Abstract

PURPOSE: To ensure an easy control for the loop gain of the servo circuit having a constant speed control to an optional value, by detecting the counter electromotive force of the DC motor and then forming a negative feedback control loop.
CONSTITUTION: A control is secured for the resistance side of the 3rd resistance R3 by the serial connection between the fixed resistance r3' and the variable resistance r3". During this control, the parallel connection of the fixed resistances r2' and r2" is secured for the 2nd resistance R2 of other resistance side to obtain R2. Then based on the loop oscillation method, a control is given to variable resistance r3' to obtain R3/R2≈Ra/R1. After this control, the r2" is made disconnective to secure R2=r2' to complete the control. Here R1 is the 1st resistance and Ra is the armature resistance respectively. In this control system, whether the counter electromotive voltage control system has the loop oscillation or not is checked by giving an observation of the waveform by an oscilloscope to either one of the emitter (a) point of the transistors 3 and 4, the output terminal (b) point of the operational amplifier 2, the reverse-phase input terminal (c) point of the amplifier 2 and the positive-phase input terminal (d) point of amplifier 2.
