Abstract : A speed control for a direct current motor. A reference frequency is provided to a programmable counter which provides an output divided by a predetermined number. The output from the programmable counter is one input to a phase comparator whose output drives a direct current motor through a power amplifier. A tachometer associated with said direct current motor provides a second input to said phase comparator. A trans-resistance amplifier provides negative feedback to said power amplifier and determines the overall gain. (Author)
