Floriske.nl's 2DOF Playseat GT Wiper motor Project

ok cool never tried a sim with front positioned motors bsft and deriy have done so successfully thou. I have a joyrider thats constructed as only joystick, my new jrks have just arrived so its time to electrphy the joyrider and i will have a decicated flight sim. But again nice progress and the jrks will work well like that be interesting to compare.


Is this what you were looking for ???

Racing rig or playseat compatibility:

Please ask the producer of your favoured product if the Fanatec CSR/Porsche Wheels are compatible.

The wheel itself can be mounted using 4 standard M6 screws which may not reach further than 1,5cm inside the wheel base. Please tighten the screws gently and not too hard!


The RennSport Wheel Stand Shifter adapter could help you to mount the shifter wherever you want with normal M6 screws. We commend to use the standard table clamp additionally to the screw fixation.

Measurements and weights:

• wheel - diameter: 30 cm
• wheel base - width and depth: 23 x 16 cm
• pedals - width, height and depth: 35 x 15 x 27 cm
• wheel - weight: ~ 2.5kg
• pedals - weight: ~ 1.5 kg

Thx! I found that link as well.

Problem is it doesn't mention the CSR Elite pedals and the shifter set weight and the wheel weight seems wrong.

These are the shipping wheights I got from Fanatec:

• CSR (non elite) Wheel: 5,6kg
• CSR Elite pedals: 7kg
• CSR Shifter set: 5,6kg

If the wheel weight in the link is correct (2.5kg) that would mean that the box and psu weigh a massive 3.1kg

The CSR elite pedals support page doesn't mention the weight:

Looking forward to seeing your rig in full motion :

Just finished the pot pivot arms and assembled the complete motor arms:

Very nice there, much better than mine as I do not have a drill press, just a shaky hand holding the drill. :rofl:
Yes, front mounted motors work well. I have trialed different front motor mount placings on several of my previous builds with wipers and the big motors.
Here is what I did with a another build (what?!? Again?!?), which is my current sim.


As I have not tested motors at shoulder height connection I cannot advise if there is any motion difference or less power consumption. There are other wiper - shoulder builds here on the forum, so perhaps PM those builders directly for advice.
Short of strength of gearing in wipers, they should have sufficient power to give you some motion, although, I ran my wipers at 23 amps max current to give decent motion, and had to put fans on the motors to cool them. I didnt break a wiper, mind you, I kept extra fat drivers off it, like over 110kg.
Wiper motors are always a good cheap start and then if you like move on to different motors later.

Also, a suggestion, get your hands on some extension springs of different strengths. I found adding springs, and put them in different spots depending on balance, helped alleviate some balance problems and also not only reduced overall load on the motors , but with wipers being a bit tender, seemed to chopped the gearing out on constant direction change. So a spring helped create enough of a constant load on it to reduce this.
Hi-jack thread time


Although, as there are metal gears inside yours, you may be ok.
Cheers, David.

Thx for your hints, construction pics and tips David!

Can't keep up with your builds That's the 4th I've seen so far (bet there are more)

Did an rpm test on the motors last night:

Fast: forward 55rpm / reverse 51rpm
Slow: forward 41rpm / reverse 41 rpm

Will start with the fast speed and if the rpm difference turns out to be problematic/annoying I'll try slow.

Built some very simple mounts for- and din't clean the motors because I want to test them thoroughly before spending a lot of time on decent mounts.

Yes its the 4th build, I am trying to resist more design changes, I even took all my scrap steel to the metal recycler's , I got $60 for all of it.
I plan to stick with this for a while. I have had to make job changes, so time is shorter during the day.
Anyway, good to see your sim is progressing. Just give the motors you have a whirl.
When I had wipers, I had the same issue, one a bit slower than the other and different speeds from forward to reverse. Although during gaming I didnt notice it. I always used the faster speed.
Cheers, David.

Took me more time than I hoped for, but managed to go from this:

To this (white pads are thermal conductive tape):

To this:

Together with some decent airflow this should do the trick of keeping them cool

Thx!

Made the pot mounts today:


Also wanted to build a test setup with a single motor on a plank, but ran into a problem during the mounting.

Due to the construction of my motor arm it can't make a full rotation because the head of the bold hits the motor housing.
Luckilly I noticed this before powering up the motors :

Back to the drawing board (as a figure of speech ) to create some more clearance :tape:

do a good job, congratulations

Lol, this project is slowly getting out of hand started as a low budget simple build plan but decided to take more care of the details than initialy intended.

Since I have to wait for my m8 to weld the u-joint I have too much time to think of new stuff :?

I found a cheap aluminum supplier for my new motor mounts (gonna add an extra mount with a bearing for moving the axle load from the motor to this point) and because they where so cheap I also ordered some extra aluminum for making my pivot adjustable. (you'll see when I get to that).

