Abstract

641,778. Automatic control systems for electric motors. SEDGFIELD, H. B., DOWNES, F. A., and SPERRY GYROSCOPE CO., Ltd. Dec. 12, 1947, No. 29233/48. Divided out of 641,742. [Class 38 (iv)] [Also in Group XXXVII] The speed of a D.C. armature 10 is controlled by the centrifugal switch 16, 19 which is carried on the disc 26 mounted on the motor shaft and which short circuits the motor series field when the speed is below the datum value.
