You can swap motor cables so it can rotate the opposite direction. If you do it right, the motor will center it self and on LCD you will read a value near 500 for the potentiometer reading. On your final cockpit cockpit mounting it behaves opposite than expexted you could invert the potentiometer +5v and Gnd connections or just invert the software axis on profiler...

BTW, it that a 10-turm potentiometer? You should use a simple 270degree for the way you want to connect it... The motor will rotate only 150-180 degrees after all, in a simforceGT sim...

Code: Select all

I think a mulitturn pot connected via gears directly to the motor shaft should give more accurate positoning than a 270deg pot.

The difficulty is with a pot connected to the shaft, is to find a matching gear ratio for the pinions.

@Michael
Did you selected the pinion ratio by calculation, or did you just connected ones to trial&error it?

To determine which gear transmission ratio is needed for the pot pinions, you need to know how may motor shaft revolutions the ww-motor does for a half crank revolution. Then devide the result by 10, and you know the correct gear ratio for the use of a 10turn multiturn pot.

I took over it from Elektronicsjack Simulator and it is a 10turn multiturn poti. HERE you can see and read it. Gear Ratio 1:3 (10 gear wheel teeth on Motor and 30 gear wheel teeth on Poti). I don`t know if this right

Oh, I see... You connected the pot on the rear end of the motor!!! My wiper motors doesn't have their rear end exposed like that!

Its fine then I guess to use a 10-turn pot as the motor itself will rotate many times before the gearbox turn even half the output axle...

Di it work anyway? Can you post a video from its behavior?

Meinst Du jetzt wie oft ich die Motorwelle drehen muß, bis ich eine halbe Umdrehung auf dem Potiritzel erreiche oder eine halbe Umdrehung vom Arm des Wischermotor?.

eine halbe Umdrehung vom Arm des Wischermotor

Jo, das meine ich.

[Michael N.]

Ok Christian,
habe mal gezählt. Also ich brauche so ca 28 Umdrehungen am Motorritzel damit der Arm des Wischermotor eine 1/2 Umdrehung schafft. Also sollte ich mit der Kombination von 10er Ritzel auf Motorwelle und 30er Ritzel für das Poti richtig liegen.

Hi some News .
It is not ready now but i have make a first movie from the first Movements of my Simulator . I think i have to turn off the light in the next Video , because there is nothing to see from the game on the screen.
Game is Rfactor with the Porsche 07 Mod, i use the Rfactor Profiler-File from DONDOGAN (it needs some more tuning for my setup) and set both KP-Parameter to 20.

Hi Michael,

Great video!! I like seeing all these details. Such videos are needed in order for starters to know what goes where!!



KP set to 20??? Isn't that too high? It will be just ON and OFF then, without any acceleration feeling!!! I don't recommend the use of KP setting larger that KP10 as it losses the acceleration action.

nice video
looks good
