Abstract: 1,141,197. Clutch control. BROOKHIRST IGRANIC Ltd. 14 Feb., 1967 [18 Feb., 1966], No. 7256/66. Heading F2L. An electromagnetic clutch control circuit, by which delay before the clutch coil current reaches maximum on energization and zero on de-energization is substantially reduced, comprises a four-arm bridge circuit having a terminal A connecting the coil C to the junction of first and second arms respectively connected to earth through a thyristor T and to an unsmoothed rectified A.C. negative or, as shown, positive line through a resistor R2, and a terminal B connecting the coil to the junction of third and fourth arms respectively connected to the positive, as shown, line through a resistor R3 and earth through a resistor R4 and a diode D2 in series; the resistances being such that when the thyristor is switched on by an input signal applied at I/P to its gate G current flows through R3, B, C, A, T, flux build-up being fast due to a low value of the resistor R3, and when the thyristor T is switched off, the input signal being removed, a reverse bias is applied to the coil through R2, A, C, B, R4 to rapidly reduce coil current. The reverse bias is insufficient to actuate the clutch due to small current through the resistor R2. A diode D1 in parallel with the resistor R2 conducts the transient current from the coil C after the thyristor is switched off, the current flowing in the loop C-D1-R3-C due to coil inductance. The diode D2 assists thyristor switch-off by preventing transient flow due to the coil from flowing in the loop C-A-T - D2-R4-B-C. Where negative supply is employed the polarities of the thyristor T and diodes Dl and D2 are reversed.
