Вставка
- Опубліковано 25 сер 2024
- Homemade brushless outrunner go-kart / mini-buggy with full suspension draws 15kW at full load. Quick look over and some footage showing how it performs.
It was designed for mild off road terrain, and tight technical tracks.
Some Specs:
-Motor: 120100 model which is a larger version of the well known CA120 used on RC planes.
-Traction Battery: 24S2P turnigy lipos (88.8V nominal, 10Ah)
-Controller: KLS96501-8080I model manufactured by Kelly Controls
-Display / Logging / Control: MoTeC C125
-Peak Power: 15kW and above
-Top Speed: greater than 80km/h
-Range: 8km ish (driving it hard)
This project has been a while in the making, and isn't finished yet. There are a lot of aspects to the build that ended up becoming projects in their own right, such as investment casting throttle pedals, making a module to adjust hall sensor timing etc. I have several ideas for future videos.
This is my first electric vehicle build and it posed more challenges compared to the petrol powered go karts that I have played with previously. It also cost more to build than the petrol equivalent, but it has been enjoyable. I was inspired to build this project and share it with you by people on sites like UA-cam and Endless Sphere (where the focus is on electric bikes).
Thanks for checking out my first video!

Finally I found exactly what I want to build. Can't believe there aren't more of these on youtube.
Holy shit i Wanna build this too but with a honda gx and kart tires to drift more🤟
@@kevintimmermans4886 I think you're missing the point... the total weight of the whole drive system in this kart is roughly 13kg (4.5kg battery, 4.5kg controller, 4kg motor) and it can produce peak outputs of 25kw or ~33HP. Even the largest and most powerful GX (390) will struggle to put out more than 10HP peak and it will weigh in excess of 40kg with a fuel tank and clutch. Making the drive system 3 times heavier and 3 times less powerful seems like it would be a lot less fun and result in a lot less drifting ;)
@@opcolu vesc 100/250 would be much lighter than kelly and produce same peak power and make drive system under 10kg
That dog brought a smile to my face. He's having as much fun as the guy driving!
Such a perfect build! Thats exactly what i wanna build myself..
WOW! That is one kick-ass go-kart!!!
Wow. Nice Build! I'd love to see more details. I've started my own electric motor go cart project. Just bought a donor frame and now I'm looking into power train ideas.
when I imagine heaven...it looks just like this!
Thats looks fun 🤩
dude holy F thank you for putting this on UA-cam
Golly!!! That shit is fast!!
Well done sir... That thing really moves! This really gets me thinking...🍻
amazing meng, congraturations
Awesome !
we need a update on the kart !!!
That was awesome!
really nice build! looks fun
This is my favorite EV build. Lightweight, fast, and fun. Did you build that trailing arm suspension from scratch?
hey, how do you charge the lipo accu ? individually or all at the same time?
I looked up the motor that you're using and the website says that its peak power is actually 25Kw!! Crazy to think that you could go faster with a different battery arrangement.
Awesome build!! Curious how long your battery would last?
It says in the video 8km
Can this motor do 100kmh on slicks with a 50kg person, with at least a 100kg chassis
trying to figure out why you chose the kelly over a powerful rc esc ? was it because of the hall effect throttle , the programability, reliability, or some other reason im missing?? awesome insane build either way!
Great jpb and you should have more thumbs up , but i notice there isnt 1 thumbs down so that shows you did a great job .....👍👍
you just got yourself a sub
i want to build this myself i might upload something like this too
I just built a go kart with the same motor. Do you have the 3d printing files for the cooling duct? Also what brushless motor did you use for cooling?
Hi ! just want to know after all this time how the kart is doing. Did the motor survive ? Want to build the same, but i'm scared it won't last long.
What gear reduction are you running on that? 80kmh top speed is pretty good considering it looks like its got torque.
How do you make it go so fast is that because of the battery or tell me what what else
You used an air cooling instead of water cooling , right?
What kart is this?
I wonder how longer does it takes to shut down?
You living in Napa CA?
Hello, how did you fit the pinion on the motor shaft ?
Is that particular motor sensorless like other smaller rc car brushless motors?
