Abstract
1,168,041. Controlling clutches. SIEMENS A.G. 10 May, 1968 [10 May, 1967], No. 22428/68. Heading F2L. The energization of an electric slip clutch is controlled to maintain a desired output, speed. As shown, a diesel engine 1 drives a ship's propeller 2 through an electric slip clutch 4 and a gear 38. A machine telegraph 17 supplies a desired speed signal to a comparator 15 which receives a signal dependent on the actual output speed of the clutch from a tachometer 19. The signal from the comparator 15 is supplied to an amplifier 16 having a feedback 18, and the amplifier signal Md, which is a function of the difference between the actual and desired speeds, is fed to a multiplying device 34. Input and output signals supplied by tachometers 29, 19 are applied to a comparator 31 and the resulting signal is supplied to a function generator 32 which yields an output signal #(n1 - n2) the variation in which with variation in the input signal is approximately proportional to the reciprocal of the variation in the torque transmitted by the clutch with changes in the slip at constant excitation. The output signal f(n1 - n2) is applied to the multiplying device 34 which gives a signal U37 corresponding to the product of the signals Md and #(n1 - n2). The signal U37 is applied to a function generator 35 which produces a signal Ie* which is such that the magnetic flux produced in the clutch is proportional to the square root of the signal U37. Signal Ie* is fed to a comparator 22 which also receives a signal corresponding to the actual energizing current, and the difference between these signals is supplied to a variablegain amplifier 23 with a feedback path 24 and thence to a power amplifier 25 which supplies the energizing current to the clutch. A modified control for a slip clutch between an electric motor and a boiler feed pump has the function generator 32 supplying a signal f(n1 - n2) the variation in which with variation in input signal is approximately proportional to the variation in the torque transmitted by the clutch and is applied to a dividing device which also receives a desired output speed signal and passes the resultant signal to the function generator 35, the remainder of the circuitry being unaltered.
