Title: Control circuits for the stepless adjustment of the speed of direct current motors
IPC: H02P7/29
Filed: 1972-02-02
Abstract: 1371854 Automatic speed control ROBERT BOSCH GmbH 2 Feb 1972 [3 Feb 1971] 4792/72 Heading G3R [Also in Division H2] A control circuit for the stepless adjustment of the speed of a D.C. motor 11 comprises main and control transitors 13, 18 inter-connected by a resistor 19 whose positive feedback, coupled with the charge and discharge of a capacitor 17, causes the transistors 13, 18 to switch on and off at a frequency which is a function of the capacity of capacitor 17 and the inductance of a choke 12, members 12, 17 serving to smooth the voltage applied to the motor 11 and so reduce its running noise. If the motor 11 is of the series field type, its field winding may constitute the choke 12. The mark-space ratio of the switching of transistor 13 is determined by the setting of a potentiometer 21 and the load of the motor, variation of the potentiometer setting providing the stepless speed adjustment. A typical cycling operation of the transistors 13, 18 is described, switch over being very fast to ensure a small power loss. The power loss in the transistor 13 may be further reduced by inserting between the emitter of the transistor 18 and the terminal 26 a diode, Fig. 2 (not shown) or two series-connected diodes or an equivalent stabilizing diode, the two diode embodiment corresponding to the use of a Darlington circuit in place of the transistor 13. A resistor is connected between the supply lead 24 and the emitter of transistor 18 to make the diode(s) conductive. The control circuit may be used in a fan drive for a motor vehicle, in which case the potentiometer 21 may be replaced by a controllable amplifier so that the motor speed may be a function of the internal temperature of the vehicle. The control circuit may also be used for the drive of a windscreen wiper.
