The lack of cogging has nothing to do with what you said fyi. This is known as a coreless design it w Has no iron cores in the coils.. also known as a "nonmagnetic stator" if you short all the windings and spin it you will feel some cogging from the current generation. While coreless motors and are nice they are much less efficient at capturing magnetic fields and turning it into power..
I did not know that! Thank you for the explanation. However a coreless design would allow it to spin up in even the weakest currents providing mA. Additionally based on the power density of the medium I don't think a cored design is necessary.
@@JoeMalovich the efficiency at low speeds is better but it reduces peek output by as much as 40% but the advantage is you can make power with at very low flows.this design is good for the setups like yours. The sown side is the narrow power band a coreless might capture 0.2watts up to say 250watts where the same size unit with iron core might capture 50 watts upto 750watts so it really really depends on what your working with if you don't have the flow to maintain the 35-50watt minimum to keep a cored stator from stalling then the coreless makes sense if your making 200+watts all the time then a cored stator will get you more power. All my figures are made up as an example and depend greatly on the flux density calculations and Eddie currents in 0.01in steel laminations used in most pmsm motor technology. I'm working on a completely new way to capture power from things like this that can restart it self and uses the generator itself to boost output voltage.. I have a working prototype controller now on my 750w windmill and if i compare my old mppt controller to my custom controller I capture around 65% more energy on average 😤. I simply applied regen braking and ABS concepts in a large modified hobby ESC with a software based mppt tracking the fact it's a speed controller means i can drive it like a big fan. But it's not really setup to do that it's basically trying to find a minimum rpm needed then pulses the brakes builds voltage in the stator using the flyback effect then dumps that back to the battery bank because of the it's a constant RPM variable torque system this mean with higher wind it just brakes harder to maintain rpm and thus more power.. also make a runaway almost impossible unless the mosfets fail. A big 3 poll relay and a small arduino act like a tach and watch rpm if it hits a red line it ties 6 10ohm 50w resistors across all the windings.
@@JoeMalovich I'm not really a content creator, the company i work for has some rules concerning engineer's having a social media footprint. Like most government contractors do. But I'm going to start manufacturing my new wind/hydro charge controllers soon and might need a test case so if you can email me some shipping info i will send you a prototype, but i will need to know what the max open circuit voltage you see on your generators. It will work wih just about any 3 wire brushless generator. And I'm adding a startup function for ASM motors but will require an external rpm sensor this will let people use ots 3 phase AC motors that don't have magnetics by watching rpm and using a cap to pulse the leading phase angle but still testing this on the bench..my username is my g m a i l. I have been watching your videos going back to the water wheel lol
Thanks for the video. Would love to see what it can actually output / charge when hand cranking at an average human rate. Also guessing the drill concept could be transferred to a bike application.
You didn’t show a closeup of the output on the watt meter, and you didn’t discuss it. If I made this video, I would have discussed what the output was as well as provided a close up of the meter. It strikes me as odd that you didn’t even think of that.
This has me thinking of my old bicycle generator! It rides on the outer edge of my bikes tire to power my headlight! But yeah, pretty cool brother! Also has me thinking of Ceiling fan motors & auto alternators !
Yeesh the comments you people post without thinking and without taking 5 seconds to search, which, if you had, you'd find multiple videos with what you're asking for, and almost all of them conclude that this is a good idea but doesn't create enough power. This video is needed and brilliant because it shows the upper limit of what this generator can do in PERFECT CONDITIONS, which you're unlikely to encounter.

@@ZoeyR86 I just looked though your videos and sadly could not find one on what you've built, I'd definitely watch one if you did.

@@ZoeyR86 is there an update on this build of yours? I'm curious to learn more about this
Very nice review, breaking apart.
Thumbs up from Montréal
Thanks for the video. Would love to see what it can actually output / charge when hand cranking at an average human rate. Also guessing the drill concept could be transferred to a bike application.
looking forward to the lathe test! thanks for the quick follow up!

I want to try building a gravity battery with it.
Pretty cool, would be fun to test it out sometime! Keep up the interesting videos!👍

you can remove the rotor and reinstall it with the screw bosses pointing upwards. for generating (without water) it makes no difference
you could try the lathe or piller drill
Damn dude. You are a genius and I just thought you were making a water wheel. Question? Are these worth the high price?
I think they are only worth the price in specific applications
had to dig to find the output of this thing.. makes me suspicious.. they certainly dont lead with that info..
Try a dremel!!!!!!
I don't see what the point of this test is I would want it to be tested in a creek or with the fan or crank adapter I don't see what the point is

Hi
Though not extremely powerful, be careful people because one amp can kill!
Eric McGinnis well said!
very low power can easily kill in the right places. one amp is pretty dang amazing
@@crackedemerald4930 What are you all talking about?
@@vaskylark electricity
@@crackedemerald4930 lol Well yeah I get that but the kill talk I don't.
How does it so in low wind?
It barely get 5v 0.1A in water (so 0.5w) and barely nothing in high wind.
