DIY FFB STEERING WHEEL

Hello everyone


I'm starting a project of a steering wheel with force feedback, help me with the components I'm studying, what do you guys think? I want an 8 ~ 12nm ffb

Dc motor
Encoder
BTS7960
Driver (Why do some use 2?)
Arduino Leonardo R3 Pulleys 1:?
belt
F1 steering wheel, with at least 18 buttons, will I need another correct controller card? which do you indicate in this case? thank you all

edit 15/12/2019
some progress in choosing parts

dc motor = 24v 100w 3000rpm
Encoder = 600pr

Im forgot this

Hi,
nowadays many proven DIY wheels exist
what are your expectations? have fun tinckering or expect semi-pro feeling?
what is your budget?
what are you competence in coding Leonardo? (FYI this is a really high level stuff)

Yours
PS : have a look here
https://www.xsimulator.net/community/threads/rfr-steering-wheel-direct-drive-by-racingmat.6309/

my budget $350 ~400

I am brazilian.. I will search servo motor for selling, maybe a direct drive will be more interesting

What you think... This project direct drive how.much +/- costs to do?

This motor works fine in direct drive?

10nm

I have no knowledge on stepper ffb wheel... only direct drives, sorry.

There's two main routes that you can go down, depending on the motor.
Either a brushed motor or brushless. At the moment, using a brushless motor will be the more expensive route but ffb will probably feel better.
I made my wheel with a brushed motor.

I used the components below:-

DC motor : MY1020 24v 500w

Motor driver: 1x Cytron 30a driver (instead of 2x bts)
Micro controller : Arduino Leonardo

Pulleys: HTD 5m pulley and belt. (4:1 rato, roughly)

With that setup, I run the wheel at 30% and that's more than enough.
2x bts drivers are used, as the 1x can't handle much current. But I find that they fail very easily, so use a Cytron driver, which seems to be a lot better.

@Chris Malcolm : interesting! can you share some pictures?
or do you have a dedicated post about your wheel?

[QUOTE = "Chris Malcolm, post: 188514, membro: 32924"] Há duas rotas principais que você pode percorrer, dependendo do motor.
Um motor escovado ou sem escova. No momento, o uso de um motor sem escova será a rota mais cara, mas o ffb provavelmente se sentirá melhor.
Fiz minha roda com um motor escovado.

Eu usei os componentes abaixo: -

Motor DC: MY1020 24v 500w

Motorista: 1x motorista Cytron 30a (em vez de 2x bts)
Microcontrolador: Arduino Leonardo

Polias: Polia e correia HTD de 5m. (4: 1 rato, aproximadamente)

Com essa configuração, eu corro o volante em 30% e isso é mais do que suficiente.
Drivers de 2x bts são usados, pois o 1x não suporta muita corrente. Mas acho que eles falham com muita facilidade, portanto, use um driver Cytron, que parece muito melhor. [/ QUOTE]

thankyou for information

Please show us prints,photos of your project... How these drive works and his wirings thx

@Gilvan Marchiori Araujo : have you had a look on hoverboard FFB wheel?

Yeah Gilvan, I can make a post, showing step by step how I did my build. Probably after Christmas though.

If you have the patience, maybe wait until the hoverboard build has been finalized by the guys in the direct drive forum. It uses a brushless motor, which should provide a smoother feel and better ffb. I presume it won't be much more expensive.
I think you will just have to wait a few months before they developed things, so that the average person can build it.

sorry, i dont understood, what is "hoverboard"

o pretty nice !!


I will take engineering holidays, this week start planning my project ... I can wait yes, for now I will provide the mechanical part, please do not let the topic die, we will always talk! thank you guys

how much nm of torque ? These motors get

I have a idea... Look

Stepmotor nema 23 1.5nm

Pulley and belt 1;4 ratio

Arduino leonardo
Bts7960
Encoder 600pr ( i dont need this right? Stepmotor will be give me posicion)

Its a good idea?

I don't think there are any step by step methods on making a wheel with a stepper motor. They have been made by some people but there aren't any complete guides on how to do it.


I think the first thing you need to decide is how much you want to spend on the electronics. This will depend on if you want a brushed motor or brushless motor.
The brushed motor build will be cheaper, mainly because they are simpler to control. But it might not feel so good, as it will be "notchy". I can't feel it too much, so it doesn't matter to me. The cost of the electronics, including the motor, would be about £160. If you used the same as me.

The brushless motor build will be more expensive but will should feel a lot better. It will also be direct drive. You would generally need to buy most of the electronics from Granite Devices. This might cost you around £600 for the electronics, including the motor.

As far as I can see, there aren't any other cheaper brushless motor builds that have been completed yet.

so chris, in brazil the euro is very expensive, 600 euros is completely out of my budget, i want to spend max 200 euros, i spent these days studying the project and i'm almost deciding the following:
dc motor 12v RS 775
Encoder 600 PR
2 kit pulley and sewing machine belt (4 pulleys / 2 belt) for more torque (6nm +)
arduino leonardo
drive bts7960
psu 12v pc

By the way, if I have 2 sets of 1: 4 pulleys and another 1: 4 will I have 1: 8 or 1:16 of torque?

Curious to hear how you feel about your finished project!

“1:4:1:4” will give you 1*4*1*4=16.

What rpm will that give you?

1:16 will provide me 930 rpm... its good o right?

the rs775 motor have 15.000 rpm and 0.7nm torque
