Abstract: 883,385. Automatic control systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 9, 1958 [June 11, 1957], No. 18406/57. Class 38 (4). A system for controlling the brush position of an A.C. commutator motor 3 comprises a differential selsyn 7 having one winding supplied from a master selsyn 1 which rotates at a predetermined speed, and another winding supplied from a feedback selsyn 2 the rotation of which is proportional to the speed of the motor 3. The speed of a control motor 12 is a measure of a desired difference between the speeds of the machines 1 and 3. A differential gear DG has input spindles driven by the machines 7 and 12 respectively, and its output spindle is coupled to the brush-gear of the motor 3. Thus, the brush-position of the A.C. motor is modified to re-establish the required conditions if the speed of the motor deviates from its required value. As shown, the master selsyn is driven by the motor 11 of a Ward-Leonard set, and the generator 10 supplies the motor 12 through a resistor and a potentiometer 13 adjustment of which determines the desired difference in speeds between the master selsyn and the A.C. motor. In another arrangement the differential gear is replaced by a second differential selsyn which is connected between the machines 1 and 7 and has its rotor driven by the control motor. In this embodiment, the brush movement is controlled by the rotor of the first differential selsyn, Fig. 3 (not shown).
