Inertia Ration for External Axis

  • Hi,


    Do anyone know how can calculate the Inertia ration value for my external axis? (INERTIA RATION when define external axis in %)

    That is mounting on a table that designed by ourselves.

    The motor code is SGMRV-13ANA-YR11

  • With that motor, inertia is commonly set to 250% with an acceleration of 0.3 to 0.5 seconds.


    With the information provided there isn't enough to decide what calculation to use. Such as power transmission method, ball screw, rack and pinion, or gearbox.

    I know a thing or two, because I’ve seen a thing or two. Don't even ask about a third thing. I won't know it.

  • Thank you.

    the motor is installed on a positioner that designed by our selves.

    we don't use gearbox, we use belt to turn the positioner that workpiece install on it.

    please tell me with this information what value is better to set.
