    I got given some coils a few days ago and o wondered if i could use them on a sim

    They have a pull of around 200N at 4 amps

    The coils look rugged and may take more current / voltage

    I rigged up an arduino and a linear pot with a st motordriver and the smc3 software

    It works !

    The motion is only in one direction, the rubber gaitor pulls the plunger back out.
    I will fit a spring to push the coil back out.

    If there was a magnet on the plunger i could drive the motor in and out

    If i'm correct coils will not stop in degrees only full in or full out.
    It would make a very violent bumpy ride lol
    I will be following to see if you get the coils to work, good luck.

    no they can be stopped in position depending on how much current you have

    the coils i tested were pull only and returned using a spring

    i have since ordered some magnets so the coils can push and pull :)

    I not sure how well it would work due to the current needed to hold the rod in place at different intervals.
    Maybe if you had springs on both ends or multiple coils for each amount of travel you want .
    I wish you all the luck with your project and hope you get it to work the way you want.
