    I know it's highly off-topic, but I just don't want to create a whole thread to ask this:

    Just how powerful are car wiper motors? If I attach it with gear ratio 1:16 or so, how powerful would it be?

    I'm dissatisfied with my steering wheel FFB power and seeing how "soft" methods only yield minor improvements, I want to give it a radical motor upgrade, along with complete PCB upgrade (I'm pretty much replacing all internals, only keeping frame, shell and the wheel). Will it be just powerful enough to maybe simulate real forces? Or would I need two of those? Or more?

    You think your belt is a little loose and needs tightening? Just for the sake of more accurate actuator position readings. Would be best if it was directly connected to it via gears.

    Just make sure there's means to adjust it.

    Have you bought this lever for both sides of each motor and the Axes ?
    your motor gearbox have hollow axe .

    So far I've bought Aluminium Flat Bar
    Width 50 mm
    Thickness 25mm
    Length 1000mm

    It's still not ready...
    It should look as follows .I do not have determined length.

    Where did you get the idea of the limit switch ?
    thanks

    Hi :) @misoswan ... Feel free my friend to ask and know as much as you can for what is the best for your chosen platform ... and for information about the limit switch :
    They are used where there is any possibility for a mechanical damage if the control system fails .

    Look at this video and pause at the 00:05 & 00:08 for the upper and lower limit switches ...
    There are 2 black switches like the photo below placed up and down the motion range and connected to the VFD to stop the motion and prevent any mechanical damage ... which is not needed in your platform .

    You can connect the limit switches to the stop function of the vfd drive but then it won't auto recover the motor position. The method I mention on the link above actually just blocks the motion beyond that particular direction towards that limit switch while allowing the vfd drive to remain activated to drive the motor back to other direction with no "error flags" to lock the vfd drive.
