| I apologize for the inability (both in time and mental stamina) to read this entire thread. But I feel the need to offer an easily-backwards compatible alternative to the power supplies thus far mentioned... No need to recharge underpowered (...) (19 years ago, 8-Oct-07, to lugnet.lego, FTX)

| (...) Philo kindly corrected me, pointing out that the NXT outputs are regulated down to 1 A, so you couldn't run a dual-truck train all the way to stall. You could still get a good bit of the way there, however. Does anyone know what the peak (...) (19 years ago, 8-Oct-07, to lugnet.lego, lugnet.robotics.nxt)

| (...) 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)

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 (...)

Some people will switch to the new battery trains. (...) (19 years ago, 7-Oct-07, to lugnet.lego, FTX)
