    Hi, sorry for that stupid question :D .
    What ist the main advantage from a SCN5-Solution against a Wipermotor-Solution?. At the moment i`m satisfied with the wipermotors and don`t know the advantage from SCN5 Actuators, because i do not test a SCN5 Solution till now. Possibly someone has changed from Wipermotors to SCN5 and can tell some experience from that.
    Please tell me the important technical reasons for a SCN5-Actuator-Solution instead a Wipermotor-Solution, because i think about to buy a SCN5-Actuator-Pair.

    Hallo Michael,

    1) Sind schneller/kräftiger, wobei jeder User bisher die Geschwindigkeit heruntergedreht hat, um Rückenschäden vorzubeugen :)
    2) Die Auflösung ist um ein vielfaches höher und pro cm Wegstrecke können mehr Effekte abgefahren werden. Liegt darin, dass Dein Whipper motor [strike]nur eine viertel - Drehung macht[/strike] nur wenige Umdrehungen macht um Den Sitz zu bewegen. Der Schrittmotor des SCN5 dreht sich um ein Vielfaches in der gleichen Zeit.

    Wenn ich mich recht errinere gibt´s folgende Formel um die Umdrehungen zu berechnen

    ***** 360°*******************************Wegstrecke mm
    _________________ X Spindelsteigung mm x ________________

    3,6° Schritt ************************** Spindelsteigung mm

    Angenommen, die Spindelsteigung beträgt 5mm, kommt der Motor mit 100mm Weg auf 10.000 Gesamtumdrehungen. Das reicht, um auch ein kleines Steinchen am linken Vorderreifen zu simulieren :D Hoffe die Rechnung war richtig...

    Die beiden Gründe fallen mir jetzt spontan ein. Die SCN5 User sollten mehr wissen

    Grüße
    René

    Schmarn...der wiper motor macht viele (ca. 30 Umdrehungen afaik) für eine halbe Umdrehung des Hebels.

    Gruss

    Jup,

    hab nicht an an das im Scheibenwischermotor verbaute Schneckengetriebe gedacht. Ist ja kein Direktantrieb. Dennoch sind´s wenig Umdrehungen im Vergleich.
