Abstract

PURPOSE:To realize the control of the rotation of a DC motor with a brush with a tension servo-manner element by feeding back an output detecting the periodical pulse responsive to the rotating speed produced during the current waveform of the motor to a motor driving circuit. CONSTITUTION:A speed control circuit 12 differentiates the commutator noise presented at a resistor R1 of a reel motor driving circuit 11 by a differentiator 122, is amplified by an amplifier 123, thereby obtaining a differentiated amplified output. This output is transformed into a sawtooth wave output via a switching unit 124 and an integrator 125, and is converted into a rectangular wave output via a comparator 126. This output is converted to a DC output of constant level via a level shifter 127, a buffer 128, an integrator 129 and a filter 130. This output is applied to a controlling transistor Q0 in the reel motor driving circuit 11 via a phase compensator 132.
