Can I Power This Go Kart with a Used Car Alternator? 

Reminds me of ElectroBoom

@@oli_g_98 Got the exact same impression, its the careful balance between making sure all the important information is conveyed, but not making it too complicated and understandable for any kind of viewer

Clearly he forgot to carry the one for calculating the HAL sensor position.

Seriously, this was some Technology Connections level stuff. Very impressive!

ssshhhhh just go with it

Yeah cause they are in the front!

The yugo is sick tho

xD

Lol even the smallest ones were 0.9l.

4hp? You're seriously overestimating the Yugo

No, the Trabant. The Yugo is 3

No, that's 1116cc 52 horsepower. His is a 1.5 with closer to 100.

@@jm036 Yeah, only Europe got the 900cc OHV 44hp engine though

I read this exactly as he was saying it strange

I too had a good laugh at that comment. Brilliant.

​@@Thefreakyfreekfucking same thing just happened

She is likely overwhelmed with excitement by your epic build. Stay epic my friend!

@FlintsYT Was just making a joke friend. Wasn't being critical or sarcastic. Great video btw. I've always wanted to build one, just never had the time or the workspace.

Go get it done!

It is said that i never know when to quit. I say i just never quit. We might retreat today but the fight is Not over, the battle might be lose but the war isn’t over.

Finish it

The one in the middle is linear?!?! I noticed it has a different designation but the output signal was still a sharp square pulse...

@@TheOriginalEviltech only some of them use linear type in the middle, most of those hub-type motor just use three same switch type sensor, with variants that have the middle one facing opposite of the other two, as you've noticed

@Lassi Kinnunen 81 That makes no sense, 3 inputs means 3 sensors.

Very good point with hall sensors, I almost forgot that there is enormus types of hall sensors (analog, digital, latching, non latching, 3pin, 4pin, different voltages...)

@Lassi Kinnunen 81 He only installed 3 sensors, which is correct The other issue I've observed is that he gave the whole system a fairly small final drive ratio, while this controller is mainly target towards direct-drive hub type motors. Those motors are commonly seen in light electric bikes, and I'd imagine if he raise the final drive ratio to about double direct drive rates, the go cart can start rolling by itself with no problem.

I love how he uses the electric go kart thing as an excuse to play with making a home made electric toy

David. The first thing you should tell him is, if he takes a Delta connected motor and changes the configuration to a Star connection it will make the rotor twitch because the Rotor is wound for a Delta signwave. If he changes it back to a Delta connection it should work.

@@briero sure that title already goes to the bus.

High school science project.

@@KillroyWasHere86 of his grandchild

Amen to that 😆

Thats exactly what I was about to suggest he do, is wire in a start capacitor set.

But he also could blow the lipos if he doesn't have a safety feature for when they get discharged too low. I've seen crazy guys just use a lipo voltage checker and stop using the application once its low 🤯💥🪦⚰

@@jiffywaxjesus1951 agreed...thats a good point you bring up.... definitely gonna need a ESC with voltage cutout....the new EZ-GO golf carts use voltage cutouts on their speed control...he can incorporate that into the loop, he'll be set.. Definitely dont want them going bellow 3.3v..

Pp⁰p00⁰⁰

@@jiffywaxjesus1951 I believe that’s why he used the riobi battery because they have circuitry to shut off the battery’s when they are too low

I was afraid he was going to use a Coda motor...

The Wheego battery is dead, remember? All the LiFePO4 cells failed. Also that motor can accelerate a car up to 60 miles an hour, that child will blast itself into a tree so hard it will become wood.

He wants the go-kart to run.

oh geez he made something with a higher build Quality level then the wheego muhahahahahahahahaha

@@alfwok hey if he wants to build it himself let him not everyone wants to buy everything some people like to build and tinker

I'd have just bought a new engine from harbor freight. They are basically clones of Honda stationary motors

@@nubreed13 nothing wrong with that but some people love to tinker

@@raven4k998 yup for video purposes this is totally fine

with parts that were all Chinese how interesting

Only without a phone-in description of a Gremlin . . .

A vicious slur against the designers of the go-kart. For one, the go-kart is way better looking.

Nah, I suspect that this go-kart conversion involved a lot more nuclear engineering to optimize magneto-reluctance and capacitive diractance.

You mean Tesla ?

Have you tried turning it off and on again? This is a joke in IT support, but it's also the most common advice. Because it works 90% of the time. Bloody programmers can't write software without memory leaks, or that gives back resources the computer when it's finished using them. So then when another program, or the same one later on, need these resources, they're not there. If it's RAM they've consumed and lost track of (a memory leak), eventually the system will run out of free RAM and start swapping out to the hard drive, causing thrashing and slowing things riiiight down. So we'd ask you to save your work, if you can, then shutdown and restart. On restart the RAM allocation list is nice and free again, resources are fresh and unallocated, so programs can ask for resources and expect to get them. Everything runs nicely! Except there's still that leak...! The solution ultimately is for the company to fix their damn software and for users to update to that version. But in that time there'll be a _different_ bug in that, or some other, bit of software.

