    My Motion Simulator:
    3DOF
    Good evening, after a long time wishing for it, I have decided to build my own driving simulator.

    I could settle for a 2 DOF, but the truth is I want it to have loss of traction. and I'm going to get it !!!

    At the moment I have placed two motors on a homemade bench to check that the electronics work. I have connected 1 and it works !!!.

    Then I put some pictures of what I have as a project.

    The Motors (those in the photo, missing 1) are 24 V and have a reducer attached, I hope they can move with agility.

    I'm going to put some IBT-2 H bridges and all of this will be moved by an Arduino UNO.

    The potentiometers of the motors are 100K and I have made them with the 3d printer some supports so that they are firmly attached to the reducer and do not move.

    As I progress I will comment on it and upload photos.

    Thanks for this wonderful forum.

    Greetings from winterfell.

    Hello!!

    In the previous post I was wrong, I was referring to the 10K potentiometer.

    Next week I will design part of the structure in aluminum profiles.
    I have also noticed that the motors I have are small for the purpose I need (60W each motor).

    on the other hand, I have decided to use good materials for the simulator.

    Do you know if I can use industrial 10k potentiometers?
    I am afraid that the ones I use, which are cheap, will break with little use.

    PS I have arduino UNO and IBT-2 mounted.

    Thank you

    If you plan on changing the pots I would suggest going for Hall Sensors, as they are a drop in replacement, have great resolution and life span, plus won't break if over rotated.

    I have been reading about it and there are those that act on different degrees of rotation, right?

    I had thought of a 180º

    for a driving simulator it seems enough right?

    THANK YOU SO MUCH

    Technically you could get away with 90 degree Hall Sensors, but it is cutting it a bit fine, so I consider 180 degrees is the way to go, as it gives a bit of headroom, something with these sort of specifications: https://au.element14.com/bi-technol...fs/sensor-hall-0-2v-20v-to-10v-pin/dp/2319662

    Thank you very much for the information.
    One thing, I'm looking at 24v motors with a good quality / price ratio, but the forum threads seem old to me. Do you know any web link of powerful motors with 24v reducer and good torque?
    Thank you very much again, this forum is incredible

    Before getting too far ahead of yourself please spend some time fleshing out your project ideas and goals, as things like design have a big impact on what motors and specs are needed. When it comes to motors local knowledge of international order tend to be the two main options, with the latter often cheaper but taking some time.

    Have a play with Motion Visualizer or SimCalc to get an idea of design Vs physics tradeoffs:
