Hi, Just spotted a slight mistake that might be relevant in future videos. 26 wires with a diameter of 0.2mm do not equate to a 5.2mm diameter wire. You need to multiply the cross section area, not the diameter. In this case, it would be the equivalent of a 1.02mm diameter wire.

@Robert Slackware Here is an opportunity to triple down on stupid... Go for it... By the way, what your ignorance is talking about is NOT silver, it is in fact, MOSTLY copper, probably coated in silver to get the lower resistance of silver used via skin effects, but the hardness of copper as silver is TOO ductile a material to be used for much of anything.

@Robert Slackware Ah, you did triple down, excellent. That "silver" wire, I guarantee you is less than 50% silver if sold for electrical purposes. Silver is too soft and if used for windings, as you are talking about MUST have an insulating coating on it anyways. Pure silver would not help you any compared to partial. Probably less than 30% silver. And yes, it is Hella expensive.

Apart from the tedium of actually winding them, the different results that were obtained by the number of turns on the windings, diameter of wire etc was quite interesting.

A variable load would take these generator videos to the next level. Its critical that the impedances in these systems are matched so that you transfer the maximum possiple power. You could possibly even try to design or use a MPPT system.

I would surely leave the project while I was doing all the coils. I esteem you

Nice! There's plenty of explanations of Faraday's law and so on for motor and generators on the Internet, but practical number of turns/output voltage for real BLDCs is more sparse. This video has given me much more practical information for my pedal generator for a hybrid bike project. I don't want any gears or chains, the whole point is simpler mechanics. Even after rewinding a BLDC I know I will probably still need some step up gearing though.

Hi friend, a tip from Argentina. Consider use schottky diodes for the rectiffier ;) you win a couple of volts...

Finnaly a video that explains how you can change a bldc's specs :) thanks, maybe I will use it on my electric skateboard to make a direct drive with a low kv

Hopefully a motor rewinding tutorial. I'm thinking of to install a fork-mount motorcycle auxiliary projector headlights set in my bicycle and modify a bldc motor into a generator, and I also think of to make a solar-charging high performance eletric supercar that uses an electroproducing couple designed in a Tesla powertrain configuration for its powertrain. That's why I was waiting for a video like this. Btw, awesome work and tutorial as always Scott

Thanks for the video!!! Love anything related to producing energy! Keep up the great work!!!!!!!!!!!!!!

Hi, as you are always asking for ideas, Igot one that would be awesome. As a hobby I do some FPV Drone flying and for that purpose people are typically using simple sony hs1177 cameras that provide a simple analog PAL (or NTSC) signal. This signal now is transmitted analog on the 5.8GHz band (at 25mW). The downside here is, that with the analog signal a lot of noise is received too. For that purpose a very nice project would be to find a way of converting the analog signal to digital with error-correction and maybe decode it back on the receiver. The main problem here is that the latency has to be as low as possible. For that purpose I'd also suggest to not use of-the-shelf Video ADCs but rather encode the signal line-wise or bundle a few lines at a time. Else collecting a full frame will always introduce quite a bit of latency by itself. And even if you think the above is a little too complicated to accomplish I am sure there would be very nice projects using the cheap fpv-equipment parts available.

I was thinking about this a lot after previous video. So glad you took on the project and made it happen! Really great video! Would love to see if you can reasonably use it in some way to generate power. Like could it be used as a windmill, or something like that?

I love this, thanks Scott

Thank you for answer the questions 🙏

I rewound quite a few motors for my quadcopters. When removing stator you need to heat it, cooling motor base is fine, but sometimes there is adhesive which will give up with higher temperatures. Also threading is common, so you always need to twist it and not just pull. Avoid stator damage by wrapping it in some cloth, leather or just paper. You want to avoid any sharp edges on stator and layer separation. For anyone trying it, consider double lacquered wire, since its more resistant to damage when hand winding. If you need winding scheme for different slots and pole counts calculator on www.bavaria-direct.co.za/scheme/calculator/ can be really helpful. Also use some heat shrink on wires exiting motor. With vibrations motor base can "bite" through enamel and short your phase to metal base. That starts to be problem when you attach your motor to grounded metal frame or something. Simple trick for removing enamel from wire is to use pill of aspirin and melt it with wire. It smells, but its fast and I prefer it over sandpaper.

When I saw this video, I had a question: if I want to make a wind generator, should I connect a modified engine (like the one on the video, but bigger) to the generator shaft? Or should I create a winding around the circumference of the generator and use the motor shaft as the source of rotation for neodymium magnets? I was also thinking about connecting several generators to the circumference of the generator ... it would gain power, but it would be difficult for the wind to move the whole blade system.

Many thanks. Really well explained and reasoned.

good video, I posted a similar method but with a PMDC into a universal motor 2 months ago, glad you did some calculations, hopefully I'll have a patent before part 2 video,apparently its easy approval for a provisional patent with a animated prototype internationally today.

10:21 in Y configuration the the end point voltage will be indeed sqrt(3)*fase_voltage, the current will be devided by sqrt(3). So the power will stay the same and not be lower like you mention in your video.

recently i made a ultra sonic radar without servo motor (with dc motor)! Are you able To Explain How I Calculate Angle?

Soon after the German word in 9:16, the BLDC went into hip hop dance with that 3d printed adapter 😂

Thank you for inspiring me. I will change my future nearer to your current path, may it be AC or DC. The next discussion should be about cheapest and effective alternative materials for all parts? Casting techniques will be the last step? The dialogue will be much more interesting. Kudos from Malaysia.

Great video! thank you for sharing.

Great as always! Nice video

excellent video coilwinder extraordinaire!!

Great!! This video and the previuos one are very good and usefull!! :) probabily can help me in future project. Just for curiosity: use BLDC (or stepper) motor as generator to provide DC will also decrease the efficency, because the output current (the currente that charge the capacitor) is only peaks and the bridge diode will no conduct for the overall period of the sinusoidal output voltage.

I am thinking of using an old manual grinding mechanism as a gear box.It increases RPM tenfold and is lubricated, has low friction losses.Thanks for the excellent video.

Hi GreatScott! Can you make a video where to explain the benefits of the brushless motor as a generator? I want to know the voltage and its power. Can this be used as a battery charger for example?( Off course with all the equipment needed)

Brill video as always !

You can get automobile or truck alternator rectifiers which are 3PH and Schottky very low drop,and current ratings from 40 to 250+ amps. Brushless motors can come in very large sizes, replace the bearings with Hybrid Ceramic to prevent current loss through the armature and eroding the bearings.

10:16 configuring either wye to delta doesnt change the output power. As the current decrease the voltage increases by the same factor. Wye to delta only changes current or voltage that is needed for some application.

Sehr schön 👍

Great Patience man :)

Amazing! Good sharing!

Can you bring back your versus series. Maybe do one for power supplies. A generic chineese one and quality one (Meanwell etc). Do tests on them (overload, max temperature and so on) and a conclusion if its worth the money. Also keep up the german humour in your videos. It always cracks me up.