Software devs are the bane of my existence. Last timeI had an issue I sent 140 GBs of data to one of our software engineers to back up my claims because a control program they had us upgrade in the field had a huge memory leak and would corrupt it's own config files. His reply was, "Huh, well it didn't do that in our field trials."

@@NORMIES_GET_OUT as an engineer I can tell you that when we design new things, shit always happens. I spent months working on the binary register of a microcontroller to be able to manipulate multiple dc motors. It worked PERFECT up until installed in the machine. Then EMF from the dang motors caused it to auto trigger since I was using such “basic” components of the controller!! We try, we really do, I am also a mechanic of 20 years so I know the pain of a terribly placed bolt (just as my engine mounts smh) But it still just happens. And most of us are (probably) eternally sorry!!

@@TGears314 aawww man. and here i was thinking that every terrible placed bolt or stupid ass system (or function within a system) was put there on purpose by a very bitter human behind a desk, dedicated to the missery of others. like "ok.. we need a bolt here, here, and there. you know what? fuck it, i havee a terrible day... im gonna put it over there so someone someday somewhere will curse until hell opens right bellow their damn feet". :P

@@NORMIES_GET_OUT AMEN, AMEN, AMEN!!!

And 1500W is plenty. Even for a big guy like Aging Wheels. Although it is a Chinese 1500W…

@@mondotv4216 who would have thought that exchange rates apply to wattages, and not just currency.

The BMS is cutting it out why? They can put out more than enough current to move that go kart without anyone in it. It's immediately cutting out, and definitely isn't drawing anywhere near enough current to trip over current protection.

I suspect the controller is cutting out because it is not a 36 volt controller (yes what he has is claimed to be a “40 volt” battery, but every one that isn’t marketing considers 10s to be 36 volt). The resting voltage is high enough that it doesn’t fully trip the controllers low voltage function but as soon as the battery sags the controller cuts out. It’s likely a 48v 1500w controller. It’s actually not common to find a 36v 1500w Chinese controller.

@@crispysteve42 from a pedagogical POV, quite likely ... but for entertainment, it might be a smidge less likely (or require far more creativity than the wasteland that is my bean tin of a brain can muster).

Just get the wheego running again and he can use that

you would save more than $5000 in the long run not caring for the child

What he should do is ditch this dumb idea and put the damned engine back in it. A simple limiter on the throttle will solve the power (of a 6yo) problem, just like they do with go-karts in those go-kart rental places. I subbed to this channel back when he was rebuilding the Trabant engine. Taking a great gas powered go-kart and turning into a shitty electric cart is just dumb. Trying to convert an alternator into an electric motor for the kart is DUMB. I already knew he was going to run into all these problems because he's not the first youtuber to discover the problem of re-purposing an alternator. Furthermore, this thing is designed for a maximum of 65 amps output or about 900 watts. They are notoriously unreliable with high load.

@@tarstarkusz I guess you missed the part where he said he was doing this for the fun of it. He wanted to do the thing. So he did the thing. If you came here to watch an expert with all the answers do the most efficient and effective thing, you've got the wrong channel (and website, for that matter.)

WE GOT ENOUGH RU-vid VIDEOS WITH LOUD, UNNECESSARY MUSIC.

I was quietly screaming this in my brain the whole time

I wrote this in butter on my toast this morning

you only know rotor position within one electrical cycle (phase). you still don't know the exact position of the rotor itself as there are multiple electrical cycles per revolution. also, the "idling" phase statement is only correct for block-commutated/six-step drives. Sinewave and FOC drive all 3 phases all of the time.

In Permanent Magnet Synchronous motor (PMSM) drives, shaft position information is required for the proper control of the machine. In the PMSM drive the torque ripple generated by the machine has various harmonic content. The major torque ripple generated in a three phase machine is due to the interaction of 5th, 7th , 11th and 13th harmonics in the back emf with the phase current. These induced voltage harmonics are responsible for the 6th and 12th order (electrical) ripple in the torque. In practical applications we tend to see various other harmonic orders in the torque.

@@brianginn6354 me too

what size would he need? 2f?

@@ExplizitDuester honestly idk, i just know that most Three phase commercial motors have start up capacitors to get them moving

That was my first thought too!

Well, on the plus side, at least the comments are full of people griping about the title. The content of the video is fine. If you don't like the title, dislike and move on.

That bothered me too 😂 - they are supposed to sum to constant power deliver.

Same thing here

can's believe it either.

He removed the CVT when he took off the gas motor. It's direct drive now.

It's not direct drive, it's a single speed transmission.

