DD-Wheel with Hoverboard Motor

Is it this one? https://github.com/benjaf/hoverboard-firmware-hack-esk8
No instructions there. I think I found the original - it is complicated. Those drivers I mentioned also accept PWM, but it looks like it's just a single PWM input for both directions. SMC3 seem to need ENA and ENB in both modes. Not sure what those are, but I think they set direction? So I have no idea if SMC3 PWM can be output in compatible mode to set direction etc. when there is no ENA/ENB wiring that I can see on those drivers, and I think not on the hacked hoverboard boards either.

So I've been researching these hoverboard DD wheels for a couple of days now, and it really seems like a great option for the price.

So far I have picked out:

• 6.5'' 250W 36V hoverboard motor
  
• ODrive-3.5 single motor driver
• 12V 20A power supply
• AS5048 magnetic encoder

Because of packaging I thought that using a magnetic encoder would be far easier than making brackets and trying to somehow attach a rotary one. I've seen multiple people go this route and I was wondering if there was a go to solution for mounting, maybe someone could provide me with some info on what would need to get drilled, about using radial magnets or a magnet ring?

Hi everyone.

First I hope I can keep a conversaation with my poor english.

Now I tell you that I´ve started with this project last week. I´m "handyman" but electronic s not my business.

ok.

Here´s my BOM:

1) BLDC hoverboard motor
2)JYQD v7.32e ESC (know that´s not ideal but is what i have to start)
3) Arduino Leonardo whith EMC software/firmware
4) 600ppr rotary encoder.

Yesterday I was able to make the motor work with the esc using a potenciometer. The same start with arduino and encoder communicating with PC (proved in Automobilista 2 & iRacing)

Now (and here s my first "with a little help from my friends") I don´t know how to connect arduino pwm to ESC. I dont´t know wich pins of arduino use for that.

Ok friends.................too much for the first time

THANK YOU!!!!!!!!!!!!!!!!!

Hi,
I have been following this thread with a lot of interest. I am planning to build a did fb wheel using 300w hoverboard bldc motor and B-G431B-ESC1 driver board. Before ordering the parts, I have a couple of questions.

Is the firmware by @Benu for the esc1 open source ?
Are there any alternative firmware for esc1 if we can't get @Benu's firmware ?


Thanks

Hello. I've recently been somewhat obsessed with making my own DD wheel & stumbling upon this thread as well as the "Cousin of OSW" has been a blessing. From all the research I've done on here, it seems like you guys prefer to use a MY1016 or a hoverboard motor, but what do you think of electric scooter motors? I've seen them being quite cheap & their wattages range from 250 up to 500W with 36V, however I wasn't able to find anything regarding the amperage as it seems to be a secret for some reason The main upside of using such a motor is that it's even more compact than a hoverboard one & possibly even cheaper for the same specs, depending on where you will get it.

I won't start my project anytime soon, but just wanted to know what do you guys think of it? The most popular electric scooter motor I've seen is for the Xiaomi M365 (Pro)

Welcome!
The Xiaomi motor looks just as good or better than a hoverboard motor. It's the torque you want, and smaller radius motors have to work harder to produce the same torque since it doesn't get the same levarage. At the same time, bigger motors are heavier so they won't be as responsive as a smaller motor. Soooo, it is all about the perfect compromise.

You can estimate the amps using P = U * I <=> Wattage = Voltage * Current => Current = Wattage/Voltage. I'd say never mind though, it'll most likely be enough.

The motor is the easy part. Finding a driver and making an encoder solution for it is more difficult.

The esc is compact and very capable, but unfortunately takes a looooooot of knowledge. Especially since Benu seems to have taken an extensive break from xsim.
The Vesc is more user friendly, but I haven't gotten around to testing it myself yet.

Hello dear friends!

I'm in the progess of brainstorming the method of reviving a broken Thrustmaster TS-PC. The motherboard is toast, so that's out of the conversation. The wheel uses a brushless motor with belt reduction for increased torque. The motor is a B5665m with integrated hall sensor. The unit has hard stops for limiting the rotation.

I'm basically asking if i can go the route of VESC+STM32 disco board for my setup.

Thank you,
Paul.

Hi all, I've been really enjoying the journey with you guys, reading all the posts!

Has anyone come across the Near Zero controller. https://skysedge.com/robotics/nz2/index.html

I would like to get a controller and Robowheel from this site and build a ffb steering wheel. Any input would be welcome.

Regards from the UAE.

Looks like a nice base! Start a build thread when you get it!
VNM supports CAN I think, so would be a good match.

Im observing this thread for a long time and see no progress. Is this project dead?
I saw that one-piece hooverboard pcb was used as cheapest way to get working wheel. Why it cant be done with even cheaper and easier to get two-piece hooverboard controller?

@Benu, TS and code writer has taken an extensive break it seems. The firmware needs to be custom, since encoder counts and such differ from unit to unit.
There are firmwares for the original boards, but I'm not sure there is one that supports encoders and FOC at the same time.

So, yeah. It has become a little too difficult to build this for the thread to stay alive I think.

Of all that is in this thread, you have the coolest project !!! and a very serious engineering approach! You're cool!!! how does your driver work? how to manage it? and what is the cost?

Better DIY in this thread, but a little information about your controller .

It works awesome. A bunch of guys copied my project and build their versions based on it.





And i build FFB joystick based on two axis wersion of it:


BUT. Because of global chip shortage it become very difficult to find components for it with resonable price
That's why I developed custom firmware for ODrive and plan all my next build on it. It is compatible with ODESC3.6 as well. Schematic of connection as simple as


And all development plans are for ODrives/ODESC3.6. Because it is easily sourced on aliexpress.

Hello, have you solved this problem?
How can I do it, @ danove_ B's code needs to be incorporated into @ Benu's firmware?
https://www.xsimulator.net/communit...th-hoverboard-motor.13178/page-24#post-209025

No, I just put a switch close to the wheel..

Yeah, you’d need Benus source code, add Danoves magic and compile.

It seems that we can only use it like this first

How it going to ODESC3.6 way

Hi, I have 250w hoberboard motor, (weird but plastic back cap).and odrive3.6 56v. When I try to calibrate motor I get curren measurement error. Why it should be, how can fix this issue? Could anyone help me?
