    Hi there,

    I finally want to start my new project : 6 DOF for flight simulation (DCS) with Oculus Rift VR HMD.

    I read a lot of topics here but I still have a lot of questions :) it's hard to know where to start !

    How to choose motors ?

    1-I initially started with a 3 DOF Project, with 3 motors.

    For 3g of acceleration, 130kg to move, 0.3m/s of linear speed, I find that I will need 3*620watts motors. With a lever of 10cm I will need reducer to go at 30RPM.

    Are these hypothesis of 130kg to move, 0.3m/s of linear speed are fine ? or do I need other one ?

    2-Can I use these data for 6 DOF project ? with 6 motors ?

    3-Are servomotors like this one :

    http://www.schneider-electric.com/e...ey---20-bit-encoder---w-o-brake-straight-con/

    good for that kind of application ? I see a lot of people using DC motors for platform sim.

    4-Is it hard to connect xsim software to SM Drive ?


    Thanks a lot for your help :)

    I too would like to know about this. I'm getting started on this and I seem to be stuck on choosing a motor type.

    It pays to finalise your design and seek feedback on it via your own build thread, prior to deciding on what motors best suit your project in terms of power, availability and cost.

    SimCalc will give you a basic insight into how design influences what power is required for what sort of linear speed: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    There is plenty in the FAQs about design, DC and AC motors, plus control board options.

    I'm exactly in the same boat as you...I've been reading and learn a lot from many different forum to start my 3dof sim soon and it's hard to make a decision for me to going in one direction
    I'm still blocked to what's motor I should use before going forward with my blueprint

    I know DC is cheaper and easy for 1st build but the load and degree of pitch/roll is a bit limited for a flight sim
    I was thinking to going with a AC Servo motor/driver instead but it's look like it's a pain to connect and setting up with the ardino and xsimulator
    unless I fund a good tutorials
    anyway I will like to know as well

    Hi

    I think I will go for 6dof finally. Here are my final carac with 200 and 400mm heave.

    Do you think it's good before buying all the hardware ?