I assume the drawing was just a crude illustration but you are absolutely right, it was not 100% correct. My OCD screamed in my head too.

YOU ONLY HAVE ONE ISSUE? Your kidding, right?

@@imaetech9648 I was a commercial electrician who dealt with 3∅ power quite a bit. I deeply regret not going through the video frame-by-frame and pointing out all the technical problems I don't really know much about instead of pointing out the obvious thing that stood out to me; please forgive me. I'll do better

RC cars have sensor less brushless controllers. They're designed to operate without the hall effect sensors, so it's a bit different.

@@zakattack721 his motor was sensorless he added the sensors because it wasnt moving just twitching

@@compzac Yes but the controller was expecting a sensored motor. If you unplug the encoder on an eBike it fails to spin in the same way

@@zakattack721 was it though, it was working better before he sensored the motor... really my guess is that the poorly translated sticker on the controller and the non existent manual would have told him how to set up the controller, but since the manual doesnt exist and the sticker on the controller wasnt in english how would he have known it probably needed to be programmed. most controllers ive messed with can use either hall effect sensors or back EMF but you have to tell the controller what to expect and in some cases have it learn.

@@zakattack721 my god I didn't realize RC car motors were sensorless even you really have pointed out the obvious there chief

On a side note, i would love to get that gasser motor from you, i just got a go kart for my nephew and the motor, while functional, is a massive 8 horse motor

@@jaquecole5196 Given it cuts out, and given shipping costs... Harbor Freight sells a 79cc 3 HP horizontal shaft motor for about $130. Might be an easier, faster, warrantied option for not much more expensive.

@@DTXBrian perhaps, but i like older engines better and part of the fun of the problems is solving them

@@DTXBrian I would rather have a seized Briggs than a brand new Harbor Freight time bomb

@@jaquecole5196 older engines... that engine isnt old enough to be considered old since small engines really havent changed in 20 years its going to be either a tecumseh or tecumseh clone, or a briggs or briggs clone either way its really not different enough to be unique, also he wanted to do this as an odd project the end result he was slightly expecting it to not work brilliantly, it wasnt the end result he was looking for it was the fun of doing it and i sorta appreciate that, watching old small engines is fun too, thats why i also watch mustie 1, but for some interesting idea using a cars alternator to try and make an electric go kart sounds so much more interesting than cleaning out a carburetor or replacing a coil.

Also a relation to warped perception?

As Elon Musk has so scientifically pointed out, if humanity does not become a multi-planet species, the risk of us just ceasing to exist, from a single catastrophic event, is at its highest. The more spread out we are, the more likely we will survive as a species - regardless of where we are.

@@jcpt928 and humanity survive is a good thing? :-) ;-)

Used the wrong cells then.

@@peterzingler6221 oh yeah for sure, not enough in parallel

ive taken apart 3 treadmills. they were all fairly high dc voltage (70-100). if you run them at lower voltages they overheat. maybe there's a treadmill with something different but i havent found it yet

Good ole Turbo Encabulator!!

See, This is where he messed up. Every seventh conductor is supposed to be connected by a nonreversible tremmie pipe to the differential girdlespring on the "up" end of the grammeters, and he obviously did not have the correct tremmie pipes.

@@phr3dmcc0y The motor also should have been mounted onto a Baseplate of Pre-Fabulated Amulite.

@@phr3dmcc0y Obviously

Totally agree with this. Just tossing any old voltage batteries on that doesn’t match your controller is doomed to fail.

@@americansforhire5378 yes it may could have likely might solve it- though it also may have fried his controller if this additional battery increase the voltage too much. The best thing to do is use a battery pack that is the correct voltage for the controller.

@@americansforhire5378 it’s possible. At least keep it from cutting out after 10 seconds

Have a property fenced in and roleplay communist germany!

it does have a fan, its inside of the case on either side of the rotor, most alternators do that from the word go because of heat, since they are usually attached to a big greasy heater anyway.

Ahhh...kinda like an air conditioner or a dryer?

3 phase motors dont need start capacitors like a single phase motor does

or the coil is failing... or theres another wiring issue causing a ground fault, or the carb is dirty... the most likely problem

Which is in fact already the job of an alternator in a car. You just don't get to choose when it is braking your engine!

Some newer cars switch the alternator off during acceleration and on during braking. Saves a tiny bit of fuel.

Plug it into mains maybe? Hahaha 🌈

Yea, try with 3-4 regular car batteries in series and thick cables to test if it works!

"Chrysler turbo encabulator" Funniest video on youtube

Since this comment was 2 years ago is there a better version of this available in 2023?

I don't think so. It's too low of a currant draw to do that. More likely the battery draw is more than they can handle are the BMS is cutting them out. IMO

It's immediately cutting out, and not drawing anywhere near enough current to trip any of the components. Not the batteries nor the controller.
