This question is part of a long-winded way of working out the maximum working-under-duress current-load on a 3S Li-Ion battery from a 10.8v/12vMax Dewalt Drill.
The replacement motor for the drill is a Mabuchi RS-550VC-8518. I've hunted high and low for a data sheet but the motor seems too old to have one available. Various listings I've found for these specific motors on E-Bay and the like list the stall current at any where from 3.0 Amps to 10 Amps (with no torque figures given...), while the closest wind I can find on Mabuchi's site (RS-550VC-7525) is rated at a wooping 85A/549nM.m stall and a similar Kysan motor (RS-550SH-7524) is rated at 32.4A/117.6nM.m stall.
Firstly, can both the figures for the RS-550VC-8518 and RS-550SH-7524/7525 be correct? ie: is there something about DC motors at this scale that could account for such a huge difference in stall current with that amount of difference in wind spec? (I'm more used to 130/180 sized motors...)
If not, which figure is more likely to be correct? 3-10A or 32A or 85A?
