My p/o/v is that the motor driver should be able to handle the stall current of the motor(s) and that the DC power source for said driver should be capable of delivering that current, plus the "overhead" load of the controlling electronics, without significant voltage loss and excessive 120 Hz ripple. I don't yet have a bench DC supply capable of testing the motors accurately, but suspect that a pair of can motors in a typical loco, wired in series, will not overload the Blunami board under "normal" operating conditions. The series connection should be OK if the loco is geared to run at excessive speed with 16+ V supplied to it, in "conventional" mode. A large can motor in a large steamer is another matter.
