ABSTRACT:
A speed control device for a DC motor includes a voltage maintaining circuit connected between the DC motor and a comparator circuit for maintaining the voltage corresponding to an electromotive force when a pulse wave outputted from a pulse-width extension circuit is at a level for off-operation of a switch element. Additionally, an average voltage maintaining circuit is connected between the DC motor and the comparator circuit and maintains in average the voltage corresponding to the back electromotive force produced in the DC motor during the time when the control pulse signal outputted from the control pulse signal output circuit is not at a level for on-operation of the switch element.
