Hoverboard Hub Motor Modification
ฝัง

- As you probably know, Hoverboard Hub BLDC Motors are design to be slow in speed and high in torque. They are usually configured as a Wye (Y/Star) and this modification enables you to setup your motor as a Delta.
This tutorial is for who is planning to use Hoverboard Hub Motors for customised projects like 1WD, 2WD E-Scooters or even a 4WD E go-Kart where more speed is required. This modification can increase the speed as much as 3 times and can handle almost same torque.
Have a try! Worth it a lot!!

This is super awesome. I built a few hub motor powered skateboards. I haven't quite wanted to go faster than its max (13 mph), but when I do, I'm definitely going to do this. Thanks
Thanks mate. I’m glad that this project helped yours somehow.
Thank you for showing this process. I use my homemade disc sander powered by one of these motors. But I have to use a higher voltage source to get more rpm. I'll have to change to delta config if I want to use my 25v portable battery pack directly.
Bro you're great bro whole day I searched for this video finally I found you
I hope you can find useful info to help somehow with your projects…
absolutely fantastic job this help so so much
Thanks buddy. Your comment keeps me motivated to carry on!
Exelente video Eduardo, saludos 👍👍✌️✌️
Gracias amigo!
Cool! 😎
I have so many of this hoverboard motors laying around, now I am eager to modify one and experiment with it.

