    My Motion Simulator:
    2DOF
    Hello everyone, I come here to share with you my project to build a motion simulator with 2 dof.

    I'm using for the circuit:

    Arduino one;

    2 24v motors with 82RPM;

    2 BTS7960B H-bridge modules

    2 hall sensors

    2 switched sources

    I'm basing myself on this project

    For the case I am using a plastic tool box with a lock.

    The electrical connections between external and internal will be with powercon speakon connectors

    I'm still designing the cockpit structure, trying to create a lightweight and adjustable structure design.



    Materials for the structure I only have:

    1 universal gear shift joint

    1 m8 threaded bar
    4 label terminals with M8 thread

    The project is still in development, there's still a lot to do, but I'm happy to be able to move forward.
    Problems:
    When I tested the motor with SMC3Utils, the motor stopped when turning the hall sensor in the same direction as the motor shaft and would no longer start. So I tested it by turning the sensor in the opposite direction of the motor shaft rotation and with that the motor started to change the direction of rotation, when I turned the hall sensor to the left the motor turned to the right, when I turned the sensor to the right the engine turned to the left, but at no time did the engine stop or shut down. I don't know if it's a problem, because in most of the projects I've seen here with you, the hall sensor is rotating in the same direction as the motor shaft. If anyone can give me a tip I would appreciate it.
    Should the hall sensor or potentiometer rotate in the same direction or can we use a gear rotating in opposite directions?

    Well, to update the project, I'll post it here with you....thanks
