I need help determining the necessary specs of a DC motor I need for a project? v/amps/hp/torque, etc? Answered
I'm a pure novice and know next to nothing about motors. I want to build a motorized platform cart to move some large items around the shop / yard. I want it to be capable of hauling around 800 lbs up a slight incline (10-15 deg.). speed is unimportant (in fact, slower the better probably). I'd like to do it as cheaply as possible with parts I already have or can easily acquire at salvage yards or yard sales. This will only be used on rare occasion and for very short durations so cheap and dirty is fine with me.
I have the frame (cart) including some 8" pneumatic wheels if I choose to use them). The part I'm stumped on is the motor, controller and whatever I need for transmission/gears.
Here's a couple of very expensive commercial options which are overkill for what I need (and far too pricey!), but at least it gives some idea of what I have in mind.
This link includes some detailed specs on the motor they chose to use....
I'm not sure what the relevant specs I need to be concerned with are. For example, I have a bunch of 18v dewalt motors which I understand can be over-volted but does that get me the hp and torque I need? If it's more amps I need than what the little dewalt motors will give me, could I use a 12v car battery and a starter motor? If so, what would I need to use for a controller and drivetrain?
I think what I need is a very low rpm/high-torque motor, but don't know for sure. And if that's what I need, what are some common applications that they were used in that I might find such a motor?
any help or ideas would be appreciated
