DFGT with a xbox 360 fan...cool

Your DFGT sir, is awesome!

 

[Raitziger]

Nice clean job!

 

[lunarwolf]

very nice craftsmanship. did you do that because it gets hot and fails?

 

[Rylan]

That's very, very nice.

My only recommendation for you after having spent a fair bit of time in the PC modding business...buy a fan grill. That thing is just begging to suck something in and if it does, and you're playing at the time, you'll knacker the wheel.

But really...very nice!

Still using this bad boy!!! But I've made a few changes

My stand is a $30 Walmart book shelf

After I get a new wheel (here soon) ill be replacing the stock motor with a a traxxas emaxx 21 turn 550 brushed motor to see what it'll do.

What it will do is not work. Those R/C motors draw way more amps than your stock motor. The net effect of this is your power supply's voltage will drop when the motor tries to draw more amperage than the supply is rated for and it will shut off, either until the amperage draw drops or you turn the switch back on, depending on how the electronics in that wheel work. You could try adding a beefier power supply that can handle the amperage draw of the replacement motor, but then you might fry the electronic circuit that runs the wheel, since it almost certainly isn't rated for that kind of amperage.

I see

Ok, appearances can be very deceiving. The motor in your wheel has many turns of very fine wire. Likely over 100 turns. The stock Fanatec motors for instance, have 130 turns of .22mm, or about 31AWG (around .009" diameter) wire. These motors stall at about 2-2.5 amps (stall is the point where current draw is highest, and where most sim wheel motors spend a high percentage of their time). A motor from even the weakest R/C car or truck of the same can size will likely draw 15-20 amps of current at stall at rated voltage, (probably around 8.4-9.6V for a 7-8 cell pack) and is designed to run probably at least 20,000 RPM at that voltage. The motor in your wheel is designed to pull probably 1-2 amps and probably run around 4,000 RPM at 24V.

There are many many varieties of 550 motor, all with different windings. A motor with a winding suitable for use in an R/C vehicle would draw way too much amperage for a stock sim wheel.

Can you imagine though?


Sit down to play GT5, hit the wall and the wheel launches you out of your chair.

I just did a quick search for emaxx specs and take a look at this page:

http://traxxas.com/products/models/electric/3903emaxx-specs

Apparently the E-Maxx is designed to work on 16.8V, but take a look at that motor controller's amperage rating! 30A continuous and 180A for forward/reverse, 360A braking! I believe it uses 2 motors, so divide by 2 to get what you might be looking at running one of those motors, then since your wheel runs at 24V, you need to multiply the amperages by 24/16.8 to get your numbers. So with 1 motor at 24V, your DFGT's circuit would need to be capable of a max continuous load capability of 21.4A, peaks up to 128.5A! There's no way it would have that much over what it would need to run its stock motor built in. If you want to try it go ahead, but it would be a waste of money unless you plan on basically redesigning the entire circuit board.

 

[eKretz]

Let me ask you this. On your power supply that plugs into the wall (the wall wart) what is the current rating? That is the maximum amount of power the supply can give without dropping voltage. If you exceed that amperage draw with your motor, your wheel will just shut off.

 

[Novamega]

Your speaking to me like im a novice and I

 

[Novamega]

I've also run the 12turn and the 21turn Emaxx motors at 7.2v all the way up to 24v and ran fine. Even at 7.4v it was running fine without any cogging and turning good rpm.. I use a watt/amp meter to test with

 

[eKretz]

Your speaking to me like im a novice and I don't know what I'm talking about btw the way it's 21v..... I would have never thought about doing this mod without researching.i understand electronics been racing rc for 20 years and modding/working on PCs since the 90s ...

Yes I've tested these motors with many power supplies and used them in a few different apps
Here's stock specs

I'm not treating you like anything. I made the statement that the motor won't work without a lot of modification to your wheel and a new power supply. You challenged my assertion. No offense intended, but if you think you can use this motor in your wheel you don't understand how this stuff works very well, and we wouldn't be having this discussion if you were as well versed as you think you are. Look right there on your datasheet at the stall current. Your wheel will just shut down if you try to use that motor. Even if you got a new power supply with enough power to run the motor, you'd fry your wheel's circuit board.

The voltage is not the problem, it's the amperage. Any motor will run with a multitude of voltages, they just have a shorter life at higher voltages than they're rated for.

 

[Novamega]

That data sheet is for the motor I'm using now

 

[eKretz]

No it isn't. It may be a 550, but it most certainly isn't the motor from a DFGT. I can guarantee you that much.

 

[Novamega]

Ok

 

[eKretz]

Your picture clearly shows a stock motor. Are you saying you changed it now? Because the data sheet you posted does not belong to the stock DFGT motor in your picture. There's no way the motor from that datasheet will work. Look at the amperage draw for yourself, numbers don't lie.

 

[eKretz]

Ok whatever lol ..How you gonna tell me? I've had one inside the dfgt for almost a year now and one right here in front of me but ok.. WOW dude .. Go troll someone else's post

Right. I'm the troll. So you've been running this non-stock Mabuchi 550 in your wheel for a year, eh? Explain this from your earlier post, (yesterday, not a year ago):

My stand is a $30 Walmart book shelf that turned into something waaaay better in a few mins. got a new pc fan grill,and a push on\off switch for the fan. After I get a new wheel (here soon) ill be replacing the stock motor with a a traxxas emaxx 21 turn 550 brushed motor to see what it'll do.

I think it's clear who the troll is.

 

[Novamega]

Like I said .. Find a hobby troll I'm deleting this

 

[eKretz]

Riiight. I guess that's why yesterday you were writing about replacing the stock motor. You're just digging yourself deeper. I still don't get how calling your BS would make someone a troll.

 

[eKretz]

Like I said .. Find a hobby troll I'm deleting this posting ... Trolls like you are the reason I quit coming to this site.... the reason I did the fan mod in the first place was because it burned up back in 2010 , but you seem to know everything

piss off

Nope, don't know everything by a long shot, but I do know how electric motors, Ohm's law, and a fair bit about how electronics work. Way to keep things civil, BTW.

 

[Terronium-12]

All I see here is someone trying to help you and you calling them a troll for no reason, and since you're starting to edit your original posts for whatever reason... let's get one step further and prevent you from furthering this topic.

Locked.
