| (...) Ah, thank you - so running two stalled train motors would exceed the NXT output, but running one train motor up to a stall conditions should be fine. Out of curiosity, along with the output limitations on the NXT (1 A) and RCX (500 mA), does (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

| (...) Some precisions here: - NXT stall current is 2A but only for a short time: internal thermal protection will trip at a current much lower than that (exact value depends on temperature and overload duration). A practical value is about 1A - NXT (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)
| | | | | ARM Assembly Language Programming on NXT?
|
| Hi, I just stumbled on this newsgroup/website while searching for kits for teaching Assembly Language programming to undergraduate students in Comp. Science in an interesting (interactive) manner. I'm primarily interested in the ARM instruction set. (...) (19 years ago, 8-Oct-07, to lugnet.robotics.nxt.nxthacking)

| (...) So it sounds like a single loop should be no problem under most situations, since I'm not sure I've heard of anyone running three motors on a single train (there's the same issue with how much amperage a power regulator can push). (...) It (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

| (...) Stalled, the train motor pulls 950 mA, while the stall current of the NXT motor is a whopping 2 Amps. So a single NXT motor output should easily handle a twin-engine train loaded to the point where it stalls the engine(s)... there's the matter (...)
