    I'm looking to buy some motors for 3 DOF and I need to figure it out. Does anyone have any experience with dump truck tarp motors, 12V, 50:1 gear ratio? I might be wrong, but the motor might be about 600W and 40+ amps. My only concern is that 40 amps, even using an IBT-2 driver, is way overkill. Are they really 600W motors, and do they require over 40 amps? I would prefer the motor to be less power hungry and more efficient. So far, I can't find many motors with 50:1 gear ratio in USA from Ebay. Many motors, like wheelchair Jazzy motors, with an unknown gear ratio.

    thats a lot of amps - however there are other types of DC motor drivers that may work

    do you have a link to the Tarp motor ?

    it will only use 40 amps if it is working hard

    some powerful motors there !

    with that much power, you will not need a 50:1 gearbox

    I think this may the same as the very popular Crab Pot/ Sawmill motor. https://www.ebay.com/itm/354052076387

    It’s “PG parts” but I think he just changed the name of the store. These are widely discussed at this forum if you search for the right thing. These have plenty of torque but I doubt you would ever pull that much current unless you were jammed.

    I considered this motor but did not like that the axel was not coupled well to the motor hollow shaft. I bought motors that had a key for the shaft and a heftier gearbox.

    “3 axis rig” is ambiguous. Is it 2 axes, a ujoint and traction loss axes or do the three motors lift the entire rig?

    Ended up ordering 3 wheelchair motors off Ebay. Looking to buy a 34amp 24v power supply and I don't know if it's enough for 3 motors.
