    Quick question, i have a cordless drill motor that came with its gearbox (planetary gears) installed, im not able to turn the short shaft that it came with (only a little bit). could it be that im not applying sufficent torque to counteract the force produced by the gears?

    im going to try using a larger shaft and add a large diameter wheel or smth like if it was a steering wheel, could that help to move it without power?

    take in mind the motor works just fine driving it with dc power and also with an arduino and dc psu

    When an unpowered motor can be moved it is called being back driven, a low gear ratio and short leverage both contribute to a motor not being able to be back driven when unpowered.
