Abstract

PURPOSE:To simplify a circuit configuration by obtaining a feedback signal relating to the number of revolutions of a motor after directly converting into a DC signal from a frequency proportionating to the number of revolutions in the motor speed control device of a frequency feedback system. CONSTITUTION:The number of revolutions of the motor 7 is detected by a pulse generator 8 to send a frequency signal ff proportinating to the number of revolutions to a frequency-current converter 90 and the frequency signal is directly converted into a DC current signal. The output from the converter 90 and that from a speed commander 1 for the motor 7 are sent to a deviation amplifier 100 to control the rotating speed of the motor 7. In this way, an operational amplifier which was required for a frequency-voltage converter will be eliminated and a circuit configuration will be simplified by converting a feedback signal into a DC current signal from a frequency.
