Abstract
PURPOSE: To provide an improvement of characteristic, by such means that only in a prescribed narrow range before and after correspondingly to a period in accordance with the designated speed given by a rotation detected signal, a frequency- voltage conversion be processed to operate a speed control of motor 9, and if not of this range a prescribed control voltage be given.
CONSTITUTION: Rotational speed of a motor 11 is detected by a detector 12, with a signal, converted into voltage by a pulse generator circuit 15 through a waveform shaping circuit 13, divided into two signals of SP, RS-P. The signal of RS-P is outputted at a certain length of time delayed after the output of SP, and given to a saw tooth generating circuit 16 and timer circuits 17, 18. An output from the timer circuit passes through an inverter I1, I2, with outputs of SP and "and" taken in an AND circuit A1, A2, and a DC output VF obtained from a signal given to a sample holding circuit 19, and an operation of motor driving circuit 20 will make a speed control of the motor 11.
