Abstract

1,125,467. Automatic speed control. M. E. L. EQUIPMENT CO. Ltd. July 18, 1966 [Nov. 3, 19651, No. 46537/65. Heading G3R. The armature of a D. C. motor is supplied through an assembly of thyristors whose periods of conduction are determined by the magnitude of a speed-error signal derived from a comparator including a gain correction stage to compensate for non-linearity in the armature voltage-speed relationship. The reference voltage is derived from a potentiometer or transformer, and the signal representing speed from a motor-driven tachometer generator. The amplified error signal is applied to the base of transistor 11, the output from the gain correction stage being taken from the collector of the transistor. When Zener diode 16 is non- conductive, the gain of the circuit is fixed by resistors 12-14 and is of a high order. When the voltage across resistor 13 is sufficient to render the diode 16 conductive, resistors 15 replaces the resistor 13 to reduce the gain. The diode 16 is conductive over the linear portion of the armature voltage-speed characteristic.
