Hello, I'm poised to ask a question which is probably easy to answer. For my college project, I have to research and design a trailer mover which can pull a weight of upto 3000kgs. However I have been looking into a DC motor that can accomodate a peak torque of 250Nm. This has lead to a few slight problems, there isn't that many DC motors that can accomodate this kind of torque and the ones that do really aren't in my price bracket. So my question; Does it really matter about the torque? If high RPM = Low torque, then using a particular gearbox shouldn't I be able to use a High RPM Motor connected to a planetary gearbox or something and produce the torque I need?