É muita inteligência. Parabéns, amigo.
Valeu Erikson! Faça o projeto! Vale a pena…
Buen trabajo. Tienes un nuevo subscriptor.
Gracias Nicolas!
mother of god .. !!! great project !!
Thanks mate. I need to improve it. Specially my videos. I’m planning to finish the e-scooter this summer…
nice video thanks for sharing
Thanks Mr Big Happy!
Very nice and interesting, hope you repeat the video with closer camera on the motor and more simple instructions for beginners like me. Thanks
With a multimeter and some knowledge on how to measure ohm or continuity, you can easily find the windings accordingly. I have tried to make this tutorial as simple as I could...
@@Attic-Toy-Design you have no sound. SMH lol
你好嘢！！谢谢你的视频分享-china HK
Great job thank you for that I had not realized the performance could improve that much it's as if you bought an expensive e-bike motor and I had no idea that those little things had that much potential hiding inside of there, but then when I think about a hoverboard screaming like that with the modifications it would not have been a safe hoverboard (not even close) it would have been quite the little death trap wouldn't it have? Wow, and a helmet just wouldn't be adequate for keeping someone from injury, you'd need a 100 lb. Full body chainmail bodysuit if you hoped to keep any skin LMFAO 😊😅😂
Thanks for the awesome video and a mighty fine demonstration of how knowledge and understanding Beats ignorance every time even with all the worthless paper rectangles in the world to throw at it when it comes to realizing maximum potential.
This unlocks a little secret for me because I had heard that Tongshen mid Drive kits in every tiar all use the same exact motor and now I know what that really means 😊 they're just configured differently and with the right modifications I can pretty much get the $1,500 one when I buy the $250 - $300 most basic one and unlock its potential.
You have a new subscriber
What a great comment Robert! Thank you so much. You are a kind of person that brings motivation to me. I will try to finish the e-scooter middle frame and sort out the batteries. My problem now is time! Let’s see what happens this summer…take care buddy!
thanks ill definatly have alook at this
Thanks Katie. It will worth it!
I watched few videos with this mod to understand whats going on
TO All who dont understand this : this is NOT delta , this is STAR configuration with parralel coils
before mod it was also star but coils were in series ,because motor controller works like a variable frequency drive it runs
slower without this mod , in essence youve just shorten the distance of wire , where u get 3x speed , bcs controller is same frequency , where youre exitacion is 3 times shorter, also current is 3x higher so u can burn out your controller or wiring ( find a controller for more current ). If someone wants this to use as a generator , this mod would only drop voltage by a third , but also increase current. FYI delta does not have neutral point.
To clear up the terminology the Y vs D connection does not affect rpm. This motor is a 30 pole 3 phase motor. As 30 poles the motor will spin at 200 rpm when fed 50Hz. This rewiring is reducing the number of poles inthe motor and hence the rpm increases, and the torque decreases.
So if you rewire and increase the number of poles it will increase torque? Maybe increase torque and use the wheel and a gear for a transmition for a small gokart or ebike
Put them back into a hoverboard and trick people into taking it for a ride.
yes please
Love your don’t be shy attitude I was very impressed. Is there any way you could make a delta interface so to speak a plug and play device that turns a star configuration into a delta? I feel the coil wires are so quantumly entangled it probably won’t work. I noticed these motors don’t take a lot of power and are tourque and throaty. Good job brother.
I'm guessing the delta configuration would produce higher voltage output, when the motor is being used as a generator? But, how much current can it generate?
and after you replace it on the hoverboard? and can we have the link of the green part?
Hi, for delta rewiring I used another method without cutting the coils. but the torque has decreased considerably.
Will I have the same torque problem with your guide?
analyzing the diagram you do not simply connect the coils in delta, but connect the blue coil, divided into 3 coils, in parallel and then connect them to Y
Wow
epic
hi. may I ask a question? so delta give more speed, but when speed is the same with one draw more current?
like delta has 1000 rpm and draw 3 amps
so I rewind it with Wye and it have same 3 ampe draw. so does wye config give the same rpm?
sorry for the dumd questions
Why do all the connecting wires need to be cut,can i just use the three soldered together wires that terminate in the star configuration and re connect in delta configuration,advice please
Hi. Delta is kind of 'parallel' winding configuration and the reason to cut the wires is to find out the right windings for the new delta setup configuration. The three soldered wires must to be removed to be able to make the new delta configuration. There is a drawing picture in the beginning of the video that is very useful for a reference.
another imposibile project 😢..thanks for sharing !!!
👏
if i use the foc control thats usualy for this motor in wye, can it work in delta? or will stuff notwork as calculations need to be different
somehow
I am using the FOC control as usually working in delta with no issues.
@@Attic-Toy-Design did you self tune the algorithm tho ? I'm using the foc hack for the original board . Altho I did find people that got it to work . But I also saw I can get 1700rpm with field weakening ajd foc on wye so... Il see but thank you for the answer
Cool. Can i just separate the 3 end crimp and connect them to 3 phase wire for more simple?
Thanks buddy. You need to follow the rule. The speeds of Delta are high because each phase gets the total of line voltage.
for people wanting to do this: NO, this is NOT delta modded, but a configuration called triple Star. a normal hoverboard motor is 3 individual coils, with 3 coils in parallel for each phase, so 9 total coil sets. normally, 3 in series for each, and 3 together for a y config. delta modding is much simpler than this method in the video, as all it is is you undoing the y configuration's center tap, and wiring all 3 main coil sets in a loop.
i will make a video at some point on how to actually delta mod motors, which is much simpler than this. however, i am currently messing with this method in the video and it will require INSANE levels of current to mess with, so you absolutely have to rewire the phase wires with higher gauge and temperature resistant wire.
give me link to your video ot some tut please :) thanks
I would love to see that video as well
That is exactly what I thought watching it...why cut each individual coil.
It is much simpler to just increase the voltage to go faster. If you use a ebike controllerr, most of them can actually run at 60v, so compared to 24 or 36, it would double the speed. You can also use a dc-dc converter to up your battery voltage from 36 to 60, I have some 1200 watt units I used on my ebikes for this.
👍👍👍😊
This is class I might try it how difficult was it to do ?
I think the challenge is to find out the windings correctly and identify them, as shown on the video. A ohm meter or any continuity test is essential to find out the windings.
Awesome video.. I'm new to these mods, given that even w/o any mods, I run my little hoverboard motor using a 52v battery and a 48v controller, and I get close to 35 Kilometers per hour on my ebike . needless to say the motor gets hot. To prevent any wires from melting, I removed the hall sensors and operate it with a sensor less controller that i bought really cheap, once I took the hall sensor out I replaced the 3 motor wires with 12 gauge (awg) copper cable so it can tolerate the heat. . Will this mod work if the motor is sensor-less ? I would chip in a payment if you were to make a beginners mod video . . for those of us with less experience..
What a such lovely comment buddy. Keeps me motivated to carry on. Regarding sensor-less, it works but the speed motor controller needs the hall sensor in order to detect the position of the rotating magnet. The control system of the speed controller senses the rotor position and the proper voltage pattern is applied to the motor.
Thank you very much.
I have just finished my rewiring from star to delta one of my hub motor for electric mountainboard.
