Abstract

PURPOSE:To prevent the controlling accuracy of the speed controller for a DC motor due to the influence of a temperature from being deteriorated and to improve the responsiveness of controlling the feedback of a pulse signal by using a detected pulse signal outputted in a frequency proportional to the actual rotating speed of the motor as a feedback amount. CONSTITUTION:A detecting pulse generator 2 outputs the detected pulse Pd of frequency proportional to the rotating speed upon rotating of a DC motor 1, and a pulse duration output circuit 3 outputs a pulse duration signal B of the detected pulse Pd. On the other hand, a pulse duration output circuit 6 outputs the pulse duration signal D of a command pulse signal Po, and a phase difference output circuit 4 outputs phase difference signals +E, -E between the signal Pd and the signal Po. A DC voltage circuit 8 reads out voltage value information from a memory circuit 24 in response to the signals B, D and the signals +E, -E and applies them to the motor 1.
