    Hello, I hope everyone has been well.

    I am developing a linear actuator for a self-led coop work term (I am taking mechanical engineering at university) and wanted to survey forum users with regards to the typical performance they like to run their systems at.

    What I'm interested in is linear speed (mm/s), peak accelerations, stroke lengths, and anything else you might be interested in! To that end, if you wonderful folks would be willing to share your settings with me by copying/pasting the small survey below then I would really appreciate it. You can fill out as much or as little of the parameters listed below, and certainly feel free to add your own, as well as a description of how you feel about the performance of your rig. Any and all responses are appreciated!

    Linear Speed (mm/s):
    Acceleration (G's):
    Overall Stroke (mm):
    Typical Stroke (mm):
    Voltage (V):
    Max Amperage (A):
    Continuous Amperage (A):
    How does your rig feel with these parameters?:

    My Motion Simulator:
    AC motor, Motion platform
    Linear Speed (mm/s): 500mm/s max (3000rpm at 10mm pitch) . From my experience 5mm (250mm/s pitch is too slow.
    Acceleration (G's): driver ramps/smoothing used to limit this to around 2 G.
    Overall Stroke (mm): 800mm
    Typical Stroke (mm): will vary depending on application (Aircraft, Car, Roller Coaster, space ship etc).
    Voltage (V): 240VAC
    Max Amperage (A): 1.8KW servo motors x 3.
    Continuous Amperage (A): Ramp limited so that I can run three actuators off a 10 amp breaker.
    How does your rig feel with these parameters?: Nice :).

    @SeatTime's is what I would consider 'high performance', see here in action but also do read the entire thread to understand the evolution to @SeatTime's current rig: https://www.xsimulator.net/community/threads/seattimes-sims.11757/page-17#post-217701

    True, but as he was after a linear actuator with I guess a reasonable stroke length, many have now upgraded from 5mm to 10 mm pitch for the extra speed to limit any lag in simulating the telemetry data ('Silent Chill', 'Peacemaker' etc). Its the long travels that really require/use all that speed - 500mm + stroke.

    Thank you for the replies so far!

    Wonderfully novel use of three ball screws to achieve motion SeatTime, that is a really neat system. I see why your stroke is 800mm :)
