BRUSHLESS ALTERNATOR

[@fredwupkensoppel8949]

Engineering (machinery, code, networks and so on) would not be the same without India. It's always a channel with hundreds of thousands of views and few subs that explain the important bits to give students all over the world the "aha!"-moment they need. Shoutout to "manchester encoding in two minutes".

[@mikebrady9625]

What a great explanation of this technology. I'm rebuilding a genset at the moment, and while I have a good knowledge of the diesel component, the generation side was puzzling. It now makes a lot more sense. Thanks for taking the time to put this tutorial together.

[@bjusticeforever]

Thanks a million! I recently bought a brush-less generator and really needed some background on it's operation. Very informative!

[@jasonswindall7261]

Best alternator video on KZbin. Thank you so much! There are no other videos which explain the excitor system and AVR.

[@missing1person]

hands down this the most valuable video you find on gensets

[@yousefshello582]

Thank you very much, this is the first video on youtube that really demonstrate how a brushless alternator operates, Thank you again

[@ritwik516]

Glad to know that you like it !!! Thank You...

[@brentmartinez7663]

A very informative video. Thank you so much Rit Wik! You even provided how to troubleshoot the generator. Really helpful. Please keep it up!

[@arrchee88]

Very good video or multi-media presentation, this will help other people on their search on how alternator-motor works. Thanks a lot for the upload.

Excellent video and very simple explanation.Great work Rit Wik....The doubts about alternator was cleared very easily. Certainly I will suggest your videos to all my technical friends.Thanks .....

[@ritwik516]

Thanks Santhosh.

[@Htube78]

Rit thx for the video , but how does the regulator supply power to the exciter stator, where does this power come from? I know the regulator senses the output voltage , but is there any type of other input

[@1210xs]

Htube78 The regulator supply power to the AVR board, and the board adjust the input to the exciter stator

[@pradeeprgatti]

Superb video...very informative

[@kaustavmanna4345]

Good explanation. Very much practical

[@ahmedbadawy3973]

[@sanjoypaul3209]

Hello Sir clearly explained. If two generator are running in parallel , then both alternator KW is same but amps is different then how to make equal the amps

[@amjadhossain5145]

Excellent works bro

[@samiuteulilo9190]

Do you know of manufacture of this type, I’m after a hi performance, small, light weight low rpm alternator.

[@rassanity3292]

So if I can wrap my little head around this, the only reason for not using permanent magnets in the exciter is for output regulation on the main stator? This should be able to be controlled by alternator rpms aswell?

[@ritwik516]

by varying the rpm of engine output from alternator can be changed, but in case of AC output the frequency (hz) will also change, that is why all AC Generators are fixed rpm. DC generators have no such problem, that is why DC generators are variable speed generators.

[@katerinaaspridi8042]

Hi Ric would you then say that the AVR operates as the power source for the exciter? or the exciter is fed by the AC output of the main alternator itself?

[@ritwik516]

there are various designs of BRUSHLESS ALTERNATOR, the example taken here shows that Exciter Stator is having residual magnetism. The AVR gets input from Main Alternator (Main Stator) output (AC) and provides excitation current (DC) to the Exciter Stator.

[@katerinaaspridi8042]

Hi Rit, thank you! So the AVR is also able to convert AC into DC? many thanks

[@AsifAhmed-tx3lk]

really amazing explanation thank u.

[@sasaank24]

[@gokulrajraj1039]

Sir, if AVR is not working, can we manually control the exciter current through rectifier and potentiometer arrangements?? Please reply sir

[@josephrodriguezrodriguez26]

great video! thanks from chile!

[@user-ji3xv6lw1b]

is there any transformer between stator phases and AVR inputs needed?

[@ritwik516]

No, transformers are not used in AVR. The AVR houses an electronic circuit board, consists of Diodes, Transistors etc.

[@aamirawan2720]

good explain sir thanks

[@shridharacharya134]

[@AzharShaikh-su8bl]

Sar ac to dc alternator hy problem ye hy ke kam jyada voltage Bahar aa raha aur avr ka fuse ud jara to kya kare coil sab sahi hy

[@katerinaaspridi8042]

Hi Rit, excellent video! I have one query, for the alternator to be self-excited I thought that the process relies on the residual magnetism of the main generator rotor however you mention the residual magnetism of the exciter stator? a clarification would be greatly appreciated! thanks!

