DIY FFB Steering wheel (MMosFFB ) (In Progress)

Cool))) Use 0.9. so guidances were uppon it) That's great )

Awesome project!
I'm wondering if the software works also with sensored bldc motor driver.
Does it?

Do not think so

Actually @Alexey put some image on wiring a BLDC controller in the first pages of this thread, but I don't know how it ended up...

I wanted to build my own ffb wheel base with a 400w BLDC motor. With some gearing, I calculated a nominal torque of 7.5Nm at 1000 rpm at the wheel. The peak torque should be definitely higher. Basically I was looking to build something more or less powerful as a Fanatec Clubsport v2.5, but definitely cheaper. Currently with some cost estimation, I can get controller, driver, motor and PSU for 160-180€, which compared with a 549€ wheel base it definitely cheaper...

The only thing I need is the FFB software. I can make it on my own, but it will require me too much time to figure out FFB over USB interface and stuff like that. Thank you for your help!

I just found out that the software for arduino was proposed by @auryza . I found in some video that it has more signal options for the controller (PWM+DIR, PWM+/-, ...) I was just wondering if it was supporting signals for BLDC. Does it?

Hi! I build my own DIY wheel and pedals.
Some information which found here in some comments was very useful. Thank you guys!

Some picture about the assembled wheel and pedals.

Sorry for the three post but I couldn't send a link before my third comment.

tomthomas21, very nice!
What's the device on the shaft?

Thank you!
I didn't want to use a cable to the buttons on the steering wheel. So I built a sliping rings for the connection between the arduino and the buttons. I used a hollow shaft, the cables there are in it.

Very cool solution!

Nice build @tomthomas21 !
What motor are you using? It seems quite fast!

Thank you!
I used a Denso 45200 05271 power steering servo motor from a Toyota with 4:1 ratio. I measured 14 Nm on the steering wheel with 67% performance (power supply: 12V 480W).

I forgot to ask, which is the output power of the motor? And what you mean for 67% performance?

tomthomas21, could you give the name of the pulleys with a belt please.

I dont know the motor output power, so I wrote the torque. The main gain can be controlle from the software, so with 67% setting I measured 14 Nm torque on the steering wheel.

I used HTD-5M timing belt with 60 and 15 teeth pulleys.

Hi guys , Just finished 1st stage build of my Reduction drive FFB wheel and Wow @tomthomas21 just seen you rig , that is some nice engineering and loved the slip rings idea , thanks for posting .. just wanted to add thanks fo @Sieben for the info that go me on this journey , attached ia my 1st attempt at proper Build , but already im thinking I need 4:1 instead of my 3.25 :1 .

notice you guys seem ok with putting electronics inside the wheel housing , I thought vibration might have been an issue so I had mine in separate housing .. Trying to put togather and assembly slide show an will post it on youtube once done .. also will start my own build thread , but as mentioned ....big thanks guys for the inspiration and all the help .

wannabeaflyer2 Wow, that's a very nice tiny housing! Thank you pal for kind words!

Cheers @Sieben once its all finished i'll put cad drawing on My new Post , took load of photos but don't want to overload the forum LOL so U tube slide show may save the day LOL ..
one last techie question ... when I do wheel check and select spring test , it feels great in one direction but notchy and judders in the opposite direction . can any one say what likely to be happening here Cheers
