Great idea... but how much current should I allow through the motor when it
is stalled? And how much time should I let pass between tach pulses before
activating the stall detection function in the first place? What about if
the commutator is already hot? What about different size motors - surely a
big GE 11" can take more stall current than a little 6.7 incher?!
Etc. and so on.
