ABSTRACT:
A current limiting circuit, for a serial commutator motor, that monitors the flow of current through resistances chosen to model the motor, rather than the noisy flow of current through the motor itself. Current for one of the modeling resistances is derived from a tachometer on the motor and is thus proportional to motor speed.
