Has anyone attempted to swap out the motor for one that spins faster (and increasing the centering speed) or even possibly modifying it to use a belt drive? A belt drive system seems easy enough if you keep the stock gears and use a serpentine belt of some sort and modifying the large gear with a guide plate. The main mounting plate for the motor would need to be re drilled and motor wires switched around. It seems that a belt drive would make it have less resistance compared to gears but I could be wrong.

A new motor would be a lot easier but finding out the exact specs and rpm it turns would be difficult to find a proper replacement
 
I made a thread about this but didnt get anywhere.
Imo you'll probably be able to fit a 540 size rc motor in it.
 
I tore into my wheel and it looks like you can modify the internals to make it a belt drive with some cutting and an extended shaft and pulley setup. Motor wise I wonder if I can shoot an email to Logitech for the specs

I also noticed the motor itself has a lot of turning resistance

I think this is possible but a brushless setup would give the best results more free rolling so less resistance , could be super fast aswell.

True. But could you keep a proper rc gear on it?

And could you post some pics of the inside?

Ill try getting some pics up later. Its very simple inside. I don't know how RC fears fit on the shaft but the dfgt has a simple D cut shaft for its gear. I finally did one mod I've wanted to do since I got it, and that's a button near the shifter linked to the O button for an e brake. Was really easy to do. Haven't tested it but it should work.

Oh, about using an RC motor, it should be very easy to find a proper gear with the same tooth count asthe dfgt from the looks of it the big issue is voltage and current draw.
 
The gear fits on the rc motor by a piece coming out of the motor and has a flat side. Then the gear slips on and has a tiny screw in it amd you put the screw on the flat side.
Rc motors usually have a 7.4v current or whatever you call it, so you may have to do something about it.
 
Just looked at the inside. The motor is big enough, a good bit bigger than a 540 size rc motor.
For the rc specialists, is there any bigger motors than 540 size motors?
It shouldnt be hard to do, but it might be hard to find a motor with all the specs.
Edit: looks something between a 600-650 size motor.
If we put a brushless motor in it what will we do with the earth wire?

It is a big motor but it seems to have a low rpm and Im wondering if its a standard DC motor cause the wheel will stop rotating without a ton of effort if you set it to say 270* rotation.
When I find my multi meter ill try getting some data on what voltage and stuff like that


Edit:I hooked up my multimeter, this motor is a pig. Maxes at 24v but I don't know how to get proper amperage readings. If I had to guess it must have a max draw around 700 maximum since the powersupply only can handle 750mA
Funding a motor like that would be tough. Might need to drop the voltage to 12v

These guys have done a belt drive conversion using a G25 may be of some use to you.

I plan to think on a way to convert my G25 to belt drive, But if it turns out costly I plan on just building a HAPP wheel using my g25 as a donner.

Yeah, but its 576 degrees. And i would hate that.

Edit: it said one of the motors carry a steering angle sensor. Is that the same with the dfgt? If it is we cant replace it.
 
yea that one is 576 but they say it increases torque.
But I suppose you could still do the same thing with the dfgt, But from what I could imagine your going to need to do quite a bit of fabrication.

I guess it all depends on how you do it.
You could try and incorporate a belt drive into the original DFGT casings. or you could build a hole now wheel enclosure and mechanical parts and the use the dfgt electronics and motor in the new enclosure.
There will be advantages and disadvantages with both methods.

If you scroll down the thread you will see a pic of a HAPP arcade racing wheel.
The HAPP wheel uses a belt and one big motor.
It all look quite simple too the motor is placed to one side of the box with a belt going from the motor to the steering shaft.

As for the sensor I do not know but it should not really matter if you did belt drive it as you could just fit the potentiometer or optical sensor to the end of the steering shaft then the game would have a reading of wheel alignment.

I plan to build a new wheel soon, I am busy making plans and testing parts.
I am undecided on weather I am going to buy a HAPP wheel and use my G25 to give the wheel a game signal, or build my own wheel from scratch and use my G25 internals.

Either way I really dont think the belt conversion could be done with little fabrication.

EDIT - I also think that you will lose a lot of feed back using the single dfgt motor on a belt drive as I dont think it will as direct as gear driven wheels.

The dfgt has a normal motor. Sensor is on its own. I think i could modify the gears themselves to run small but heavy duty belts right on them. As long as the belts are tough enough with the right tension it should work good
 
I haven't gotten a chance to try and contact Logitech about the motor it uses, nor have I dug into what it would take to put in belt pulleys. I know it ccan be done though.
One bit of info iI could use is what gear ratio it runs
