Abstract

1529160 Automatic speed control NIPPON VICTOR KK 15 Aug 1977 [20 Aug 1976] 34205/77 Heading G3R In a speed-control system for a D.C. motor 10, the motor armature resistance Ro, feedback resistors R 1 , R 3 for differential operational amplifier 11 and amplifier input resistance R2 constitute a bridge circuit. This is fed at 17 with the result of a phase comparison between a reference signal and a signal generated by a tachometer 12 driven by the motor 10. The system compensates for the voltage drop across the motor armature resistance Ro, and regulates the speed of motor 10 which may drive magnetic tape in video recording- reproducing apparatus.
