Abstract
PURPOSE:To decrease the number of parts and to make a circuit suitable for integration by using a compensation-filter circuit realizing with a single amplifier a low- pass compensation characteristic, a high-pass secondary damping characteristic as well as an intermediate-pass gain set. CONSTITUTION:A compensation-filter circuit 9 is provided for giving an output signal of a speed detection circuit 3 to a motor driving circuit 6. Said circuit 9 is so formed that the resistance R1 is connected between the input points a and b, a capacitor C1 is connected between the point b and an output point c of the amplifier, and the resistance R2 is connected between the positive side input points d and b of the amplifier 10, also a capacitor C2 is connected between the input point d and the AC-type grounding spot, the resistance R3 and capacitor C3 are connected between the output point c and the negative side input point e, and the resistance R4 is connected between the input point e and the AC-type grounding point. Further, when the value of each capacitor is C1, C2, C3, the folding point angle frequency omegaH, omegaL, 1/(C1C2R1R2)<1/2>=omegaH, 1/C3(R3+R4)=omegaL, it is set to be omegaL< omegaH/2.
