I know how to measure Km, but I already know Kt from the datasheet and according to some motor calculation guide's I've found online, they say you can know one from the other by using the relationship:
Kt (oz.-in) = 1.345 * Km (V/1000 rpm)
I checked this on other motor's datasheets that give both Km and Kt, and the relationship is fairly accurate. So I'm wondering why? Where does this relationship come from?
Where does this 1.345 value come from? I'm trying to workout what the units of this factor would need to be to give me some kind of clue, but does anyone have an explanation?
