Abstract
1526243 Automatic current control SIEMENS AG 2 Sept 1975 [26 Sept 1974] 36044/75 Heading G3R [Also in Division H2] A D.C. electric motor control circuit comprises a control amplifier RV driving a thyristor power amplifier TV which supplies current im to a motor M, a tachogenerator T driven by the motor, a coupling circuit linking the outputs of the tachogenerator and the control amplifier to produce an output voltage proportional to the current in the motor at any instant, and a comparator device for comparing the output voltage with two oppositely poled reference voltages to produce a resultant control setting voltage whenever a part of the output voltage exceeds either one of the reference voltages, the resultant control setting voltage acting on the control amplifier so that the current flowing in the motor does not exceed a value determined by the reference voltages. As shown, the output voltage is provided by an amplifier V and the comparator consists of two potentiometers P1 and P2, one or other of the diodes D1, D2 conducting when the corresponding reference voltage is exceeded.