It works. Spinning is much more faster, but motor getting hot faster too, than second hub motor with star.
Also, I don't know how to return to star from delta😅
The ideal would be to add a second hub motor to your ebike to distribute the power more evenly and reduce the heat…
@@Attic-Toy-Design I tied to rewire second hub motor and test speed yesterday. So, I had 4 wheel mountainboard with two hub motors with delta wiring.
1) max speed increased from 27km/h to 45km/h (may be it could go faster, but 45 km/h was a little bit scarry on mountainboard)
2) torque reduced by two or may be tree times.
3) very slow acceleration and braking.
But 45 km/h after 27km/h was amazing!😀
I'm thinking about adding two hub motors on front of my board to have 4wd electric board and increase torque.
Thanks so much for this video - really interesting that you can get 1.8x more RPM with a re-wire.
One question though - That shrink wrapped group of 3 wires during your disassembly was likely the star point (at 5:20 in video) - is there a reason you went through that whole snip/label/rewire and didn't just wire those directly to the delta points?
For what it's worth - I just rewired one without the elaborate labeling, cutting, PCB etc.
********Follow this advice at your own risk. I take no responsibility for you blowing up your motor & or controller.*************
De-solder the star point. (Look at 5:20 in this video)
Identify each strand as A/B/C - these are the ENDS (use a multimeter in continuity mode)
On my motor, the winding order of the 'STARTS' was A/C/B (place where colored wires come through the hub and connect to the enameled wires. Green/Yellow/Blue colored wires). This was top to bottom with the hall effect board on the right side. YOURS MAY BE DIFFERENT.
Wire the END of A to the START of B, the END of B to the START of C, and the END of C to the START of A.
Take special care to cover all connections to prevent shorts.
I was able to test mine without fully sealing it back up to make sure I didn't short anything and that it still worked.
I got about 2.4x RPM (unloaded) after this modification (680rpm->1675rpm). Obviously reduced torque, but I didn't need it for my application.
Thanks so much for this video - it put me on the right track to do what I needed to do. Keep it up!
@@VinceAnido how was the torque affected? i want to do this for a go kart project
@@pavletrnic1433 negatively 😔
Based on the simulations I've seen it's virtually a perfect trade-off. 1.8x RPM for 1/1.8 the torque.
You may want to research wye/Delta switching. It's a technique used in scooters and bikes. Basically you bring out all the leads and make a switch to go from Delta to wye on command. Kinda like a two gear transmission but electronic.
@@VinceAnido so i would have all the coil leads coming out of the stator and then switch them externally?
I looked at the PCB circuit and it's a star( Wye) connection, not a delta? Am I right? The ends of all windings are connected to each other on the back of the PCB.
PCB was designed to be Delta. I know, could be a bit confusing at first sight…but you can do the same job without the PCB, just using wiring…
This is my test, 22vdc and 2220rpm th-cam.com/video/y_FQ3NA-26E/w-d-xo.html
Yes it's not delta. It's stell a wye. This modification change turns of the winding on the coil three time. So kv it's now 48. If you changed to a star it would be then 86kv
@@jara9813 Ah, so what's what it does. I was confused looking at all those wire ends. Conversion to delta does not involve cutting any wires or adding a PCB. There will still be only 6 ends, which are soldered in pairs to the 3 wires that pass through the shaft, as opposed to the original wye termination where 3 of the ends are soldered together and the other 3 go to the shaft wires.
Between 8:06 and 9:06 you switched yellow and green lol :)
But nice work.
Hi dude! Yes, you’re right. I did it purposely…not by mistake..
I have a working hoverboard motor (tested on another system ) , I have purchased a brand new 36v controller with lcd ( s866 ) brand new throttle and brand new hoverboard battery for my e bike project but I'm experiencing no throttle issues I have checked voltage and purchased 3 brand new throttles checked wires tried swapping around but still no throttle
Hey I no you add a link for the pcb I don't no how to go about ordering. Is it possible to send me a link where I can buy the same thing that you have. Love your video by the way
Hello! The PCB factory website and the gerber files links are on the video description.
You don't need pcb from the video. You can use 4 wires to solder in delta. Just see instructions of wiring.
I will use this engine as a wind generator. Can I get more amps and volts if I do what you did?
Wye (Y) Star provides more voltage but not current increase. Delta provides increase in current but not increase in voltage. It will depends on what is your wind generator application project is for. There is one more reason in star (Y) connection. There is a neutral point that neutral wire can be drawn using that neutral wire and any one phase can be used as single phase..
Hello, good morning, I am writing to you from Colombia, I wanted to ask you a question, I am clear about how to identify the coils of b1 -be1, g1-ge1, y1-ye1 but I don't know how you can identify which would be the b2, y2, g2 to follow the sequence
Thank you
The same way you identify the other coils…if you try to watch the video and pause, could help somehow…
@@Attic-Toy-Design same question...it is important to know which end of a coil is "current in" and which is "current out". If it's picked at random, we could get opposing magnetic fields.
I guess the most simple way to keep track is to label as soon as we cut the wires instead of cutting them all and then labelling them.
In the beginning of the video, check the first drawing that could be useful for guidance. When you start the process for the modification you will realise that is pretty easy and intuitive to find out the in/out of the coils. You made a good point in identify the wires when cutting them. Thanks buddy!
Hi:Can you make a video to connect these 9 coils in series to become a low speed generator?
Yes, once I get some free time, I can do it…
Is the torque about the same? And would this overheat over a heavy load?
Hi Jakob. Torque is a bit less on a delta config. And yes, that’s true. Could overheat on long distances and heavy load. My recommendation is if you’re planning to make a 1DW escooter, make it 2WD instead, as you can distribute the load and power more evenly and obviously reducing the risk of overheat.
@@Attic-Toy-Design okay thank you great video by the way!
its not 3 times more speed, more like 1.7 times
hello my frend can you upload the schematic pls
Did you modify the hall sensors too??
No modifications on the hall sensors at all…
@@Attic-Toy-Design Thank You very much. Did it drain more current after modification or same as before at x3 rpm ?
Hello my friend, please answer the question? Use in wind turbines How to make it spin slowly and reap the benefits
Sorry take too long to respond. Here we go! Would be perfect for wind turbine. There are some good projects from good enthusiasts on TH-cam on how to fit good wind propeller..
Does have less torque and more speed after modification? Is there a way to do they oposite? Thank you
I‘ve runner a Kelly controller (KLS7212S) on my Hoverboard Motor. I build a scooter out of it. Now it runs at 3KW and has lots of torque. I never thought that such a small motor can run that power.
Yes. To have more torque, just leave it original, as the original is a Wye/star configuration.
The motor's speed and torque capabilities should be the same. This only changes the proportion of voltage and current. You can get the same effect by using a higher voltage battery on the unmodified motor.
Puedes explicar por qué se unen todas las "y'y todas las " g"
Test in control rc
What voltage you used on the controller when you show the motor running?
Hello buddy. 36V 12Ah lithium battery pack
@@Attic-Toy-Design Okay, quite a nice speed for such a low voltage system.
Ich habe eine frage Ändert sich die Leistung? Also braucht er dann mehr Watt ?
Die Leistung ändert sich definitiv. Weniger Drehmoment, aber mehr Geschwindigkeit. Durch den Wechsel von Stern (Y) zu Delta ist eine leichte Überhitzung zu erwarten. Wenn Sie ein Projekt haben, verwenden Sie am besten 2 Hoverboard-Motoren anstelle eines. So können Sie die Leistung gleichmäßiger verteilen und eine Überhitzung vermeiden.

