Abstract

426,304. Control of D.C. motors. SCHLOEMANN AKT.-GES., 13, Steinstrasse, Diisseldorf, Germany. Aug. 28, 1934, No. 24790. Convention date, Aug. 28, 1933. [Class 38 (iii)] [See also Group VIII] A motor control system for rhythmically varying the speed of a motor comprises a cam 7 which periodically short-circuits an adjustable portion of a resistance 5 connected in series with the field winding 4 of the motor. The same arrangement may be applied to a Ward- Leonard control system.
