Abstract

PURPOSE: To readily adjust the speed depending characteristic of a DC motor by providing an arithmetic amplifier for adding a speed standard signal and a bias signal, and an arithmetic amplifier for multiplying the output of the previous arithmetic amplifier by the output of a speed control amplifier.
CONSTITUTION: A DC motor 3 compares the actual speed with a standard speed 5 at a speed control amplifier 6 to control so that the deviation of the compared result becomes zero. At this time the bias signal from bias adjusting potentiometers 29, 30 is added to the speed standard signal 5 set by a potentionmeter 14 by an arithmetic amplifier 3, the output of which is multiplied by the output of the arithmetic amplifier 13 by an arithmetic amplifier 40. The output from the amplifier 40 is applied to an amplifier 13 to thereby provide a depending characteristic at the motor 3. The timing for starting the depending characteristic can be determined by adjusting the bias signal, and the adjustment of the depending amount can also be readily adjusted by controlling the potentiometer 34.
