Actuator or motors ?

Hello everyone I'm new here and want to learn and eventually build my own 2 DOF motion simulator . So first question what gives a more accurate representation of what you see on screen actuator or motor ? . Sorry for asking this question most likely already posted somewhere on this sight if so please direct me. I am trying to build something like the Sim Experience Stage 1 . I made my first post in the misc. section so that post is really my first question. I'm was trying to find a parts list for my DIY journey.

Well this is what I thought as well, but as shown in this thread https://www.xsimulator.net/community/threads/scn5-strip-n-clean.9041/ SCN actuators use a acme thread which has a similar efficiency to a DC motor with a worm gear (around 40-5o% efficent). Not at all like the DIY actuators that use ball screws (around 90% efficent).

They use Multi start acme screws in scn5, they are more efficient than single start screws
But it won,t be more than 65%

Thanks all good information. I don't own SCN actuators, so was just going on what I could make out in the 'SCN5 strip and clean' photos, for the money just always thought they were ball screws.

Our sim project is looking at using winch motors, which is another option. A lot of the projects on here are lifting only a light cage where we are lifting a 9o0 lb cabinet add to that the weight of the player. The hardest part for us is to get something that is not over kill or worse something that is too weak to maneuver such a heavy device.

900 lbs +, I would be looking at AC motors/inverters and suitably rated gearboxes, but if you must, recommend purchasing just one winch motor, controller, driver, power supply etc and test it for speed/load and inertia moving capabilities.

Thanks Seat time, I appreciate any and all inputs. The problem is we are a school and a state one at that. This means that if you are working on a project to any level, you have to provide the entire cost associated, you also have to order all the parts. This is not the best approach and if I was funding this myself I would not do it like this.
