Abstract

1307643 Automatic control of current LICENTIA PATENT VERWALTUNGS GmbH 20 May 1970 [24 May 1969] 24326/70 Heading G3R [Also in Division H2] The field winding 1b of a separately excited D. C. motor is supplied by a control circuit whose input is derived from armature current pick-up 9, so that the field and armature currents rise together to give a series type characteristic in a non-field weakening range. The output of the motor is determined by the setting of generator 7, and the regulator 4, which receives an input from both 7 and pick-up 9, governs the timing of pulses from pulse generator 8 and hence the output of converter 2 to the armature 1a. The field winding 1b is similarly supplied via regulator 11, pulse generator 13 and converter 3, the control input of regulator 11 being derived from field-current pick-up 12 and armature current pick-up 9 via amplifier 6 and field weakening circuit 14, 15, 10. The transistor 10 is biased fully "ON" defining the non-field weakening range unless the control at the output of regulator 4 exceeds an amount, adjustable by means of resistor 16, which when amplified at 5 is passed to the base of transistor 10 decreasing its conductance and thus introducing progressive field weakening whose degree may be adjusted by varying resistors 14, 15. Preferably converter 2 is fully conducting before field weakening commences so that higher settings of generator 7 serve only to control the field weakening. Figs. 2-4 (not shown) show respectively the characteristics of regulator 4, amplifier 5, and the desired field current as a function of the output of regulator 4.
