V to the rotor. Regards.
