I know virtually nothing about electronics but you describe things in a way that's easy(ish) to understand. A lot of things you say goes over my head though but still it is enjoyable to watch. You speak English extremely well. You did make me smile when you called your vise a "wise". Thanks for the videos.
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.
@@ChristopherJones16 Why silver plated wiring? Same reason people gold plate wiring, corrosion mostly. Also in Aerospace you silver plate your wiring and other surfaces as it effectively stops dendrite growth which causes short circuits AND gives skin effect dampening from EMP for space based sattelites though gold is used usually.
Love the way your native language has ways of putting complete ideas, even processes into one word. @9:50 I see there's a word that you say on the Patreon page means the 6 pulse bridge rectifier, but similarly Schadenfreude, or even better, Backpfeifengesicht and Verschlimmbessern Interesting project, I used to make tiny motors for RC planes by rewinding the motors from old computer CD drives. 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.
Rule for watching Great Scott video. Rule 1: Like the video first Rule 2 : enjoy the video Rule 3 : after watching the video, think of what you're doing with your life.
Excellent job! Very informative and comprehensive video on converting a BLDC motor to a generator where the sample is an RC KV Motor. Thanks for this video as this saved me time and money from doing the exact same experiment to come up with the answers that I need where you have already able to provide. Keep it with these kind of informative videos.
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.
Oh good I'm glad I'm not the only one who thought that. Star has higher voltage while delta has higher current. The product of volt and current in both configuration is the same.
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
Great work! Thanks for this video - I have a brushless direct drive washing machine motor I wanted to use as a generator on a wind turbine, but it needs re-wiring. Your guide and links make me more confident I can make it 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 have a generator head from a old portable gas generator and my question is to you is can you wire up the generator head as a go cart motor? Instead of the gas engine turning the generator head and the generator head producing AC current, is it possible to introduce a DC current to the generator head so I can use it for a go kart motor?
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.
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.
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.
We love your videos, but please don't hurt yourself when you ask us to stay creative and that you will see us next time :) Scott, you are really great, stay like that.
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.
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.
Excellent video. I might share this with my students. It looks like you have created (3D printed) your own shaft coupler as well. Thanks again for your detailed demonstration.
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
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.
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.
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?
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.
also if you're having trouble with the adhesive just put the entire coil setup in some rubbing alcohol. it'll eat away at the glue/adhesive but not damage the coating on the wires.
Hi.... I would like to know more about designing motors and AC generators??...In particular, the relationship between wire size, flux calculation, terminal voltage, current per phase/ per coil and power output....Any recommended books or materials/websites....?...
Hi, sir I, am rewind the motor but I,m don't understand please guide me .motor dimension : stator diameter 28 mm and length 22 mm how many turn per slot and which diameter wire is use for this motor for 2600 kv and please tech me how to calculate specific winding for brushless motor .I,m waiting for your answer
Hello, what is th efficiency you got with this new wiring (new enameled wire, new number of turns, new star configuration)? In the last dc,bldc,stepping motor generator video it was very low
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.
Opinions on using a BLDC motor as a dynamo on a bike? I have a fast classic bike and want to give it a small lightweight dynamo with little drag and I wanna use a BLDC motor for that.
If you ever need a high voltage generator I can recommend a microwave oven motor that spins the plate for your food. I turned it and got zapped. I was like WTF. Than I measured the voltage and got 90V AC from hand crancing and over 780V AC with a drill set to the lowest RPM. My multimeter only goes up to 800...
Couldn't you replace the Sechspulsbrückenschaltung with an ESC, that has a hall sensor, knows where the rotor is and then activates the specific coils to let the current ggo backwards into the battery? Or in other words, how do electric cars recouperate? With a 6PBS or a special ESC?
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.

Very informative! Thanks for doing this experiment and posting. It gives me the data I need for a demonstration project I was having difficulty researching.
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)
10:12 power stays the same for either configuration. Cause P=U*I and both of these are either phase or line. Please don't mix up those 2 cause in phase 1 is devided by sqrt(3) but in line the other is devided by sqrt(3)

A 3 phase brushless motor has the following values. The maximum current drawn from the battery is 4.62 amps.. The thrust is 4025 grams with a three-bladed fan 18 * 8.. The speed at the maximum lifting force is 2780 rpm. The battery voltage is 23.46 volts. How much is the output power? How much is the efficiency?
Greatscott im working on an experiment that is currently on hold, but i would like to see if you can continue whete i left off. I would like to turn a stand fan into a generator by rewiring. Or a washing machine motor. I know if anyone cando it you can. Keep me updated.
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.
As the windings were actually several wires in parallel, could you rewire the individual wires without unwinding them? Unbundle them at the ends, reconfigure from parallel into series.
What about trying to make a DIY 3 phase generator. Would love to see the result and what you could power. Looking forward to the video if you do it. Keep up the good work👍
Sir i need help I want to make a circuit by which we can on and off relay by a single input If 1 input is given to the circut the relay gets in on condition and the 2nd input turns relay off
I think you could have split the original winding into parts, as they are all made from individually enameled wire. Like 2 parts of 13 litz wires and connect them in series. Of course after dividing the wires of one side into two bundles on the second side you have to test each of the 26 litz wires from the strand individually, to which part-winding it belongs. But this seems doable.

You could have also used a buck converter to get the desired >1 volt output, and would have been the easiest of all three options.
As the windings were actually several wires in parallel, could you rewire the individual wires without unwinding them? Unbundle them at the ends, reconfigure from parallel into series.
I think that is not feasible,
What about trying to make a DIY 3 phase generator. Would love to see the result and what you could power. Looking forward to the video if you do it. Keep up the good work👍
This is a 3 phase generator...
Love it! Learned something new today!
Awesome!
Amazing video, one of your best, thank yoi Scott 👌
Hey by converting star to the delta in a 3 phase system does not affect the overall power. 10:14
Sir i need help
I want to make a circuit by which we can on and off relay by a single input
If 1 input is given to the circut the relay gets in on condition and the 2nd input turns relay off
Hi,
Can you recommend some materials for electrical motor rewinding??...
In Delta configuration, where's the ground terminal of the coils?
Can you make 2 side speaker using single coil
Dear Sir, can you please help with the detailed explaination of the circuit diagram of a remote controlled BLDC ceiling fan?
Soon after the German word in 9:16, the BLDC went into hip hop dance with that 3d printed adapter 😂
I think you could have split the original winding into parts, as they are all made from individually enameled wire. Like 2 parts of 13 litz wires and connect them in series. Of course after dividing the wires of one side into two bundles on the second side you have to test each of the 26 litz wires from the strand individually, to which part-winding it belongs. But this seems doable.
