    Today i gave the first step to building my first simulator.

    I improvised some parts, now i need help with motor specication.

    Plese look the motor specification that i send. And help me do a choice

    Theres a BIG price difference, are you planning to run 24v or 12v through these motors.
    As for cost, Id guess the more expensive, the better the quality, but the "wiper" motor certainly looks good.
    Also , whats the pivot? Looks like a cut up CV joint

    Have you finalised a design and can you post a sketch, even if it is hand drawn, so we have some idea of what you plan to build.

    Can you also post links to the actual pages for the motors rather than images, so we can poke a bit further into their specifications.

    I think run in 24v, because i have a little difficult to find the motors 12v with similar specification like the motor 24v.
    yes the pivot is a CV with water pipe.

    So do you plan a compact design with the motors driving the base plate or is there more to the frame for a shoulder mount design?

    Yes,
    I'm planing build a compact with the motors driving the base plate. I did the draw, but i'm very terrible with drawing. look and try understand.

    If you can hook the motors up higher it would take some strain off the motors and the wiper motors should do it.

    Otherwise you may want to consider the more powerful motors if mounting to the base with little leverage.

    I will Try use the wiper motors, the distant the base at the chair it's not small.

    Hello,
    Yesterday i found a used motors in my city, is very cheap compared with the new motors.
    I'll make some adaptations for the potentiometer.
    Look the motors i found.

    @bsft it's a good ideia.

    Somebody have one schema of the H bridges?
    I have difficult to find in brazil the H bridge to high current.
    Thanks.

    A desk racer motor setup will work with wipers, but balance it all right, and make the motor connections higher up. Preferably make sure the driver is not too heavy as well, like under 100 kg

    test each wire first before you start opening casings, you may find a common earth on a wire. I know I did not open the casings when I used wipers, I tested the wires and most of the time, found the earth wire.
    But yes you need to earth isolate.

    @bsft Ok, it's no problem i Have 70kg.
    i found the the pin that i think is the ground, my motor is different it doesn't have pin to two speed.
    Look the image, in the red circle is the pin i think the ground, and in the black circle only contacts to the car know where the wiper motor is

    @Bordiin , I dont use wipers anymore, but it looks like, from the photo , it might be that. Only one way to find out. Disconnect it and test.
    If you are 70kg, then say using a seat thats about 10kg would be fine.
    Go forth and build!

    P.S , Im 85 kg and used a 15 kg seat on a seat mover originally with wipers under the back. I now know, a desk racer mount is a lot more efficient

    looks good @Bordiin , however, higher up for the motors would be better on the seat part of the frame

    Follow my news modification!
    @bsft in the conection on seat frame i need the moviments? or can i leave the fixed axis?
    Another question you have schema to H bridges?
