  • Method for regulating the power supply to a direct-current motor and a device for the application of said method
    Patent number: 4468597
    Abstract: The power supply to an electric actuating motor is regulated by reducing the differences between current intensity or voltage and a reference value. Two transducers measure the current intensity and the voltage. A selection stage chooses the higher of the two values and a comparison stage delivers a difference signal with respect to the reference value established by a stage of the potentiometer type. A regulator produces an action which is compared within a comparator with a sawtooth signal emitted by an oscillator. Depending on the sign of the comparison, a control stage supplies the motor during a variable fraction of the period of the oscillations.
