    Hi
    Electric actuators are usually expensive

    Once I tried uses engine of car's doormat but he was behind weak
    Now I built own Electric actuators
    It is trapezium screw and electric engine from car's radiator.
    It looks this so

    I think that one should to match suitable inclination of screw and strength/speed of engine.

    Did someone make something similar?
    What are your ideas?

    Hi Jarek

    Hey this is a nice and compact linear drive solution! If I had the tools to make something like this at home, I wold definitelly make them!

    Good work Jarek,
    Do you have some performance numbers for your actuators? Like speed in mm/s?

    I do not have interface
    I tested only manual, I used battery 12V and 24V It looks well
    I think above use of 2 AC engine or different screw
    I want to test earlier this what do I have

    Can you post some more pictures? Including some of the overal contruction of your simulator, like the one on your avatar!

    Can you measure its extension, retraction speed? Even if you power it manually...

    If it fast enouph then it could be nice and cheap solution.

    This is not full speed, batteries are not full loaded.

    Wow, thats much faster than I thought it would be!

    Could you tell me the pitch of the thread/nut?

    That was very promising! I saw some threaded rods at my local hardware store, maybe I'll pick up a few and make a similar test construction. Good work! :top:

    From I what I see in the video, your linear actuators are really fast!

    Good job!

    Can you measure their kg performance (ability to lift weights)?

    WOW, very fast. Do you powered with 12 or 24V in the video? I think your actuator is a well done alternative to the frex´s ones.

    Unfortunately in poland the trapez... are expensive same as in germany.

    yes...very well done

    I watched your video and are surprised as well at the speed. I never thought of using a radior fan motor but I bet it turns fast. Those are made for 12V but are you running 24V at it?

    also not sure on your mechanics, but it looks like you welded the end of the motor shaft to the threaded rod?....and then are threading it with some parts welding in place so they pull solid brackets along?

    ....was wondering what parts move and what parts are stationary ....was trying to figure it out from the picts

    Regards

    Great job, respect ! It´s very fast (too fast) and makes less noise than my frex...
