Linear actuators for mechanical project

  1. Dec 16, 2012 #1
    Hey guys, I was wondering if you could help me out here. I'm working on a project that needs two fast linear actuators which I'm planning to control with the Arduino logic board, but I can't seem to find anything that suits what I need. Here are the specs.

    -Type of actuator: Linear
    -Minimum acceptable speed: 100 mm/s
    -Minimum acceptable load: 5kg
    -Input: Signal from Arduino UNO logic board
    -Frequency: Approx 10 Hz

    I would appreciate any help that you guys could give me. All the actuators that I've found online are either too weak or too slow.

    Dependent on the duty cycle required you could possibly overvolt http://www.servocity.com/html/25_lbs__thrust_linear_actuator.html
    these @ 24VDC and get the 100mm/sec required.
    If the actuators need to run more than intermittently, I would contact ServoCity about their recommendations. They've been easy to work with for this sort of thing in my experience.

    Max travel?

    This looks like it will work:

    You can wire up a DPDT relay for each actuator to be controlled by the Arduino. Though with the 10hz signal I suspect you'd be better off with something like a high-current analog switch IC. (high-current solid state relay)
