    For the simulator in its current configuration, I do not ais need more powerful it asser cup my vertebrae:grin
    The day I will change it will be for another project;)

    I am thinking of building something similar in design however I want to be able to lift and move about 170kg and build it using 350w motors and use steel instead of aluminium.

    Would 350w motors be able to lift and move that sort of weight. Here are the motors I was thinking about using.

    Reference MOT350W

    Engine 350w 3000 rpm

    Torque output motor 1,1NM

    Reducer with oil bath, ratio of 50

    Output torque 40NM

    Speed 60 rpm

    If you use springs it can be done easily. It also depends on the lenght of your cranks.
    With only 3 motors and 3 springs there is almost 160kg on this one (cranks are 60mm) :

    Nice video - lots of smiling faces :thumbs. The following is just for info and something to be aware of when building a 'simulator'. if you use springs be aware that just like a car they will introduce oscillations/unwanted movement at certain (normally high) speeds which causes the simulator to not move in a realistic manner Ie. Not tracking the data that was actually sent from the computer. Just like a car these can be tamed with dampeners - unfortunately installing dampeners also bring their own issues - which I'm very aware of as I originally used them on my simulator and later removed. Not trying to knock anyone's build - just trying to educate the community that using springs also comes with disadvantages, not just the advantage of offsetting load.

    For a 3 dof in view of the capacity of the engines and the weight to be loaded with the inertia, springs are a necessary security. For a dof not obligatory, how much do you plan to axes?

    Will springs really be necessary for a 6 dof using the 350w motors I mentioned above?

    We never took the time to do a six dof but normally the springs will not be essential although advised (at least 3).

    I agree with you @SeatTime, no matter what you are going to add to help motors this will involve unwanted effects. But with a properly configured PID you can greatly decrease these effects and do not feel them what is most important :thumbs
