Is this really a dynamo? Why I ask this is because from my understanding a dynamo makes DC power via a commutator to make contact on only half of the sine wave and disconnect on the other half. Without the commutator it would produce AC power. At 5:12 in the video the volt meter is hooked up to the AC scale. But if the little black box on this bike dynamo is a couple of diodes to rectify the power to make this produce DC power then this is working more like a modern day alternator in car. Just a little simpler. I'm not bashing the video. Great to see whats inside one of these things. Just questioning it "for science!". Check out the wikipedia page for dynamo. But if i'm wrong then I got some learning to do.
Most of classic bicycle dynamos are in fact simple AC generators. Why? Because old good incandescent bulbs, can work equally well at AC and DC voltage. So you don't need to rectify it. Moreover, you lose about 2 volts if you rectify it. This dynamo is 12 V, but i think most dynamos in Europe are just 6 V. Today LED lights are common, so there must be a rectifier, or some sort of AC/DC voltage converter, inside the LED assembly.
I saved a cuople of these.I found an old one recently that ddnt turn anymore. I opened it up and it had 2 cool pieces inside. A rotor with a cool looking metallic neo magnet attached to it. And a spool of wire encased in metal casing. I had to destroy the dynamo to get the parts.
Yes, in cycle dynamos that were built approximately before 1960, the magnets were made of metal, for example Alnico. Ferrite ceramics were later used. I have a 60 year old dynamo, with a two-pole metal magnet, that works like new.
In my childhood I was very crazy about such dynamo and light cycle, very few people used such a bicycle in 1980 to 85 .
Wonderful video clear view
Good information 🎉🎉🎉

Boa resposta. Me convenceu! Parabéns.
Nice clear video. It is actually an alternator rather than a dynamo is it not?
Use thicker wire(19,20swg) and give more turns tothe coil to gain better voltage & amperage ???????
Very good Video,importende the Windungen fromm the cool,right and legt die the induktance of the AC...thanks.Matthias
I hve this elephant dynamo from china.am in kenya still using with my byke

Chuck Norris? Only a real idiot would take the name of another idiot. Wow, what an idiot you are!

@@Tag-Traeumer I did nt know that. I think I have only seen that once before in the early 80s.
How can i make the pivot more smooth to accomodate low movements..
at 4.12 u have missed to place a washer before the driving wheel.
Sir, I loved this video and your work but you deserve an awesome logo and channel banner with those amount of subs
Very cool, bro!
very nice information
Eres un gran inventor
Muito bom vídeo meu rei 👋🇧🇷
What’s the details of the winding? How many turns? Make a video of winding too
Very nice👌👌👌
très bien
Arigato . 🙏👍🇧🇷
Muito boa explicação , valeu!
Is this AC or DC ? How much voltage?
muito bom abraços valeu
👌🤗🤗
I like

1 coil turn please
👌👌
ভাই এটার দাম কত আর কোথায় পাওয়া যাবে এই কোয়েল আমার লাগবে
This is a metal body
Nice
wiw amazing
❣️
Awesome
Super
I want to buy this Dynamo plz Inform me
I hve one sir.am in kenya mombasa
...где интересно можно приобрести такой же генератор?
so is this a single phase ac generator?
Yes.
Gostaria de ver a forma de onda senoidal.
Thanxx but this is AC or DC ?
AC and varying frequency.
ডায়নামো তৈরি করে দেখাও
Baaal 😀🔥😎
Stop the disturbing,useless music first????????
It would be better if you named all the parts as you take them off.
80 dynamo 3D kore decor
এটাতো সাইকেলের কয়েল তাই না
Next to the initial schematic diagram (0.05-0.10) it is clearly written: "Actually it is a mini AC generator"
So then why the incorrect title? Would you have seen the clearly written schematic otherwise?
बिजलि युज करके बिजली बना ना ये कौन सा तरिका है
Verbal commentary would improve the video immensely. You provide just insane music and visuals. Dislike.
y do u hate the music?
Cail round ৫০০
Skip the annoying music , for me.
the music is perfect
