Thread: contorlling a pair of motors

  1. #11

    Default helpme, superchiku

    i have a robotic gokart that i built and am planning to use a servo motor to activate a simple drum brake by pulling a cord with the servo horn. Is a standard futaba enuff or should i go for a linear solenoid actuator?
    please help

    Futaba 3003 is not enough.

    Calculate the approx torque you might require.
    the torques that are mentioned in the servo are the stall torque, not the typical safe running torque.
    .... I didnt do it ! ....

    in simple terms, the torque delivered at stall. Run a servo motor, hold it (that the horn is no longer in motion) (not for long ) and the torque you feel is the stall torque.

    OR, for a horn of length 1cm, 5 Kg suspended at the end, and if the motor stops.. got it??


    And, if it were a 1 Kg weight suspended at the end, the motor would still rotate, or run.

    hope you got the idea.
