hi, I would like to make a generator. I have a 4-stroke 3hp grass cutter engine available ..which electric motor do you recommend using? how many watts can I squeeze out?
@Toys for Watts. I searched your channel and didn’t find a video for the finish the of this. Did you not finish this generator? Or am I overlooking it?
I have not gotten around the part 4...I had thought I would work on it this summer since it's traditionally "not windy" here in the summer, but it's currently 145 degrees in my shop :/
You're welcome! I think it only works with your phone if it has the TRRS adapter plug(included) You night need to try a different recording app too. I'm glad it works with your GoPro.
Turns out the Moto G5+ doesn't support an external mic on the hardware level...can't get around it as best I can tell :/. It is a bummed because I like the footage I get off my phone, but it's not easy to use when doing most of my recording outside or if I'm doing something that's more hands on. Sounds pretty good with my GoPro, though, and I use that more outside. I REALLY appreciate it!
In general you want the air gap to be as small as possible. The further away the magnets are the less efficient the generator will be. You have to make some concessions, though, because in flux the wires can wiggle and as things heat up and cool off expansion takes place...tight tolerances make it more difficult to assemble and more likely the magnets might introduce themselves to the coils at high RPM. I generally err on the side of lost efficiency rather than risk the consequences of a high speed internal impact.
@@ToysforWatts Thanks, but I was not asking about that width. I'm asking about the size of magnet, eg a bar magnet 40×20×5mm Vs 40×10×5mm passing the windings,
GREAT WAY TO GO WITH ANY AC MOTOR ROTOR . WOULD BAR MAGNETS WORK TOO IF THE HOLES WERE LONG ? LIKE TO SEE THE OUTCOME ALSO . MAY THE SOLAR BE WITH YOU .
Bar magnets work great but they require that you either slot the rotor or mill the whole thing thing down. They're a great way to get a greater volume of magnet material in there. These round pucks like I'm using will work, but the ease of conversion comes at a loss of potential and efficiency. Blocks and cubes are the best way to get the most possible out of it. This one below was made by a guy who goes by "Sparweb" and he's built the wildest conversions I've seen. www.fieldlines.com/proxy.php?request=http%3A%2F%2Fwww.sparweb.ca%2F3_Gen_MoCo%2FBaldor%2FAssembly%2FBaldor_Rotor_Last_Mags-s.jpg&hash=293125ec38fd66295fa2e6ad0b98854d82c3d7ee
The iron core of the rotor will induce internal flux when the outer winding have current passing through them which will rapidly increase the load on the generator. The core must go.
Yes and no. What will be The Problem here is the 'Squirrel Cage' inside the rotor. It is the very heart of, and how, an induction motor works. You can see its end plates as the circular silver coloured ring at the ends of the rotor. Those rings, one at each end, connects together all the bars of the cage buried inside the rotor. Usually made of cast Zinc metal That squirrel cage if left intact will induce immense drag on the generator - it will effectively kill it. You have **GOT** to get rid of the silver coloured rings from the ends of the rotor - otherwise you're gonna finish up with a glorified electric powered heater..
I had the places I needed to drill marked, a paper template wouldn't have helped drill the laminations...kind of a fools errand all around with the cost of doing this versus a direct drive washing machine motor. I'm going to be revisiting this project but going a slightly different and more serious route.
@@ToysforWatts understand. Hurry and do it, the maintenance guy at work offered me a 3 hp motor. I noticed some place magnets perpendicular to the shaft while some angle. I can see the angle giving a longer pass by the coils but does it matter? Thank you for showing and telling us. This is very interesting.
Placing the magnets at an angle smooths out the flux...reduces the cogging. My parallel to the shaft it is the more cogging there is, but the cleaner the magnetic field will be (more efficient, more power). Makes it harder to start. You can angle the magnets, which reduces efficiency and output, but makes it to where the turbine can actually start. It's a balancing act, though...too much and it kills the field. Usually if you don't know for sure then keep it straight or don't go more than 5~10 degrees. When I come back to this it'll be straight bar magnets, no angle.
@@ToysforWattsthanks, yes we're doing this for power. Agree on the bars, stronger magnets more bang. I like how this guy does it, he's got it down. Apparently he does it for a living. He doesn't speak English but his work says it all. ua-cam.com/video/1-LKxVhPDOE/v-deo.html
They can but heat in the magnets likely won't cause a lot of trouble. The coils can get pretty warm, though, and that can cause damage if they get too hot.
@@ToysforWatts I comprehend completely, I'm just asking because seems that you invested in others projects to generate electricity by motors or dynamos (whatever you prefer to call), I am also interested in them, but I'm curious a lot about this project because in another UA-cam channels which tried similar ideas didn't get effective successful generation and I still want to find out why. God bless you!
