One of the better videos. 99% of them have no idea how a charging system works. The cutout relay stays connected until the generator output drops too low. Then it disconnects till you have enough rpm to charge again. Keeps the battery from draining down.
The purpose of R2 and R1 in series, is to shunt some armature current to ground. (R1 also enables minor field current to start flowing). This current energizes the cutout relay coil so that the armature can connect to the battery and charge it. Without R2, the cutout relay would never close because the coil has no path to ground. So, R1 and R2 are there to start the charging process. After the cutout relay closes (connects armature to battery) the resistors are not needed because the cutout relay remains closed until the generator stops rotating.
Greatest explanation ever! Thank you! My RCCR coil is keeping closed even when not energized and I was trying to do some research. In the mean time, I ordered an electronic regulator so I am not at the peril of mechanical defects.
To Airplaneinstructor: First, thanks for the video. Took several times watching it before it all finally sunk in. Question: Could you use a Type A (24 volt) voltage regulator with 2, 120 volt AC to 12 volt DC regulated battery chargers in series. 40 amps DC max current.
Only thing that is maybe wrong is with regards to the RCCR. The upper coil is to repel the spring and force the contact open the bottom coil is to close the contact and allow generator voltage to go to the load. When you mentioned the bottom coil repealing the contact you lost me because the ground for the bottom coil at the RCCR only goes to ground at the generator other than that very good video.
My battery drained I replaced voltage regulator 3 times. And repaired generator 2 times and still have problems not charging battery and when I turn lights I loose power
You need to point out the diagram you're using is for a externally grounded generator. There two types internally grounded (general motors / Chrysler) most Fords etc used a externally grounded. They have to be polarized different. And some Bosch generators used a isolated field which is basically a internally grounded unit. The cutout relay is needed because generators don't have diodes ! There pretty much EMP proof but the regulator isn't as foolproof. And at about 1300 rpm the contact points are vibrating about 1000 times a second. Not a bad video. Take care.
I’m working on a 1946 Funk it has a Delco Remy generator and voltage regulator the wiring diagram I have is unreadable. Could you add the master switch to the diagram. The generator itself Test good grounding the field. Hard to see behind this panel but I currently have no charge due to wiring or bad master switch and that system.
Im interested to know can alternator magnet type use such voltage regulator? how much I did understand it wuld send continues curent and high voltage to the regulator. I dont have availabel solar regulators in my land and actualy I wanted to see if tractor delco regulator wuld help my alternator charge baterrys at low'r speed ranges or use avr or other closed loop system that has nothing to do with positive or negative on the alternators side. So Im woried to fry my baterrys so wuld it by posibel to use those old dc systems like current cutt out selenoid and similar? Honestly I love engine conversions and to use hv capacitors for plasma and amplifier ignition systems so I come across unusual problems my delci 12si cutts in at higher rpm rangers or starting charge get activated at 2500-3000 rpm and Im cinde if anoyed at that thing. So me other question wuld by how to calculate voltage and amps going to the rotor and specific alternator speed ranges wuld it by possibel to manuali set fixed alternator out put via resistor/capacitor box? Peopel are not specific about those things . And last but not least what wuld happen if you reverse direction on the alternator ? Expecialy on tractor alternators I found out some of them wont charge baterry if you buy wrong alternator turning direction and if that external capacitor is dead the alternator wont charge so is there by any chance logical explanation why this happes?
If the current limiter contacts or voltage regulator contacts open, doesn't the field current still have a flow path to ground through R1? If that is the case, the field current can still be maintained, thus never decreasing generator voltage. Help me understand if that statement is wrong.
nevermind. I got the answer. I believe the author might be a little mistaken in how current through the field is reduced, though. At the 6:24 mark, she indicates that current flow through the field will STOP due to the current limiter contacts opening. However, current will still flow through R1, but R1 greatly reduces that current so the field flux dies down, reducing generator output voltage. Also, her arrows through the generator are slightly confusing. I think the arrows should be going from the field windings through the generator, demonstrating that the magnetic field is being generated by the field. Those lines of magnetic flux cut through the conductors as the generator turns, thus inducing a voltage. Because this is a self-exciting generator, the field is going to take a portion of the current now flowing out of the generator and use it to maintain the magnetic field. This keeps generator voltage where it needs to be.
Statements are contradiction 1st polarised and not. When relay is open writing electro magnetic field when relay is open very confusing I need skiped to other video thank you 1st 4minits but statement & writing are contradicting I love driwing exponation thank yohbut whem cirkit are open please do not drow current still flowing on open cirkit
Yes Gwen, Magneto's do too. But generators have a wound field to make the generator more powerful and to be able to control its output, whereas an ignition magneto uses permanent magnets.
@@1shARyn3 Hello Gwen, Some magneto's have permanent magnets and produce A.C. but are called alternators, their output is then turned into d.c. by rectifiers to charge batteries. these so-called alternators are found in motorcycles, larger 1 and 2 cyl. gas engines outboard engines for boats, but in reality they are magneto's. Even Henry Ford's famous model T ford had a magneto that worked the headlites horn and four ignition coils. You are right about alternators, they have a rotor which is a rotating field externally excited by a battery, like the typical auto alternator, much larger alternators have their field's excited by a smaller generator known as an exciter. car generators that produce d.c. have an armature whose windings end at brass segments known as a commutator and field poles wound with many turns of lite gauge wire making them very sensitive to voltage. Edison's generators used for lighting were also direct current machines quite large and had a wound field as well. Some generators are shunt wound, wired across the armature with a rheo- stat in between to vary the field strength. also series coils could be used, wound with the same gauge wire the armature, called a series or commutating field. There is a slight magnetic field on a d.c. generators pole shoes, so that the generator can use it to start building up the voltage at the armature and a small portion from the armature goes back to the field coils, thru a voltage regulator to keep the gen's voltage within operating parameters.

Thank you very much. I was been wondering about the purpose of R2 the whole time.
Thanks for this very lucid explanation. I learnt a lot from this.

Did you find an electronic regulator? If so, where please?
Nicely described , thanks 👍

Won't it also prevent your car from starting if it's bad?

Whooo A&P training
RCCR reverse current relay Current flows from GEN to Bat ONLY.
I Still don't understand what R2 does, please help.

I remember years ago many years ago and there was two types of generator systems I think one was an A and the other one was d circuit
Madam please make a video on BROWN BOVERI REGULATOR?? PLEASE
important point that is always ignored in these explanations - Hysterisis - wont work without it
