    Hello,
    I'm trying to build SFX-100 actuators using stepper motors. What are the requirements (torque and RPM) of the motors to obtain a speed that is not necessarily high, but rather correct, even acceptable?

    Thanks in advance,
    Tintin Boulsard

    Thanks.
    My budget is very low and I don't need fast and powerful actuator. I just want more realism but not a lot. My question was, what are the minimal torque and RPM of the motors on SFX-100 actuators, to obtain a low speed but a torque enough high to support 50kg (per actuator).

    Thank you.

    Thank you.
    It is very interesting. It helps me a lot.
    I've found the solution to my question: by dividing the distance to be covered in 1 second (ex. 250mm) by the pitch of the SFU1605 screw (5mm), I can deduce that it takes 50 turns to raise or lower the rig of 250mm. Then multiply 50 turns/s by 60 seconds, and you get the rpm needed to move it 250mm (3000rpm). I haven't yet calculated the engine's minimum torque; I'll let you know.

    Thanks,
