Abstract

PURPOSE: To prevent variation of a rotational speed of motor regardless of variation of a power source voltage by varying a duty factor of a motor driving signal according to variation of a power source voltage.
CONSTITUTION: An operational amplifier 10 issues a signal of a sawtooth waveform which is an addition of a signal et of a sawtooth waveform of a constant period to a power source voltage VBAT, and an inverting amplifier 12 issues a signal et' of a sawtooth waveform by inverting the output from the operational amplifier 10. A comparator 3 issues a driving signal for a motor 5 which has a duly factor based on a rotational speed command signal es and the signal et' of a sawtooth waveform. By this arrangement a rotational speed of a motor is maintained constant in spite of variation of a power source voltage by adjustment of a duty factor of a motor driving signal in accordance with variation of a power source voltage.
