Abstract

1,126,186. Automatic control of speed. MULLARD Ltd. May 6, 1966, No.20149/66. Heading G3R. [Also in Division H2] In a system wherein the speed of a series wound motor 2, 3 supplied from an A. C. source 4 is controlled by varying the firing angle of a thyratron or thyristor 1 in response to back e.m.f., the firing angle is further varied by a load current compensating circuit 9, 10, 11 to improve the speed/torque characteristic. Capacitor 7 and diode 8 are for phase control. Back e.m.f. is enhanced by the resistor 15 and diode 16 circuit as in Specification 1,126,185.
