I got the numbers from an energy calculator i found at www.1728.com/energy.htm . I can only assume it is an accurate calculator. used 2000lbs for the weight and 1.5mph for the low baseline and got 150ftlbs, and 3mph for the highend which gave me 600 ftlbs. Ijust went back to the website and...
Hello All-
Below is a picture of a cargo crawler I've been thinking of. Gross weight would be 2000lbs, moves between 1.5- 3mph, crawls on pavement or concrete. So far I've come up with aluminum tube welded frame with wheel motors at the rear, either motorcycle type or electric forklift type...
Does anybody know of an equation or rule of thumb for power decrease as load increases?
As an example an electric golf cart will go say 15mph with one 100lb driver. Put 4, 200lb people in it and it will go much slower, say 9mph. Is there a way to determine what that loss will be other than...
Thanks berkeman-
It's www.1728.com/energy.htm, forgot the .htm part.
The crawler will be self powered with an on board battery. I'm assuming if an electric forklift or pallet jack can run all day, then I should be able to get 90 minutes with some sort of industrial, off-the-shelf battery...
Hello All-
COuld someone please give me a primer on DC as it pertains to voltage, amperage and wattage. Specifically, if I have a motor that i need to run at very low RPM (50 -150), how does the motor compare across a 12v system vs. a 24, 48 or even 60v system. Do 60v systems run more...
