    Hi,

    i'm atm planning my motion sim(frex style). for actuator i've chosen the mirai scn5 100mm. now i wonder how much load you can put on them. i adjusted my brake pedal so that max. brake pressure is reached about when i step with 30 to 40kg on the pedal plate. i attached a vid, you can see that the standard frx rack is not rigid enough for this pressure.
    now, with the scn5's attached to the rack: on full braking power, will they even move me fordward on braking if i use full brake pressure? or, in worst case, will i push the rods back in the actuator?
    what's your experience on this? can the scn5's stand or work against this force? do they have enough power?

    Hi,

    thrust forces more than 10Kg per actuator can destroy it permanently. So you have a max of 20Kg to play around. You could modify your pedals, so that the force of your pushing foot doesn´t show to the bottom direction of your platform. When you hang up the pedals so that you have to push the pedals away from you and the force vector goes nearly straight and horizontal to the pivot of your seat the leverage is to small to push the seat against your scn5 with more forces than 20Kg. That should do the trick.Hope you understand what i mean without any sketch.

    Nonsens, a motor/actuator stall does not destroy anything permanently...

    i am not a mechatronic student, but what is about torque and current if they exceed the maximum limits of the actuators occassionally? The motors can overheat and damaged, can´t they?

    I dont write that they must.

    I would prefer that you explain your conclusion and not only say nonsense.

    That makes no sense and doesn´t help me and other people.

    Overload and overheat protection. Overheat is error code E0 and overload are error codes (D0,D1,D8)