[@ritwik516]

Exciter Stator has residual magnetism. When Rotor moves AC is generated in Exciter Rotor, gets converted to DC by Rectifier Assembly and goes to Main Rotor. Moving Main Rotors induced AC current in Main Stator. I hope now you are clear ? Feel free to ask again if in doubt. Thanks Katerina...

[@katerinaaspridi8042]

Hi Rit, thank you for your reply! my question is: when an alternator is started again, why is the exciter stator residual magnetism used and not the residual magnetism of the main rotor? and where does this induced voltage (from the residual magnetism) go? does it go to the amplifier in the AVR? cheers

[@ritwik516]

Hi Katerina, it is a very good question !!! Theoretically Main Rotor residual magnetism will generate output in Main Stator terminals. In practical application, the load connected to alternator fluctuates. Examples of load are AC, TV, Bulb, Washing Machine etc which are using the electricity generated by the alternator. If load reduces, alternator output will increase and vise versa. This is not desirable for practical applications. We need a STEADY OUTPUT. The AVR helps to maintain steady output by little manipulation in the excitation current of Exciter Stator. Main Stator's output acts as input to AVR, and AVR output is input to Exciter Stator. Working of AVR involves complex electronics. It will be a separate topic. I hope your doubts are cleared !!! If not, ask again !!!!!!!!!!!!!!!!!!!!!

[@eliazarperez7367]

+Rit Wik Amazing explanation, thanks for it. I have two questions. If I dont have a diode, may I disconect F1 and F2 from the AVR in order to not damage it when conect the 12 volts battery to the stator exciting coil for restore the residual magnetism? what do you mean when you say "Check that the speed is 4% of the nominal? Thanks a lot. I hope you make a video about AVRs.

[@ritwik516]

Answer 1: Yes, you can disconnect the AVR and connect battery +ve to F1 and -ve to F2. Hold the connection briefly, 1 sec should be sufficient. Answer 2: If rated rpm is 1500 then a speed range of 1440 - 1560 is fine.

[@golgothapro]

The recorded audio amplitude of this video is so high that the signal is "clipping". Please reduce the gain for future productions if you don't mind. Thank you.

Extremely helpful, thanks

[@vijaykumarhudge2216]

Very useful for troubleshuting Thx pl tell in hindi ya marathi

[@scamper_van8470]

bookmarked that video coz i'm in the process of buying a self exciting alternator.. and that will be helpful in case my alternator get in troubles.one question tho... i haven't understood yet does self exciting alternators need external motors to generate electricity or not?? on that video i understand that the internal motor will move the rotor on the alternator side.. have i got it right or wrong?

[@ritwik516]

You got it right, we need prime mover (engine) to rotate the shaft of the Alternator.

[@hc.lalrinliana1703]

Very helpful

[@readyTOexplore208]

After rectifier their converts ac to dc, to the main rotor, then how to generate ac for main stator

[@readyTOexplore208]

And why not give directly ac why changing the currents ac to dc

[@kikecroatia1777]

a saw this alternator produced by Slovenian car electric factory Iskra,he is so complicated!

[@ELECTROMARINEMANIA]

simple super bro

[@hichamhayyat3242]

Thank you very much brother

[@sunshine7453]

Excellent! Thank you a million!

[@brawlbaby4911]

so exciter is basically a small generator inside of a bigger generator whose output is rectified.. am i right?

[@ritwik516]

Exactly...

[@alvarobejarjimenez3850]

Hi, I'm looking for a supplier of brushless generators for a small wind turbine, however, it turns out that I am only finding brushless motor suppliers. Could you or anyone else recommend me any brushless generator supplier? Thanks

this is brilliant

[@marmikdarji3906]

wow nice so amazing

[@291996mohit]

How this increase and decrease of field exciter is happening through AVR?

[@ritwik516]

There are knobs for adjustment in the AVR. There are electronically controlled AVRs also.

[@archnaamol]

Hi can you pls help me to. Understand type. Of windings what does it means by winding 11,winding 14, winding 311

[@TLim-yw6oh]

Thank you so much for the explaination
