    Hello guys,

    I have the project to develop a compact stewart platform (probably with VR so more light than with screen). I would not like to use linear actuator (too expensive), and no more AC motors for the same reason (& requiring also FV convertors...). I think more to worm gear (or other kind of gear) dc motors 12 or 24V, hollow shaft or double-axis to use one side for the position sensor, around 400 or 500W, and around 60 rpm. Brushless can be also an option. I also question myself about the noise level, and the slack (that can be an issue). I would like to spend no more than 150 or 200 dols for each motor (perhaps is it a dream...:()

    Do you have any suggestions, do you know good reference of motor, sellers, ... or do you know some posts related to this topic ?

    Thank you in advance


    No, no, no, no, no, this sucker's electrical, but I need a nuclear reaction to generate the 1.21 gigawatts of electricity I need

    If I was starting my project right now, I would have followed another path, but with the same motors.
    You can see my project here: https://www.xsimulator.net/community/threads/flypt-6dof-brushless-diy-actuators.10799/

    I would still use brush-less motors and calculate the position with the internal hall sensors. But instead of linear actuators, I would try a circular Stewart platform.
    Look a this video to get an idea:

    (He has more videos of the construction)

    One advantage of this is that you can make a big rotations in the vertical axis, something not possible with traditional Stewart platforms using actuators.
    Would love to see someone use this type of platform (can be really compact).
