Abstract

712,189. Automatic tension control. ENGLISH ELECTRIC CO., Ltd. Nov. 10, 1952 [Aug. 10, 1951], No. 18867/51. Class 38(4) Inertia compensation is provided in a constant current/tension control system for a D.C. coiler motor. The coiler motor 13 and a flywheel motor 18 are supplied through " measuring resistors " 14, 17 from bus bars 15 having a voltage varying substantially as the strip speed of the mill. The fields 13a, 18a are energized from an exciter 16 controlled by the difference betwen the I.R. drop across resistor 14 and the output of a reference generator 20 plus the I.R. drop across resistor 17. Under constant speed conditions the drop due to resistor 17 is negligible, but under varying speed, i.e. variable voltage applied to busbars 15, a variable drop is produced to oppose that in resistor 14 due to the inertia of motor 13. Specification 644,868 is referred to.
