Abstract: 1,244,004. Control of D.C. motors. J. I. BROOME, B. H. ENGMAN, S. N. J. LINNMAN, and P. E. C. UDDEN. 1 Nov., 1968 [3 Nov., 1967], No. 51979/68. Heading H2J. [Also in Division G3] In a system for controlling the speed of a D.C. motor M the motor is energized by a switching semi-conductor T1 and a capacitor C is connected in a circuit in parallel with the motor, a speed responsive voltage being derived as the rate of change of the voltage across motor M during the off period of T1 and compared with a reference voltage indicative of the desired speed to control the on/off ratio of the semiconductor. In Fig. 5 motor M is supplied by a controlled rectifier T1 and a second S.C.R., T2 is used to switch off the first. T2 remains in its non-conducting condition for a fixed time determined by the charging of a timing capacitor C5. When T2 fires T1 is deprived of voltage and ceases to conduct The capacitor C is then effectively in series with the motor and the voltage at point A rises as capacitor C discharges through the motor, the rate of discharge being proportional to the speed at which motor M is turning. The voltage at point A is differentiated by capacitor C1 and the voltage across resistor R1 is therefore porportional to motor speed. A capacitor C2 is charged from R1 through a diode D1 and discharged through D2 when T1 is conducting. The irregular nature of the voltage across capacitor C2 is counteracted by a circuit R3, R4, C3 so that the voltage at B is a substantially steady voltage proportional to the actual speed of motor M. This voltage is compared with a reference voltage across a potentiometer P1. The difference, representing speed error, is detected by a transistor Tr3 and applied to the base of transistor Tr4 to control the rate of charging of a timing capacitor C4 which determines the off period of T1. When C4 is sufficiently charged D3 breaks down to trigger T1 to its conducting condition whereupon T2 is switched off and the cycle repeats. In a modified arrangement (Fig. 2, not shown) the controlled rectifiers T1, T2 may be replaced by a transistor.
