  • DC motor having a braking circuit
    Patent number: 6876163
    Abstract: A circuit for controlling a motor's operation is disclosed. The circuit includes a relay and a motor braking circuit portion. The relay selectively interconnects a voltage source with one of a braking terminal and a motor terminal. The motor braking circuit portion has a motor brake switch connected on a first switch side to the motor terminal and a second switch side to the electrical ground. The brake switch is activated to brake the motor when the relay interconnects the voltage source with the braking terminal.
    Type: Grant

  • Constant spacing document feeder
    Patent number: 4318540
    Abstract: A constant spacing document feeder employs a motor control circuit which drives a feed wheel at an average speed which is dependent upon the length of a document.Since the spacing between successive documents is a function of the length of each following document, by varying the speed of the feed wheel in accordance with the length of each document, the spacing between each document can be maintained substantially constant.
