Abstract

709,768. Automatic speed control. SCHLOEMANN AKT.-GES. Feb. 11, 1952 [Feb. 13, 1951], No. 3545/52. Drawings to Specification. Class 38(4) In a speed control system for a motor having its armature energized through grid controlled rectifiers in accordance with the difference between an electrical quantity proportional to the speed and a. reference quantity, the error voltage is also used to control a relay operating a reversible servo-regulator in the field circuit.
