Showroom Thrustmaster T500RS Motor Upgrade 65W to 85W - SUCCESS 01/23/16

EDIT 01/23/16
All assembled - and it works so far. First tests are very promising, 30% more gain, better feedback, harder pikes. A detailed doc and a video will to be uploaded on Monday 01/25/16.


Hi folks.

My new project: I will add a stronger - 85W - motor to the T500RS by replacing the standard 65W motor. The DC motor is a Bühler 24V DC motor 1.13.044.289 (or 1.13.044.236). Bühler offers a slightly stronger motor, same diameter, same rear shaft which is used for the encoder which monitors the position of the motor and in turn the wheel, same rpm but more Nm and slightly more watt but longer: 103.4 cm instead of 88.6cm. The upgrade is moderate so IMO ( ) the T500RS should handle the stronger motor (if not, OSW is calling...). There is enough space behind the motor so the case should not to be cut or modified. Anyway I need a bigger fan, other parts must be cooled better as before, so probably I drop the case.

The spec sheet:

The motor (screenshot found somewhere from the internet, I did not open the case yet)

Stay tuned (as always

You going to change your power supply to support that bigger motor?

no, not planned.

So I know the motors are both 24v but Im not sure of the rating on that power supply or the h-Bridge on the wheel itself. Are you aware?

yes

btw @shannonb1 you have seen my motto, I like to burn gadgets.

i say no and the reason is why to do all this stuff(spending time money and may not work ,harming a working wheel) and at the end building a DIY wheel. i have a t500 too and i am happy with it don't think that needs any upgrade except a new DIY DD wheel in the far future.

Its a good thing that this isnt your project then. Sheeww!...I have a DD wheel, a g27, a T500rs, a g25 and dfgt...I think it woudl be a cool project to mess with the t500rs.

Experimenting is for me the motivation to do things, even they are not logical or being senseless. No doubt the T500RS is a good wheel (probably the best of the non DD wheels) but it can can be better. For that reason I make this test. Even if it will blow away - I am satisfied

I hope your experiment goes as planned. Progress/knowledge comes always by risking(assuming the cost/risk is reasonable).

If it succeeds lots of people will follow your steps. I hope the oem electronics are capable for 30% more juice(though i doubt it).



ps
I dont want to be misunderstood... but...having experimented with a thrustaster wheel in the past i can only wish you good luck.

Their products are very hard to mod circuit wise(if you happen to see that the electronics cant feed the bigger motor that is).

as far as i remember @Pit wanted to change his wheel(T500) for a DD wheel and had it for sale long time ago and i was thinking and talking like a guy that owns one wheel.

@pipis2015 probably you are right, eventually not. 30% is many, I know. Let me say we use only 60% of the forces (trustmaster control panel) and 70% in AC. If we would set all to 100% the wheel would be on the other hand very very strong but undrivable due to the clipping. My intention is based on my hope that the sensitivity will profit and already beginning from the small forces up to the linearity which has been already not really linear since the T500RS is on the market. Let's see what happens

I have to come back to your question because I changed my opinion, if the PSU of the T500RS can be uncoupled I will use an separate PSU.

Wow that is a big motor in there already. Good luck with the experiment!

Update: the Bühler motor is ordered. Delivery time up to 6 weeks
The standard T500RS Power supply has a 24V voltage and 6.67 A current rating. Eventually this psu is too weak to handle the little more current - if so, either I stick a server PSU using a 4 pin male adapter to the 500RS or if someone would like to use a clear solution there is a 221W 24V 9.2A AC-DC Table Top Power Supply available. But do not buy before I tested...lol

Out of curiosity, when you open up your wheel are you able to read the part number of the FETs or H-Bridge driver on the board?
Might be able to determine if the bridge can handle the power upgrade.

When I am ready to start I will have a look at this. Thank you for the input.

I found a picture of a burned T500RS due to a short out of a bent pin, eventually you can detect something already...

An other one but not sharp enough:

Food for the electricians There are four P120NF10 on the board.
BTW to disassemble the motor of the T500RS obviously I have to disassemble the complete wheel... :-/