That's going to be an ambition project and to get the most out of it you're going to need a lot of milling and machining and large, very powerful magnets. I would highly suggest you hit up the fieldlines forum. There's a couple guys there who have done some large induction motor conversions...not that large, but still pretty large.
@@ToysforWatts I'm starting with 22kw motor. Rotor diameter 8.3"... I'm gonna put magnets on it and to match poles of windings. You didnt matched. You made a gap. Other thing, which I guess you know, we can produce power from not modified induction motor. Need to connect motor run capacitors parallel in phase. Example is here m.ua-cam.com/video/K4XAEsUvUZ4/v-deo.html
@@BOREDANDWELLBORED hey, I already made my 22kw generator powered by vw 1.6D engine. I Don't understand what positive negative you talking about, when we do three phase AC motor where are three phase wires 😸😸 Or you decided to make DC generator? In that case choose DC motor with + and - 😸😸
@@Boteris watch this video, ua-cam.com/video/-kZ9u-a3-0c/v-deo.html. there's 3 wires, he only used 2 for positive and negative and ignored 1. How did he know? Some AC motor wires are not color coded.
@@ToysforWatts so I've watched hours of videos about turning washing machine motor to generator by adding magnets to it. The only issue to me is the 3 wires sticking out, these Indian guys make it look so easy identifying which one is negative and positive meanwhile I'm losing hair trying to understand how they know. It's not color coded. If you have a answer for me my hair may grow back thick again.
@@BOREDANDWELLBORED Okay so this is the really important bit...there is no positive/negative with the washing machine motors. They produce three phase AC current. You need to run all three wires through a bridge rectifier to change it to DC to charge batteries. I'm linking you to the bridge rectifiers I use below. If you go to my profile here on youtube and hit the playlists tab there should be a whole collection of videos on converting an F&P/Samsung direct drive motor into a turbine. www.ebay.com/itm/233421540058
@@ToysforWatts thanks for the response!!! I'm not trying to charge DC batteries. See this video ua-cam.com/video/gcx1Yi67Jh8/v-deo.html. He used 3 phase washing machine motors with 3 wires sticking out in the back, he ignored 1 wire and connected 2 wires to positive (hot) and negative (neutral or "0" whichever you prefer to call it) to power multiple AC appliances. My question is how did he know which one goes to "positive" and "negative" wire? Yes there's positive and negative in AC outlets, you may call it "hot, neutral, zero, Aquaman, spiderman, etc" however you prefer to name it is irrelevant, you can call me asian, Filipino, brown, short, etc doesn't matter, what matters is I exist just as "positive and negative" wires in AC outlets exist and I need to know which 2 of the 3 wires are "hot" (positive) or "0" (negative).
I hate to say it but I simply have not had time to come back tot his yet. The magnets I got for it didn't fit very well so I'm going to be looking at a different magnet arrangement...I will come back to it and I'm going to try and get to it this year!
@@ToysforWatts Nice, could you try generating power without using the magnets and only a capacitor, with the same kind of motor? There are videos on youtube on how to do that.
You absolutely can! It's even going to save you some headache since you won't have to cut the rotor up and glue magnets to it! They're generally ready to be generators right out of the box, though you might have issues with the voltage being too high on some of them.
I haven't come back to this one yet...it's sitting on the shelf. I have all the stuff to assemble it on hand (I think) but I've had more pressing projects. It's something I'm going to come back to once I get my workshop back under control.
It's unfortunately sometime after all this COVID stuff passes and I get to go back to work full time. I have to pay for all these projects out of pocket and right now project money is tight. I hate it, too, because this one basically just needs epoxy and a rotor (I'm thinking some variety of VAWT), the i1500 just needs some mounts made to tilt it back up, and the Heli all I need is a piece of 3 3/8" OD pipe to convert the stub tower to take the turbine head. All seemingly little things but just hard to do right at this moment. Hoping things pick back up very soon.
@@ToysforWatts is there any chances that this can be used to generate enough electricity for a decent electronic device, at all? or is it just enough to light a few blinking led?

Other projects took priority, it's still sitting on the shelf waiting for the time and funds. I think when I go back to this, though, I'm going to ditch the button magnet idea and just have it turned down to fit real magnets. I wanted it to be a simple "anyone can do this" kind of build but honestly the cost of having a machinist turn it down is pretty negligible and trying to do it with hand tools is simply not going to get good results.
That's a lovely convertion!!

Instead of one magnet per hole can you use 2 or 3 thinner ones,
