    In 2DOF project (https://www.xsimulator.net/community/threads/2dof-on-jrk12v12-poland.14590/) I decided to add Traction Loss feature.
    I bought Power Steering column with motor from Opel Corsa for 15EUR ;-)

    I could not find any parameters and I decide to make some measurements and share with You.

    Power Supply : 12V DC
    Gear ratio: 16:1 (it is possible to rotate shaft by hand)
    Fuse in car installation: 80A
    Speed without load: 130RPM

    I decide to add load: 1m wooden arm and 2kg hammer on the end. Motor handle this without problem.

    During this test I measured peak current :

    Final Conclusions:
    Torque which motor could handle is ~20Nm, with this small ratio gear it is nice result.
    For general DOF axis projects I rather suggest to use 2:1 additional gear (ex. teeth belt wheels).
    Another idea is disassembly motor and make adaptation with cheap worm gear 30:1

    Power consumption is really big. Soon I will try to drive it by JRK 12V12.

    These motors look pretty good for price and power

    would also work well in a g-seat I think