Also ordered some warnex today which is speaker paint for structure painting for my platforms.

On the parts of the platform where you can put your feet I'll place skateboard griptape to prevent the paint from wearing and people from skidding off

Next to that I decided to make a seperate box with the psu's, usb hub, jrk's in it (with spare room for a 3d jrk/psu to be 3DOF proof )

I'll keep you posted of course! Don't have as much time for building as I have for thinking about new stuff, but you'll see the updates when I made some progress.

Now on to the reason why I came here to make this post:

Since I've tried to gather the Fanatec CSR Wheel, CSR Elite pedals and shifter weight, but unfortunately didn't get a single reply on different forums I'm active on I decided to guess and hope that you guys would like to state if you think my guesses could be correct.

The package weights are the following:

• CSR Wheel: 5,6kg
• CSR Elite pedals: 7kg
• CSR Shifter set: 5,6kg

Since the wheel has a PSU, the shifter has 3 parts of which 2 are used at the same time and the boxes will have some weight as well my estimates are:

• CSR Wheel: 3kg
• CSR Elite pedals: 5kg
• CSR single Shifter with mount: 3kg

Gonna determine my balance point based on those weights and create my platforms accordingly and since my pivot will be adjustable hope this will turn out right, but if any of you have any thoughts on my estimates: Please share them!

Hi floriske.nl
I don’t have the CSR wheel but the Porsche 911 GT3 RS V2 Wheel - Clubsport edition - EU [PWGT3RSV2CSE].

The actual weight of the wheel is 3.165 kg and of the pedals 5.3 kg. (These pedals are massive!).
I don't have the shifters :cry:misunderstanding :cry:

Good estimate of yours!
Thomas

Thanks for the confirmation!

Since my pivot will be adjustable (in steps of approx. 16mm) I decided to take my chances on my estimates.

Last night I determined the approx. balance point of the seat incl. myself and a MS wireless xbox wheel as well as with the estimated weights, they only differ approx. 5cm so if my estimates turn out to be a few Kg off this will only result in the balance point shifting slightly.

Here's my final design for the platform (the dashed red line represents the bottom platform):

I used Deriy's motor mounting point distance

Theoretically, combined with my 5cm motor arm travel (10cm total) this results in a max platform angle of:

Pitch: +7.12 and -7.12° = 14.24° total
Roll: +9.46 and -9.46 = 18.92° total

Which should be enough to make me seasick (Special edit for bsft: :sickish: )

Edit: Rotation sample

that looks about right, now wheres the smiley throwing up :rofl:

Last week my aluminum finally arrived


And after a lot of drilling (3x per hole -> 2,5mm -> 5,5mm -> 8,5mm), countersinking (2x per hole -> both sides), rounding corners and sanding part of it results in:

The shorter pieces will be mounted on steel plates:

And the longer pieces will be mounted onto the above:


I have 2 of these parts but only mounted one for now because eventually my u-joint will be welded in between the two and the steel parts will be painted black after that.

All in all this results in an adjustable pivot for balancing purposes.

The unused aluminum is for the next step: The motor mounts

Tonight I found some time (very busy with all kinds of stuff except for my sim :thbd: ) to finish my bearing supports:



Once again sorry for the crappy pictures but I just don't feel like taking out the DSLR for them

Ever wondered what a disassembled wiper motor looks like?

Here you go:



On the photo you can clearly see the third carbon brush for the slow speed on the pcb (the 2 opposite of eachother are low speed, the one under an angle is for high speed).
I'm going to leave the ones for slow speed out so I have some spare carbon-brushes and one less wire (next to that it reduces drag slightly, being neglectable though I reckon).

There also are 3 brush/sliding contacts in the plastic part (not visible on the photo) which make contact between the center 3 pins and the axle gear. 2 of them aren't connected and one of them is for grounding the axle. These I'm going to take out as well since they are useless to me and cause unnecessary friction as well (also neglectable but why keep them if they are useless).

At first I thought I had 2 identical motors and opened up one to check if they had metal gears and they did.

Later I discovered the housings where a little different as well as the rpm. Today I wanted to disassemble one to see if they are easy to clean so I took the other one and unfortunately it is indeed different and has a plastic gear and less beefy rotor

Luckily I most likely found someone who has another one of the first type.

Last week I've spend a few hours on cleaning:



And painting the motors:



Unfortunately the silver paint (which I expected to be more greyish looking at the spray can's cap) shows all surface irregularities of the gear housing and the silver and the primer didn't really like eachother and there are a few minor blatters in the coat, but not disturbing enough to sand them down again

Cool, nice and shiny.... :thbup:
