Buying a new wheel

98% of servo motor's are made in China based Factories, like most other goods you and I use everyday.....quality is of no concern here. You essentially dealt directly with the mige motor factory. The cable and quick connects are Super nice quality with double joints to move them where ever you want. Overall its a Super nice piece of kit. 25lbs(actual weight) in a 5lb bag is how I would describe it. lol

Fanatec is engineered in Germany but of course manufactured in China.

 

@Nick Moxley, @XettMan , oh well then... it is going to be from China. It is not that bad if it is only assembled in China.

 

Anybody have a chart with Nm torques for most common racing wheels? I know a Nm is 1 Kg of force applied to 1 metre long arm but the arm of most racing wheels is about 15-20cm. Does that mean a Nm would be 5kg applied to 20cm arm ?

EDIT: Sorry, 5NM - 1kg on 20 cm arm, got the values the other way around

 

Think it's the motor inside that's rated?

 

Yeah, I'm just trying to visualise it in my brain, how much force my arms would need to apply to turn the wheel on 20 cm arm, not 1 metre.

 

I think you would take radius of 0.2m diameter wheel. So pivoting arm would be 0.1m. And then you have to use not Kg which is mass, but Newtons which is weight force, F=mg, and for 1N you would take about 0.1Kg, because g~9.8m/s(square).

Then 5Nm would be 500g pulling 1meter length leaver, and if it is 0.1meter length leaver, then it is 5Kg.

If I'm right, though it is simple, always confuses me.

EDIT: well... I guess you meant radius of the wheel as "arm", 20cm diametr wheel would be crazy small....

 

So if you attach a 10kg weight on one side of the wheel, a 12 Nm motor would lift it, assuming the arm is about 10cm. That's a strong FFB rotors you're talking about there. I wouldn't even think about driving with such a strong ffb.

 

Well, lets take it is 599xx alcantara wheel, 30cm diameter, 15cm is radius. The motor has 12Nm peak torque.

It would lift 1.2kg mass on each side, of 2meters diameter steering wheel If my super complex calculation is right, then it would lift 8kg with 30cm diameter wheel.

Somebody fix me if I'm wrong here. I've been in math related hybernation for some time.

But I don't understand how this torque figure works with rpm. Because it could lift fast and slow, I guess it wouldn't be lifting so violently on top torque ?

 

I'm happy with my DFGT strength, so a 2.5 will be more than enough for me. Linearity is another thing tho..

 

I think it really depends where you come from... Had a DFPro before my T300 and jesus the T300 is a monster @ 100% strength. I really can't imagine how to use the direct drive wheels? Maybe I would end with two broken arms when hitting a wall, because of the wheels I'm familiar with.

 

You have 100% in your driver?

 

No 75%, just tried it a few minutes once...

 

Going to jump on this thread as well, what would be a good upgrade from a Fanatec CSR ?

 

I don't know what one of you jokers thought it would be funny to come and break my wheel after I was on here praising it's robustness, but you're not funny!

Lol in all seriousness, my t300 has started making a loud clicking sound while spinning quickly... Mostly can be heard when it's spinning during its initial calibration when you plug it in.

I emailed TM last night and they replied pretty much instantly asking for a video and some images of label on wheel.

I sent them that and again pretty much instantly they replied that it would need to be sent back for repair / replace. They asked for address etc. for label and I replied with that late last night.... Just waiting to hear back from them again but although not entirely happy about wheel clicking, it still works perfectly well for now and they have handled it the best they could so far.

 

Oh well TM's support is sure busy and developed. Maybe it is murphys law worked up on you. Things we are afraid, or very worried about, or focused at, has increased chances to occur. Like if you are playing football and get alone face to face against the goal, and if you think "what if I miss" you may miss. I don't know how bad the clicking was, but IMO some of those sounds can be temporary.

 

Yeah shoulda kept my big mouth shut... Here is the video I sent them, you can hear in it that it's certainly not temporary and it's also been getting worse since it started so can't see it going away now.

 

Dude, I joined a server other night and my wheel took a flakey,strong ffb/spring feeling, wouldn't calibrate properly for wee while, but it's sorted itself out now, others have told me it's an AC bug?

 

Never heard of that in AC but same thing happens to me in pCARS every now and again, even in practice etc myself and I need to restart the game.

 

@davegreengo Yeah that doesn't sound healthy. Sounds like something got loose. You probably did right to report your issue soon.