Hi
Ich Habe ein Problem ich habe mir ein E-Suter gebaut mit allrad aus ein hoverboard das Hinterrad wird mit 1,8Kw betrieben und das Vorderrad Mit 1Kw der akku hat 52v 24Ah.

Bei zirka 30Km/h Hat das Vorderrad Aussetzer der Motor geht aber Wieder an Und dann wieder aus.
Ich würde mich über eine Antwort Freuen .
how many volt doe you runn the motor at????
36V 20Ah lithium battery
hello, good afternoon, I would like to ask a question, I am converting the motor, but analyzing the schematic of the circuit I see that the coils come together at one point. and this is the star configuration, the delta comes with the coils in series
Exactly! You don’t need the PCB for this project. Just use a 10AWG rigid wire for the coils connections.
@@Attic-Toy-Design 10 agw wire is overkill i reamed you to use 18 awg wire to solder the motor coils, but 10 agw will work fine to
how many watts can it stand without modification? and with modification?
its the same 350w
Sorry take too long to respond. I would say more than 1200watts. That’s why I would recommend front and rear motors on your e scooter project in order to distribute the power better and reduce risk of overheat…
Mantaf skema lebih mendetil. Saya kira itu di likit ulang dgn kawat ukuran 6mmx8 lapis. 1 pole 5 lilitan dan seterusnya mungkin watt akan bertambah tidak 350 watt mungkin jadi 1500 watt. Tentu putaran lebih cepat.
Yes! You are right. That’s why I recommend make your e-scooter project with front and rear bound motors to distribute better the power reducing the heat…
Why do all the end points come together? Is that not star config?
Star (Y) is the original setup where all end points comes together. Changes were performed for Delta setup.
All endpoint still come together on your pcb. Are you changing from series to parallel?
@@fleetcommand3499 I know it could be a bit confusing. But the configuration after modification is Delta Triangle, kind of series. In the beginning of the video there are some drawings showing the difference..
Boa tarde,o ruim é que a resolução do vídeo ficou com o tamanho muito pequena e dificulta te uma clareza no vídeo.
Verdade José Roberto…estou adquirindo mais experiência em editar os vídeos. Os próximos serão melhores. Sorry…
Wooww .. wiring star / delta ? Or star&delta
Just delta configuration. Star was the original setup.

