Abstract
910,802. Control of D.C. motors. FAIRWEATHER, H. G. C. (Singer Manufacturing Co.). Oct. 13, 1960, No. 35058/60. Class 38 (3). [Also in Group XXXV] In a series commutator motor control circuit employing a junction transistor 13, excess voltage between the collector 15 and emitter 16 of the transistor is prevented by a resistor 17 connected across them and in series with the motor field 19 and its armature 18. The motor speed is determined by the voltage applied to the transistor base 14 from a potentiometer 11; the phasing of this voltage (which is half wave rectified at 24) is corrected by a capacitor 12 across a resistor 10. Voltage peaks due to sparking are limited by a resistor 26. The value of resistor 17 is such that the motor will not run when the transistor is cut off. A fusible, resistor 21 protects the motor circuit.