How do you go about charging all the lipos??, the what KV?
The Batterys have 100A continuous and 150A peak current... not 200A continuous ;)
Hi can you leave me the link of the motor and batteries?
How is the motor holding up?
Did you make the music? I like the riff but it needs production
Yes, I put it together rather quickly for this video and I do agree with you
Nice build. How is acceleration with that motor? I am wanting to do a 96v conversion on a TAG or maybe a shifter kart if I can find one cheap enough.
Cheers! The big issue with the motor is cooling, I have put 250A through the motor and acceleration is more than 0.4g from 0-50km/h which is great but it wont sustain that. With well set up cooling, it should be good for about 150A continuous. I should do a video reviewing the motor
@@torquesynthesis7641 I would really appreciate a review of that motor. Before I saw your video I was going to do a dual motor setup using 2 me0909 motors with a split rear axle and run them in series @96v 300A max or parallel @48 600A max. But those motors are only good for about 30nm and 4500 rpm no load speed. These motors are about $100 🇺🇸 cheaper and according to what I have read 46 nm and up to 8000 rpm no load speed. So now I am thinking 96v with dual 120100's run in paralell. With 2 of them in paralell maybe I can run the pair at 300 or 350 amp max and still get the desired acceleration with out cooking them. Can you run a pair of 3 phase motors in paralell with one controller, or will that mess with the hall sensors? A respectable top speed would be nice but not as important to me as making it scary fast from 0-60kph (40mph).
The 120100 would probably struggle with 100A continuous with no forced air cooling - it really needs help keeping cool on a go kart. The 2x me0909 would be capable of higher continuous output than their specification says if you could add some active cooling. I suspect the quality of the me0909 would be superior and the specifications would probably be more conservative regarding power output, compared to the 120100.
The only way you can run 2 brushless motors off one controller is by running them synchronized e.g. on the same shaft.
@@torquesynthesis7641 Well that is discouraging....hahaha. It sure looks impressive on your machine.
Awesome build.
I see that you run a direct drive. how much is the gearing to the back wheels?
Do you know how much torque it produces?
Thanks! Gearing is 3:1. Motor torque is around 25-30 Nm, depending on motor current settings
@@torquesynthesis7641 Hi Torque Synthesis.
Super thanks for the answer.
In current building a dirt bike with the same motor that you are using.
So I just wonder how you have set up your front sprocket to fit on the “small “12mm motor shaft.
My project have just begun and Im waiting for parts right now.
Would be super cool to see some videos of this awesome creation.
Best regards//Axel
@@axelwiberg2068 The sprocket is welded onto a little hub, which then slides over the 12mm shaft and is bolted onto the threaded holes in the end of the motor. Thanks for the encouragement, I do need to make some more videos happen!
@@axelwiberg2068 hello im very intersted in your project any uppdates

What are the motor specs? What company makes it?
120100 brushless motor, produced mostly by Freerchobby, Flipsky & Maytech. It’s the same design with all of them, aside from various modifications each company makes to suit their quality control. They are possibly all built by Dongguan Freerchobby Co Ltd. but I’m not exactly sure.
The specs vary on a few things like kV (of course) and rated torque and max amps are slightly different depending on what company is giving them. Typically the specs are:
kV: 33 / 55 / 80 kV
Maximum Series: 20-27S (72/84V - 99.9/113.4V)
Max Amps: 300A
Max power: 25kW
Weight: 3.9kg
Rated torque: 35-46Nm
Nominal power: 10kW
Nominal Amps: 180A
Actual size: 120 x 180mm
Shaft diameter: 12mm
what is the input voltage for this motor?
and nice video!
The maximum voltage for the motor is specified as 100V, which the batteries are nudging when freshly charged. Thanks!
Hi! How long does it takes to unload this battery?
To physically remove it from the go kart? Probably only 5 minutes or so to remove both sides of batteries
@@torquesynthesis7641 Damn, sorry, my english is not perfect haha. I mean how long does it take (driving) to "make" battery empty :D
@@Oelngatikameie @3:39 8km
You're too tall for such a small vehicle.
Awesome. Horrid music.
If this riff had decent production, you would like it
