    MarcoMade,
    it gets rather hot. Also need to make holes for ventilation. Checked after the game, don't know how much was in time, smth like for half an hour tests or a bit more, it was under 50C. The motor housing. Rotor should be smth like up till 80-90 may be. But I guess it gets some more if take a greater time. As usual, simply put. With the same power, the 540 motor get smoke, with 130c of rotor and 80c of the motor housing, with just one lap, in "dd" mode)


    With a bulb, it has less ffb ofcourse, but playble. Wanna try with 1-1/5ohms resistance on it. Checked with 25w 25ohms one, but that is too much. Had small resistors only to check the value amounts for it, came up with that numbers of 1-1/5ohms. Also to try some other power supplyes ets. But the only right way will be to make a good cooling.) The ffb force amount without current limiters is great. Especially with a smaller and lighter wheight wheel)

    Checked the torque test and a wheel under 12V12.5A Power supply appeared to be of having - 3.67 Nm of force. I made units conversion of the obtained data measured not with 1 meter lever of force, but with 7.5cm force lever. That has 5 kg at that applied point of measurement, fastened just right on that gear sprocket)

    With 12v33a - 5.5 Nm of force.

    well I applaud your ingenuity, but I have to say that bicycle chain is the loudest thing i've ever heard!!
    I'm interested in your arduino circuitry though. I would like the know the simplest easiest way to do one of these and this looks like it. So you basically just have two arduino thingies and you set one of them up as a controller and the other as an encoder? i dont get it.

    Switched to mmos.

    Made enclosure for STM32 & Arduino. Axis are connected via usb cables.

    Level of Ai 120%. Low agression.
    Powerfull FFB, motor takes 12A, with rated 14A. Good result with no super cooling of the motor to run it.

    Hi Sieben,would you happen to know the wiring diagram for the VNH2SP30 and the Arduino Leonardo using EMC firmware?