I read through the comments and found a listing on eBay but there is only one left ( Currently in cart) thx to whom ever that was again I'll like you in a moment
@Eduardo Santacruz
with 500w you dont have heat problems running on a long time?
Yes. Definitely. But if you develop a E-scooter project using front and rear hoverboard motors to drive it (2WD) you can distribute better the power/torque as a result of less heat if running long time…

I’m looking at buying your pcb you sell any more new videos
Hi Elliot! I’m planning to make more videos this summer finishing the E-scooter frame and batteries. The boards I have on eBay are quite useful but you need to reinforce the cooper tracks with plenty of lead free solder wire to support the high current generated by the motors and batteries.
Hi I loved the project, how can I order such an electronic circuit?
Hi! You can order a customized round PCB on the description. There is no much electronics circuitry on this modification. Only the hall sensors you must to rewire back to its original. Take some nice photos before you start your modification for a good reference about your hall sensors.
@@Attic-Toy-Design Can I give up the board, and instead of the board, wire wires like in the motor coil. If so, what diameter of wire should be used?
Of course you can! The round PCB is to make more neat and professional but you can use any wiring that can handle high current at least 10A
@@Attic-Toy-Design Excellent, thank you very much.
i just did that but the motor gets hot really quik and even with no load on it. the torque is considerably lower at lower rpm
Probably you did something wrong with the coils…maybe you mixed up the coils. Only get hot if you put heavy load for long time…I would recommend you double check the coils connections and wirings…

Well, I didn’t test the modified motor with a hoverboard main board controller…I used a e-bike 36V 800watt speed controller. Maybe the hoverboard main board is doing something dodgy with the modified coils..I really would like to help you…but I am unable right now, as I don’t have a hoverboard to test it…I will try it once I get one…please, keep me informed if you find out something or a solution for your project.
@@Attic-Toy-Design Thats ok thank you, i will test it again on the bike, when i finish the battery pack, as i dont have a bigger controller for now. Even if it is not suitable for my bike gears setup(require more torque rather than ), i will use it for other projects, or use it on the bike with a bigger gear in the back wuch require less torque and more rpm. Either way great project Thanks
Another option that i think of is that my current battery is weak and so is the controller as you said, and being unable to supply more voltage to the delta config, it will draw more current, like all electronics do when they need more power and there is not enough voltage. il keep you updated

i don't get it if this thing can go 3x speed with almost same amount of torque why manufecterers or everybody doesn't use this the must be a something negative about it maybe so much current draw or unhealty for the motor driver pls enlighten me
Less torque, higher speed, high current, increase in temperature, less battery range. This is a hub motor modification for a e-scooter project using 2WD (dual motor) instead of 1WD to compensate the less torque and balance the high current drain ad the temperature. High performance e-scooters use this system to achieve high speeds (80-100km/h). I hope I have enlightened you.
You will overheat the motor if you run it for long period of time. What's the point? You need also design liquid cooling system to use it. LOL
I have tested the motor with load and I notice some heating but noting so significant to the point of the motor get damage or even add an insane liquid cooling system and you mention it. Lol
@@Attic-Toy-Design With the same voltage the same 3 faze "Triangle" winding connection will consume more Amps than "Star" connection. Just put it under the load continuously for 30 minutes and see what happen. LOL
@@tigranohanyan3321 More Amps but lower resistance, so heating remains the same for a given torque load.
@@dekutree64This is ridiculous. For higher voltage you need to increase the length of the copper wire and decrease the cross section to fill the same gap in stator. ( to keep the same heat dissipation) The resistivity of copper wire (ohm x meter) is the same.
@@tigranohanyan3321 That is correct. The modification in this video is the inverse, reducing the length of the wire by cutting the coils and putting them in parallel groups (more cross section, less heat for given current).
