    Hi everyone,
    I'm building a 2 dof sim and I tried 12v winch motors for my platform but it's not looking good.
    First, when I step on the platform, the motor doesn't lock and it's moving under my weight.
    Second, there's some slack in the gears, so the platform is not stable.
    I already have a motor controller a a huge car battery charger, so I would like some good 12v motors to replace those I have.
    I found a lot of motors on the net but I can't figure what power or torque I need.
    The platform will be quite heavy since it's a combine plane and car sim (see the enclosed picture showing the platform without the dashes and steering). It,s on a universal joint

    I'm in Quebec, Canada so I would like to buy in Canada if it's possible. With the exchange rate and customs, it's too expensive!!

    Thanks for any advice, regards.

    The motors required depend on a number of things, including design choices and desired performance.

    Tools like SimCal can help you get your head around the tradeoffs in design Vs physics: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    Here are 2 options in Canada:

    Another possibility is new or used wheelchair motors, which are available in many areas of the world.

    Thanks for the info.
    Wheelchair motors are usually 24V, can I use them at 12V?

    I think I got my answer, it would reduce the power by half! So, I will find 12v motors.
