    Hi all,

    I have read some threads and I planned to DIY my 6 DOF 12V DC lever based simulator.

    I found someone use wiper moter and some one use worm driver moter, what is the difference? which is better for lever based simulator? and how much power/amps or something else is required?

    Now I'm search moter on-line, I found some moter spec as below, please who can give me some suggestion, thanks in advance.

    • Wiper moter with gearbox:
    rated speed after gearbox: 90 RPM
    ratio: 20:1
    torque: 12 N.m
    power: 300W

    Hi wiper motor and 300W? Can you share the source link?

    @Pit Hi according to your experience, is 12 N.m torque enough for 6 DOF level based simulator or not? thanks.

    I do not consider 12 N.m torque is really enough, I use 36 N.m on my 3DOF with assisted heave.

    It depends on the length of CTC.

    Hi, compared with 3 DOF, I understand each motor of 6 DOF system only required about half torque, maybe my understanding is wrong.

    and do you have some suggestion for motor and gearbox type? I see there are different type, like worm drive motor,
    planetary reduction gear motor, etc.

    I'm confused which type should buy.

    if with 80 mm CTC, is 12 N.m torque enough or not? or how much torque do you suggest?

    12N.m not enough for 80 mm CTC. Even 20 N.m not enough for CTC 65 mm.

    I think, need use 50RPM/18N.m with CTC 40-45 mm
