Because I'm buying off Ollie has he has been fantastic with me and I feel he deserves my money...
THANKS i'LL TRY
Since earlier questions, I did some web searching and found some answers by myself.
Q1,Q2) I found acrylic plate 5T can be used with laser cutting for the back panel.
Q3) I've spent huge time finding the port bracket but failed. Any good suggestion?
Q4) For the motor power and ESTOP, I decided to use Neutrik 4pole/3pole connectos. The reason for 2 different types is to avoid any mis-plug-in.
If there is OSW owner with CoolerMaster Elite 130 case, it would be very helpful to share how to layout each component and wire in the case.
Maybe someone can show very nice layout also considering EMI.
I just get to have one more noob question. I have IONI HC drive which is different than IONI PRO explained here.
In this case, can I use same schematic for wiring? Maybe just FW is different. Correct?
Any news from Granite Devices?
btw. could someone explain me, how it is, than ARGON sends AC current to motors, while IONI sends DC current?
Since MIGE is an AC servo motor, output from both Argon AND Ioni to electric motor is tri-phase AC with variable frequency and voltage.
Input is different, with Argon you don't need an external DC Power supply because it is embedded.
So you can feed Argon with 220AC but IONI needs DC.
In the tech spec. for IONI Pro HC I only see:
- Motor voltage rating 12-60 VDC
- Motor current rating 0.2 – 23A
No mention about AC motor voltage, while for ARGON drive you have:
- Integrated AC mains power supply: single phase 85 – 264 VAC 50/60 Hz, 0 – 16 A
If IONI in fact can output AC voltage to drive an AC motor, why there's not a single word mentioned about that?
Of course, I sent the question to the manufacturer over a month ago and never got any reply from them.
Yeah, whatever...that voltage rating is for BLDC or Stepper.
For IONI specs pls refer to this:http://granitedevices.com/wiki/IONI_specifications
As a matter of fact if you feed MIGE (and Lenze and Kollmorgen) with DC it wont run, since it is an AC motor it needs a "rotating electromagnetic field" to rotate, and you can have that only if you feed it with AC current.
Yes, I was using that site... if you actually look into it, you won't find any information about AC voltage rating.
In the "Motor Output" section, the line "Maximum effective motor phase output voltage" reads : "3-phase AC motors: Vsupply*0.775 V RMS (phase-to-phase)"
So in our case (48V DC power supply) the IONI will feed the MIGE with 3-phase @37.2 VAC RMS max.
Voltage is modulated from 0 to 37,2V in order to feed the necessary current to obtain the requested torque.
Modulation of rotational speed is obtained through frequency variations.
OK, that's what I couldn't grasp - that "Vsupply", which I was expecting to be as AC output voltage rating provided somewhere, is actually DC input. Thanks for explanation.
I've embarked on the journey to build an instance of the OSW using the IONI Pro drive, "Small" MiGe Servo motor and STM32F4Disco controller as well as the wireless wheel buttons side project (nrf51822 BT modules).
An enormous thanks to Beano MMos, Martin Ascher (and many others) for the selfless hours and effort put in to aid commoners like me to stand a chance at successfully completing this project.
There's so much info on the iRacing forums it's worth being a member just while you do your build.

Thanks for the pictures. They are definitely helpful. As you suggested, I'll consider being a iracing member for the moment.
Yesterday is arrived mine osw from Ollie, simply perfect! The shipment is arrived in 2 boxes and everything was very tidy and sealed.
So, after dinner, I started to mount this beast, and about midnight everything was ready.
I only tested for about 10 laps but it's another world compared to my "old" t500.
New member price is only 1 Month : $6 or 3 Months : $15 you just need a new email / Gmail address to get this if you already been a member.
Hi OSW owners,
Can you please give an idea how(what is used) the power switch and wire is connected in below picture? The picture is captured from "Steps to perfection" by Troy A. Schulz. It seems that soldering not used but it' hard to know due to the tube surrounding the connection point. I'd like to follow this method for the wiring.

It's just a female spade crimp
Thanks again. I found exactly same one using the key words. Now I need to find this in my area.
Mine arrived this morning.
Very well packed and many pre-connected cables to help the electrically inept.
I've been slowly and carefully connecting everything. With Ollies pdf file its been quite straight forward.
Ready now to get the power lead (PC type) and test it.
Then I have to try to recover my nearly botched Formula Rim conversion. I have now purchased a temp controlled soldering iron and have the appropriate solder, some thin copper film and magnifying glasses on order.
You might need blue one's depending on your wire size, any car part shop would sell them as well.
Separate names with a comma.
